Performance evaluation of leg and ear numbers in radio frequency identification systems (RFID) in sensitive livestock products in goat breeding / Avaliação de desempenho de números nas pernas e orelhas em sistemas de identificação por radiofrequência (RFID) em criação de caprinos

This study, evaluated the readability of electronic leg and ear tags in Saanen goats. Fifty-seven goats were identified with the electronic leg tags (ELT) and electronic ear tags (EET) from birth until the lactation period ends. Readability of ELT and EET was 96.30% and 90.55% respectively in static conditions at the end of 12 months. Foot and udder, with no infection rates for ELT and EET in calm and aggressive goats were 95.70% and 100%, respectively. No infection rates of foot and udder for ELT and EET in calm and aggressive goats were 95.70% and 100%, respectively. Tagging method and animal temperament was not statistically significant. As a result, low animal traceability with ear tags was determined by this study. Besides, it is suggested that smaller-sized tagging materials would be more accurate when the ankle was selected as a body area to place identification tags in goats. The resulting issue to be considered is that the leg tagging should not negatively affect the animal welfare and the foot and udder health. In the future, using a leg band in the identification of goats will become more widespread as it does not damage animals and has a high readability capacity.

Este estudo teve como objetivo avaliar a identificação eletrônica nos membros e orelhas de cabras da raça Saanen. Cinquenta e sete cabras foram identificadas eletronicamente nas pernas (ELT) e nas orelhas (EET) desde o nascimento até o término do período de lactação. A leitura de ELT e EET foi de 96,30% e 90,55%, respectivamente, em condições estáticas ao final de 12 meses. As taxas de infecção de pé e úbere, em cabras calmas e agressivas, foram de 95,70% e 100% para ELT e EET em animais sem infecção, respectivamente. Não foi encontrado efeito significativo do método de marcação e temperamento animal. Com o resultado, a baixa rastreabilidade dos animais com marcas de orelha foi determinada por este estudo. Além disso, sugere-se que materiais de etiquetagem de menor porte seriam mais precisos quando a região do metatarso do animal fosse selecionado como área corporal para a colocação de etiquetas de identificação em cabras. A questão resultante a ser considerada é que a marcação da perna não deve afetar negativamente o bem-estar animal e a saúde dos pés e do úbere. Futuramente, o uso de etiquetas na identificação de cabras será mais difundido, pois não agride os animais e tem alta capacidade de leitura.

Effect of GnRH administration on pregnancy-associated glycoproteins in dairy sheep with different reproductive status

Background: Measurement of pregnancy-associated glycoproteins (PAGs) by radioimmunoassay or enzyme-linked immunosorbent assay has been commonly used for early pregnancy diagnosis in ruminants. However, an accurately pregnancy detection depends on test antibody, breed and number of embryos. Only few studies have conducted to detect or predict animals at risk of late embrionic mortality (LEM) and to use hormonal interventions for embryo losses reducing, but this area is still open in sheep. The current study aimed to evaluate the effect of gonadotropin releasing hormone (GnRH) administration on Day 4 after artificial insemination on the pregnancy-associated glycoproteins in dairy sheep with different reproductive status in relation to pregnancy and late embrionic mortality detection. Materials, Methods & Results: Sixty-five East Friesian sheep were divided in 2 groups - I (Control group, n = 35) and II (GnRH group, n = 30) and sublected to estrus synchronization and artificial insemination (AI). Group I was not treated and Group II received 50 µg GnRH on Day 4 after AI. PAGs in blood serum were measured by Alertys Ruminant Pregnancy test on Days 4, 12, 20, 25 and 35 after AI and ultrasound pregnancy test was conducted on Days 20, 25, 35 and 60. Reproductive status (non-pregnant, pregnant and animals with LEM) was determined by ultrasound and the results between different groups were compared. The PAGs mean values according to reproductive status and Day after AI were analysed. Accuracy, sensitivity and specificity of the PAGs test for pregnancy diagnosis on Day 35 were calculated. On Day 20 after AI the pregnat sheep (83.3%) in group I tended to be higher than those (77.1%) in group II with decrease of 25.7% and 20% for the same groups on Day 25. On day 25 LEM was recorded in 33.3% and 24% in group I and II, respectively. The ultrasound exams on Day 60 confirmed the results from Day 25 after AI. A total value of non-pegnant, pregnant animals and LEM was 20%, 56.9% and 28.8%, respectively. The mean values of PAGs in animals with the same reproductive status in group I and II no differed statistically between Days 4 and 35 after AI. On Day 25 the PAGs values in LEM groups (0.126 ± 0.072 and 0.179 ± 0.029) were higher than those (0.062 ± 0.038 and 0.083 ± 0.023) in the non-pregnant groups, but no significan difference was deternined. On Day 35 after AI the mean values of PAGs (0.414 ± 0.125 and 0.421 ± 0.121) for the pregnant groups were significantly (P < 0.05) higher than those (0.078 ± 0.053 and 0.093 ± 0.034) for the non-pregnant groups. The values of PAGs in LEM groups on Day 25 (0.099 ± 0.062 and 0.113 ± 0.058) were decreased and close to the mean values in non-pregnant sheep. A significant effect of the day after AI on the PAGs values was evidenced in pregnant animals only (control r = 0.97 and GnRH r = 0.98; P < 0.05). The PAGs started to rise rapidly between Days 25 and 35 after AI. On Day 35 the accuracy (98%), the sensitivity (97.3%) and the specificity (100%) of the PAG test for pregnancy diagnosis were similar to the values (100%) for ultrasound method. Discussion: The gonadotropin treatment on Day 4 after AI tended to improve the reproductive performance in the sheep, but no significant effect of GnRH on the PAGs values in the animals with different reproductive status was found. The PAGs profiles in non-pregnant and LEM sheep were close and distinguishing between non-pregnant and LEM ewes on Day 35 was impossible. The PAGs values in pregnant sheep showed significantly (P < 0.05) increase between Days 25 and 35 after AI with higher mean values in pregnant than non-pregnant groups on Day 35 (P < 0.05). Alertys Ruminant Pregnancy test was a reliable for pregnancy detection in sheep on Day 35 after artificial insemination.

Gastrointestinal parasites in bullfrogs (Lithobates catesbeianus) in aquaculture production units in the Mexican central highlands / Parasitos gastrointestinais em rãs-touro (Lithobates catesbeianus) em unidades de produção aquícola do planalto central do México

Abstract In Mexico, intensive production of bullfrogs is one of the most important aquaculture activities, due to growing demand for their meat. Frogs can be hosts for several parasites that negatively affect their development and health. The objective of this study was to identify the presence of intestinal parasites in bullfrogs in aquaculture production units. Eighteen bullfrogs aquaculture production units were selected, and 20 animals (n=360) from each farm. Fecal samples were obtained by mucosal scraping and processed using the concentration method. The overall prevalence of intestinal parasites was 70.5%, and all farms had frogs infected by some species of parasite. Two species of parasites were identified: Eimeria sp. and Strongyloides sp. Significant differences were found regarding parasite prevalence between males and females (73.8% vs 58.8%) and regarding tibia length (5.5 vs 6.1 cm) and weight (168 vs 187 g) between parasitized and non-parasitized frogs. In conclusion, the present study showed a high prevalence of intestinal parasites, and morphometric alterations (weight, snout-cloaca length, radio-ulna length, tibia length and distance between parotid glands) were identified in the parasitized animals. These results provided useful information that will enable establishment of adequate control measures to help minimize the adverse effects of these parasites.

Resumo No México, a produção intensiva de rãs-touro é uma das atividades mais relevantes da aquicultura devido à sua crescente demanda. As rãs podem ser hospedeiras de vários parasitos que afetam negativamente seu desenvolvimento e sua saúde animal. O objetivo deste trabalho é identificar a presença de parasitas gastrointestinais (IPs) em rãs de boi em unidades de produção aquícola. Foram selecionadas 18 unidades de produção aquícola de rãs-touro, e de cada unidade 20 animais (n=360). Amostras fecais foram obtidas por raspagem de mucosas e processadas pelo método de concentração. A prevalência geral de IPs foi de 70,5%, todas as fazendas foram infectadas com algum parasita. Duas espécies de parasitas Eimeria sp. e Strongyloides sp. foram identificadas; encontrando-se diferenças significativas na prevalência entre machos e fêmeas (73,8% vs 58,8%), comprimento da tíbia (5,5 vs 6,1 cm) e peso (168 vs 187 g) entre rãs parasitadas e não parasitadas. Em conclusão, o presente estudo mostrou uma alta prevalência e alterações morfométricas (peso, comprimento do ronco-cloaca, comprimento do rádio-ulna, comprimento da tíbia e distância entre as glândulas parótidas) todas identificadas nos animais parasitados. Esses resultados mostram informações relevantes que permitirão o estabelecimento de medidas de controle adequadas para ajudar a minimizar os efeitos adversos desses parasitas.

Determination of water content in grains with microwave oven / Determinação do teor de água em grãos com forno micro-ondas

The determination of water content is essential for the maintenance of grain quality, and an evaluation of alternative methods for quantification allows to increase the efficiency of the process and bring benefits to the productive sector. The study aimed to analyze the efficiency of using microwave ovens to determine the water content in grains. The studywas carried out in a completely randomized design in a 5x6 factorial scheme, with fivespecies (peanut, sunflower, corn, soybean and wheat) and six microwave drying periods (0.5, 1, 1.5, 2, 2.5, and 3 min), with four replications. Data were subjected to descriptive analysis to characterize the samples, and regression analysis to analyze differences between methods as a function of drying time. The determination of water content in peanut, sunflower,corn,soybean and wheat grains in microwave is technically feasible, showing correlation with the determination in an oven by the standard method. The drying time in the microwave influences the water removal capacity of the grains. For peanut, sunflower,corn,soybean and wheat grains, the microwave drying time of 3 min showed greater similarity with the determination by the standard method.(AU)

A determinação do conteúdo de água é fundamental para manutenção da qualidade de grãos, sendo que a avaliação de métodos alternativos para quantificação permite elevar a eficiência do processo e ocasionar benefícios ao setor produtivo. O estudo teve como objetivo analisar a eficiência da utilização de forno micro-ondas para determinação do teor de água em grãos. O estudo foi conduzido em delineamento inteiramente casualizado em esquema fatorial 5x6, sendo cincoespécies (amendoim, girassol, milho, soja e trigo) e seis períodos de secagem em micro-ondas (0,5; 1; 1,5; 2; 2,5 e 3 min), com quatro repetições. Osdados foram submetidos a análise descritiva para caracterização das amostras, e análise de regressão para análise das diferenças entre métodos em função do tempo de secagem. A determinação do teor de água em grãos de amendoim, girassol,milho,soja e trigo em micro-ondas é tecnicamente viável, apresentando correlação com a determinação em estufa pelo método padrão. O tempo de secagem no micro-ondas influencia na capacidade de remoção de água dos grãos. Para os grãos de amendoim, girassol,milho,soja e trigo, o tempo de secagem por micro-ondas de 3 min apresentou maior similaridade com a determinaçãopelo método padrão.(AU)

RESUMO: Este estudo teve como objetivo avaliar a identificação eletrônica nos membros e orelhas de cabras da raça Saanen. Cinquenta e sete cabras foram identificadas eletronicamente nas pernas (ELT) e nas orelhas (EET) desde o nascimento até o término do período de lactação. A leitura de ELT e EET foi de 96,30% e 90,55%, respectivamente, em condições estáticas ao final de 12 meses. As taxas de infecção de pé e úbere, em cabras calmas e agressivas, foram de 95,70% e 100% para ELT e EET em animais sem infecção, respectivamente. Não foi encontrado efeito significativo do método de marcação e temperamento animal. Com o resultado, a baixa rastreabilidade dos animais com marcas de orelha foi determinada por este estudo. Além disso, sugere-se que materiais de etiquetagem de menor porte seriam mais precisos quando a região do metatarso do animal fosse selecionado como área corporal para a colocação de etiquetas de identificação em cabras. A questão resultante a ser considerada é que a marcação da perna não deve afetar negativamente o bem-estar animal e a saúde dos pés e do úbere. Futuramente, o uso de etiquetas na identificação de cabras será mais difundido, pois não agride os animais e tem alta capacidade de leitura.

Carpal valgus angle deviation in Thoroughbred foals corrected using single transphyseal screw implant / Correção de desvio angular valgo do carpo em potros Puro-sangue com implante de parafuso transfiseal único

The objective of this study was to demonstrate the effectiveness of the single transphyseal screw technique in foals diagnosed with carpal valgus deviation. This study included 22 thoroughbred animals of both sexes, with a mean age of 30 days. All animals had a carpal valgus deviation >5° with irregular development of the distal epiphysis of the radius. All animals were surgically treated to correct the carpal valgus deviation by creating a bridge using a single transphyseal screw. Surgical intervention was performed for 40 limbs, comprising 19 right and 21 left thoracic limbs. This corresponded to four animals with carpal valgus deviation >5° in only one of the limbs and 18 with the deviation in both limbs. It was observed that 38/40 treated limbs (95%) achieved normal angulation according to the literature, i.e., angulation between 0° and 5°. No statistical differences were observed between the affected limbs. The single transphyseal screw technique can be used for the correction of carpal valgus deviation in foals. It is indicated in animals with an average age of 30 days (20-55 days), as its main advantages are rapid application, simple execution, and limited trans- and post-surgical complications, making it an effective procedure in thoroughbred foals with carpal valgus angular deviation.

O objetivo do presente estudo foi demonstrar a viabilidade da aplicação da técnica de parafuso único transfiseal em potros, com diagnóstico de desvio valgo do carpo. Foram selecionados 22 animais, da raça PSI, com idade média de 30 dias, de ambos os sexos. Todos os animais apresentavam desvio valgo do carpo acima de cinco graus, com desenvolvimento irregular da epífise distal do rádio. Os animais foram submetidos à cirurgia corretiva para o desvio valgo do carpo por meio da realização de ponte com um único parafuso transfiseal. Foram submetidos à intervenção cirúrgica 40 membros, divididos entre membros torácicos direito e esquerdo 19 e 21, respectivamente, que corresponderam a quatro animais com desvio acima de 5 graus valgo do carpo em apenas um dos membros e 18 animais com o procedimento nos dois membros. Observou-se que 38 dos 40 membros tratados, ou seja, 95%, retornaram a uma angulação considerada normal, entre zero e cinco graus Dois animais apresentaram infecção do implante, de maneira que eles reduziram a angulação, porém não o suficiente para enquadrá-los na angulação normal estabelecida pela literatura. Não houve diferença estatística entre os membros acometidos. A técnica de aplicação do único parafuso transfiseal pode ser indicada para correção do desvio valgo do carpo em potros. Deve ser indicada em animais com idade média de 30 dias (20 a 55 dias de vida), por ter como principais vantagens aplicação rápida, execução simples e com limitadas intercorrências trans e pós-cirúrgicas.

Fraturas apendiculares em cães e gatos: métodos de tratamento e desfechos / Appendicular fractures in dogs and cats: treatment methods and outcome

O objetivo deste estudo retrospectivo foi identificar a ocorrência de fraturas apendiculares em cães e gatos, os métodos de tratamento e os resultados obtidos com os mesmos, no Hospital Veterinário (HV) da Universidade Regional do Noroeste do Estado do Rio Grande do Sul (Unijuí), no município de Ijuí - RS, no período de abril de 2013 a abril de 2022. De um total de 370 procedimentos cirúrgicos para tratamento de fraturas do esqueleto apendicular, 117 foram em fêmur (31,6%), 77 em tíbia e fíbula (20,8%), 62 em rádio e ulna (16,8%), 49 em úmero (13,2%), 45 em pelve (12,2%), 7 em metatarso e metacarpo (1,9%), 7 em tarso e carpo (1,9%), 4 em escápula (1,1%) e 2 em falanges (0,5%). O número de procedimentos foi superior ao número de animais, pois alguns apresentavam mais de uma fratura em diferentes ossos. Entre os 329 animais reportados neste estudo, concluiu-se que a principal causa de fraturas em cães e gatos foi atropelamento, sendo os filhotes os mais acometidos e as fraturas femorais as mais frequentes. Os fixadores esqueléticos externos destacaram-se como o método mais utilizado e o desfecho das osteossínteses foi satisfatório, sendo que a maior casuística correspondeu a fraturas cicatrizadas.

This retrospective study aimed to identify the occurrence of appendicular fractures in dogs and cats, treatment methods, and results obtained with them, at the Veterinary Hospital (VH) of the Regional University of the Northwest of the State of Rio Grande do Sul (Unijuí), in the city of Ijuí/RS, from April 2013 to April 2022. A total of 370 surgical procedures for the treatment of fractures of the appendicular skeleton was performed: 117 were in the fêmur (31,6%), 77 in the tíbia and fíbula (20,8%), 62 in the radius and ulna (16,8%), 49 in the humerus (13,2%), 45 in pélvis (12,2%), 7 in metatarsus and metacarpus (1,9%), 7 in tarsus and carpus (1,9%), 4 in the scapula (1,1%), and 2 in phalanges (0,5%). The number of procedures was higher than the number of animals, as some had more than one fracture in different bones. Among the 329 animals reported in this study, it was concluded that the main cause of fractures in dogs and cats was being run over, puppies were the most affected, and femoral fractures were the most frequent. External skeletal fixators stood out as the most used method and the outcome of osteosynthesis was satisfactory, with the largest number of cases corresponding to healed fractures.

Anatomy and surgical approach to the humerus, radius and ulna of common sloth (Bradypus variegatus) / Anatomia e acesso cirúrgico ao úmero, rádio e ulna de preguiça-comum (Bradypus variegatus)

The surgical clinic of wild animals has increased in routine veterinary, where fractures by traumas are of frequent occurrence. This study determined the surgical accesses for osteosynthesis of the diaphyses of the humerus, radius and ulna of common sloth (Bradypus variegatus). Seven cadavers of B. variegatus were used for determination of the muscles of the thoracic limb, as well as the most important vessels and nerves, and better bone area for fixation of internal implants. The structural conformation of the radius and ulna in Bradypus variegatus were like those described in the literature for domestic animals but the humerus presented differences in the distal extremity because it was flattened. The musculature of Bradypus variegatus showed similarities with domestic animals. Due the different conformation of the humerus the surgical access to this bone can be performed by lateral approach, from the incision of M. triceps brachii lateral head, for fixation of the implant on the lateral side of the bone. Surgical access to the radius shaft can be performed by craniolateral approach, by incising the muscular fascia and separation of the cranially M. common digital extensor, and lateral digital extensor caudally. In ulna, a caudal access to the bone can be performed followed by release of the insertion m. flexor carpoulnar for placement of the internal implant on the lateral bone face.

A clínica cirúrgica de animais silvestres tem se intensificado na rotina veterinária, onde fraturas por traumas são frequentes. O objetivo deste estudo foi a determinação de acessos cirúrgicos para osteossíntese das diáfises do úmero, rádio e ulna de preguiça-comum (Bradypus variegatus). Sete cadáveres de B. variegatus foram utilizados para determinação dos músculos do membro torácico, bem como dos vasos e nervos mais importantes, e melhor área óssea para fixação de implantes internos. A conformação estrutural do rádio e da ulna em B. variegatus eram similares às descritas na literatura para animais domésticos, o úmero apresentou diferenças na extremidade distal pois apresentou-se achatado. A musculatura de B. variegatus mostrou semelhanças com os animais domésticos. Devido à diferente conformação do úmero o acesso cirúrgico a este osso pode ser realizado por abordagem lateral, a partir da incisão do M. tríceps braquial cabeça lateral, para fixação do implante na face lateral do osso. O acesso cirúrgico à diáfise do rádio pode ser realizado por abordagem craniolateral, por incisão da fáscia muscular e separação cranialmente do M. extensor digital comum e extensor digital lateral caudalmente. Na ulna, pode-se realizar um acesso caudal ao osso seguido de liberação da inserção do M. flexor carpoulnar para colocação do implante interno na face lateral do osso.

Does financial literacy inevitably lead to access to finance services? Evidence from rural Ghana / A educação financeira leva inevitavelmente ao acesso a serviços financeiros? Provas da zona rural de Gana

This study examined the determinants of financial literacy (FL) and its impact on access to financial services (AFS), using data collected from rural Ghana. A two-stage residual inclusion model is utilized to address the selection bias issue. The results showed that FL is affected by household heads' age, gender, education, asset ownership, homeownership, and economics education. The results revealed that FL is significant and positively related to AFS, but its square shows an inverse relation with saving mobilization. This indicated a non-linear relationship between FL and AFS. Moreover, we find that FL has a larger AFS impact for households with high-income and male household heads relative to their counterparts. The study recommended that the government can initiate the creation of a rural committee to educate rural residents on financial issues through radio broadcasting and meetings. Our findings highlighted the importance of FL on AFS in enhancing the welfare of rural households.

Este estudo examina os determinantes da educação financeira (FL) e seu impacto no acesso a serviços financeiros (AFS), usando dados coletados na zona rural de Gana. Um modelo de inclusão residual de dois estágios é utilizado para abordar a questão do viés de seleção. Os resultados mostram que a FL é afetada pela idade, sexo, educação, propriedade de ativos, propriedade e educação econômica dos chefes de família. Os resultados revelam que FL é significativo e positivamente relacionado ao AFS, mas seu quadrado mostra uma relação inversa com a mobilização de poupança. Isso indica uma relação não linear entre FL e AFS. Além disso, notou-se que o FL tem um impacto maior de AFS para famílias com alta renda e chefes de família do sexo masculino em relação às suas contrapartes. O estudo recomendou que o governo pode iniciar a criação de um comitê rural para educar os residentes rurais sobre questões financeiras por meio de radiodifusão e reuniões. Nossos resultados destacam a importância do FL no AFS para melhorar o bem-estar das famílias rurais.

Fratura exposta do fêmur em preguiça-real (Choloepus didactylus) - tratamento e reabilitação / Open fracture of the femur in a two-toed sloth (Choloepus didactylus) - treatment and rehabilitation

Background: The Choloepus didactylus is characterized by having 2 fingers on the forelimbs and 3 on the hind limbs, being found more frequently in northern South America, in countries such as Venezuela, Guyana, Ecuador, Peru, and Brazil. In Brazil, deforestation of the Amazon rainforest has threatened the survival of C. didactylus. In addition, these animals can be affected by several diseases, being those of the musculoskeletal system with limited reports. Thus, the present report aimed to describe the treatment and evolution of an open fracture of the femur in a free-living Choloepus didactylus, which after rehabilitation was released back to the wild. Case: A free-living female two-toed sloth (Choloepus didactylus), weighing 7.0 kg, was found in Manaus city and referred to the Wild Animal Treatment Center (CETAS - IBAMA-AM) located in Amazonas, Brazil, after initial treatment and osteosynthesis in a private clinic (CVMinasPet). According to history, the animal had suffered electrocution 30 days ago and, as a result, had an extensive wound that resulted in the exposure of the knee joint, distal fracture of the femur, and areas of necrosis in the right pelvic limb. After cleansing of the area and removal of necrotic tissues, the fracture was stabilized with the cross-pinning technique (2 Steinmann pins). Then, the stifle joint was stabilized with external skeletal fixation (Type 1b, unilateral biplanar). The external fixator and cross-pins were removed 2 months after the surgical procedure, being observed bone healing. Next, the animal underwent physical rehabilitation for 30 days. After the rehabilitation period, a microchip and a radio collar were applied, and the sloth was released back to the wild. Discussion: Electrocution has been one of the causes of wildlife rescue, with consequences varying depending on the degree of the burn. Generally, the burn is most severe at the entry and exit sites. Since suspensory quadrupedal locomotion requires that sloths have specialized hands and feet to connect with the supports, probably the animal of the current report touched the right pelvic limb on a high-tension pole. The cross-pinning technique combined with the external fixator was used because the animal had an exposed Salter-Harris type I fracture with soft tissue loss. The younger the animal presents physeal fractures, the greater is the chance of developing growth abnormalities due to growth plate closure caused by fracture type or immobilization method. Since the sloth was a free-living animal, the age was unknown. However, pelvic limb length discrepancy was not observed after removing the implants. Culture and antimicrobial susceptibility test were not done and may be considered a limitation of this report. However, the application of ceftriaxone was adequate to control the infection, since the animal did not show signs of infection or draining sinus tracts. Ceftriaxone is a third-generation antibiotic that can be used in chronic osteomyelitis. In addition, the animal in the present report showed good adaptation to captive conditions that contributed to the clinical management. The longevity of the sloth in captivity can reach more than 30 years, but the goal is always to return the animal to nature after the treatment. Surgical treatment of the fracture and physical therapy after implant removal allowed this action in the current report, confirmed by monitoring with the radio collar.

Equine podotrochlear apparatus - histologic characterization

Background: The navicular syndrome may be associated with alterations in other podotrochlear apparatus components,such as the deep digital flexor tendon, collareral sesamoid and distal sesamoid ligaments, podotrochlear bursa and distalsesamoid bone. However, the clinical significance and nature of these changes are not well understood, many of descriptive reports about distal sesamoid bone lesions are rarely accompanied by a complete and comprehensive comparisonwith animals of the control group. The aim of this study was to described histologically findings of the podrotrochlearapparatus components, allowing the understanding of the inserts and their microscopic appearance, thus providing thefuture recognize of their alterations.Materials, Methods & Results: Fourteen samples of the podotrochlear apparatus were taken out of 44 equine thoracic limbsspecimens, separated at the radiocarpal joint of Crioulo and Thoroughbred horses, with an average age of 6.0-year-old,coming from a private clinic in southern Brazil.

Equine podotrochlear apparatus - histologic characterization

Background: The navicular syndrome may be associated with alterations in other podotrochlear apparatus components,such as the deep digital flexor tendon, collareral sesamoid and distal sesamoid ligaments, podotrochlear bursa and distalsesamoid bone. However, the clinical significance and nature of these changes are not well understood, many of descriptive reports about distal sesamoid bone lesions are rarely accompanied by a complete and comprehensive comparisonwith animals of the control group. The aim of this study was to described histologically findings of the podrotrochlearapparatus components, allowing the understanding of the inserts and their microscopic appearance, thus providing thefuture recognize of their alterations.Materials, Methods & Results: Fourteen samples of the podotrochlear apparatus were taken out of 44 equine thoracic limbsspecimens, separated at the radiocarpal joint of Crioulo and Thoroughbred horses, with an average age of 6.0-year-old,coming from a private clinic in southern Brazil. The thoracic limbs specimens were refrigerated at 4ºC at the clinic and thenthey were sent to the University Federal of Santa Maria (UFSM). Once at the University laboratory, the specimens weredissected to isolate the podotrochlear apparatus from each one. Subsequently, transversal and longitudinal samples fromthe distal sesamoid bone, deep digital flexor tendo, distal sesamoid ligament, colateral sesamoid ligament, were collectedand podotrochlear bursa which were processed at the Veterinary Pathology Laboratory of the UFSM and University Federalof Santa Catarina (UFSC). The tissues samples were fixed in a 10% formaldehyde solution for 14 days and routinely processed for histology. The samples were sectioned at 3 µm and stained using the hematoxylin-eosin (H-E) routine method.The bone samples, after fixation, underwent a decalcified process in a formic acid-sodium citrate aqueous...(AU)

Métodos ultrassonográficos na avaliação das afecções prostáticas em cães ­ revisão de literatura / Ultrasonographic methods in the evaluation of prostatic disorders in dogs ­ paper review

O objetivo desta revisão foi descrever as principais técnicas de avaliação e achados ultrassonográficos da próstata canina. A ultrassonografia é o método de escolha para avaliação da glândula prostática, sendo imprescindível como auxílio no diagnóstico na detecção de anormalidades, principalmente quando há suspeita da presença de tumores. Com inovação dos equipamentos, surgiram técnicas complementares à ultrassonografia modo Bidimensional (B), tais como Doppler, ultrassonografia contrastada e elastografia, que aumentam a acurácia diagnóstica. O Doppler fornece informações sobre arquitetura vascular e aspectos hemodinâmicos dos vasos sanguíneos. A ultrassonografia contrastada permite determinar parâmetros relacionados à perfusão sanguínea das estruturas pelos agentes de contraste (ex.: microbolhas), definindo, portanto, padrões de alta e baixa intensidade da arquitetura vascular. A elastografia proporciona a avaliação da rigidez tecidual tanto de forma qualitativa, por meio de elastogramas, quanto quantitativa, por meio das velocidades de cisalhamento. Espera-se que esta revisão possa contribuir com informações relevantes aos leitores e veterinários da área de ultrassonografia e reprodução animal.(AU)

The purpose of this review was to describe the main assessment techniques and ultrasound findings of the canine prostate. Ultrasonography is the method of choice for assessing the prostate gland, being essential as an aid in the diagnosis in the detection of abnormalities, especially when the presence of tumors is suspected. With the innovation of the equipment, complementary techniques to B-mode ultrasonography have emerged, such as Doppler, contrasted ultrasound and elastography, which increase the diagnostic accuracy. Doppler provides information on vascular architecture and hemodynamic aspects of blood vessels. Contrast ultrasonography allows to determine parameters related to the blood perfusion of structures by contrast agents (eg, microbubbles), thus defining high and low intensity patterns of vascular architecture. ARFI elastography provides assessment of tissue stiffness both qualitatively, using elastograms, and quantitative, using shear speeds. It is hoped that this review can contribute with relevant information to readers and veterinarians in the area of asound and animal reproduction.(AU)

Osteoma in Agapornis roseicollis / Osteoma em Agapornis roseicollis

Neoplasias are important causes of illness and death in domestic animals. However, in birds, they are less frequent compared with other species such as dogs and cats. Moreover, benign tumors of bone are even less frequent in captive birds being considered sporadic, which make it a poorly understood entity due to the lack of clinical and histopathological data. Thus, we present a case of an osteoma in a Peach-faced lovebird (Agapornis roseicollis) approaching clinical and morphological aspects. A two-years-old lovebird was referred to the veterinary hospital with a 4-month evolution round to oval tumoral mass on the wing. The nodule was firm, painful when manipulated. Radiographic examination revealed a radiopaque mass in the radius and ulna bones. The animal has died during the surgical procedures. The affected wing was submitted to pathology service and histopathology revealed an osteoma.

As neoplasias são importantes causas de doença e morte em animais domésticos. No entanto, em aves, são menos frequentes em comparação com outras espécies, como cães e gatos. Além disso, tumores ósseos benignos são ainda menos frequentes em aves de cativeiro sendo considerados esporádicos, o que o torna uma entidade pouco compreendida devido à falta de dados clínicos e histopatológicos. Assim, apresentamos um caso de osteoma em Periquito cara-de-pêssego (Agapornis roseicollis) abordando aspectos clínicos e morfológicos. Um periquito de dois anos foi encaminhado ao hospital veterinário com uma massa tumoral ovalada na asa com evolução de 4 meses. O nódulo era firme, doloroso quando manipulado. O exame radiográfico revelou uma massa radiopaca nos ossos rádio e ulna. O animal morreu durante os procedimentos cirúrgicos. A asa afetada foi submetida ao serviço de patologia e a histopatologia revelou um osteoma.

Cytotoxicity of iodine-131 radiopharmaceutical in tumor and non-tumor human cells and radioprotection by integral juices of Vitis labrusca L / Citotoxicidade do radiofarmacêutico iodo-131 em células humanas tumorais e não tumorais e radioprotecção por sucos integrais de Vitis labrusca L

Iodine-131 (I-131) radioisotope it causes the formation of free radicals, which lead to the formation of cell lesions and the reduction of cell viability. Thus, the use of radioprotectors, especially those from natural sources, which reduce the effects of radiation to healthy tissues, while maintaining the sensitivity of tumor cells, stands out. The objective of the present study was to evaluate the cytoprotective/radioprotective effects of whole grape juices manufactured from the conventional or organic production systems, whether or not exposed to ultraviolet (UV-C) light irradiation. The results showed that I-131 presented a cytotoxic effect on human hepatocellular cells (HepG2/C3A) at concentrations above 1.85 MBq/mL, after 24 and 48 hours of treatment, though all concentrations (0.0037 to 7.40 MBq/mL) were cytotoxic to non-tumor human lung fibroblast (MCR-5) cells, after 48 hours. However, grape juices (10 and 20 µL/mL) did not interfere with the cytotoxic effect of the therapeutic dose of I-131 on tumor cells within 48 hours of treatment, while protecting the non-tumor cells, probably due to its high antioxidant activity. In accordance with their nutraceutical potential, antioxidant and radioprotective activity, these data stimulate in vivo studies on the use of natural products as radioprotectants, such as grape juice, in order to confirm the positive beneficial potential in living organisms.

O radioisótopo iodo-131 (I-131) causa a formação de radicais livres, que levam à formação de lesões celulares e redução da viabilidade celular. Assim, destaca-se a utilização de radioprotetores, principalmente de origem natural, que reduzem os efeitos da radiação nos tecidos saudáveis, mantendo a sensibilidade das células tumorais. O objetivo do presente estudo foi avaliar os efeitos citoprotetores/radioprotetores de sucos de uva integral fabricados em sistemas de produção convencional ou orgânico, expostos ou não à radiação ultravioleta (UV-C). Os resultados mostraram que o I-131 apresentou efeito citotóxico nas células hepatocelulares humanas (HepG2/C3A) em concentrações acima de 1,85 MBq/mL, após 24 e 48 horas de tratamento, embora todas as concentrações (0,0037 a 7,40 MBq/mL) fossem citotóxicas para células de fibroblasto de pulmão humano não tumoral (MCR-5), após 48 horas. No entanto, os sucos de uva (10 e 20 µL/mL) não interferiram no efeito citotóxico da dose terapêutica de I-131 nas células tumorais em 48 horas de tratamento, protegendo as células não tumorais, provavelmente devido ao seu alto poder antioxidante. atividade. De acordo com seu potencial nutracêutico, atividade antioxidante e radioprotetora, esses dados estimulam estudos in vivo sobre o uso de produtos naturais como radioprotetores, como o suco de uva, a fim de confirmar o potencial benéfico positivo em organismos vivos.

Malformações congênitas em ovinos - surto causado por Mimosa tenuiflora / Congenital malformationsin sheep - outbreak caused by Mimosa tenuiflora

Background: Congenital malformations are anomalies, structural or functional, that occur during the embryonic or fetal phase. There are several causes, one of which is the ingestion of toxic plants. Considering the importance of native toxic plants in the Central Backlands of Ceará state - Brazil, this paper reports cases of congenital malformations in sheep due to ingestion of Mimosa tenuiflora. Cases: Cases of abortion and malformations in sheep, were monitored in a rural property in the municipality of Piquet Carneiro with 20 ruminants (15 sheep and 5 cows) raised on a semi-intensive regime. The animals grazed during the day and were supplemented with corn, having unrestricted access to dam water. On its margins, there was a large amount of jurema preta (Mimosa tenuiflora), which the owner reported that the sheep consumed daily. The owner was unaware of the toxicity of M. tenuiflora but reported that cases of malformations had already occurred on his property some time ago. In an interval of approximately 12 days, 3 sheep miscarriage fetuses with multiple malformations. Malformed fetuses were referred for anatomopathological examination at the Animal Pathology Laboratory of the Veterinary Hospital of Federal University of Campina Grande (UFCG), Campus Patos, Paraíba, Brazil. The fetuses were necropsied and tissue samples of the nervous system and organs from the thoracic and abdominal cavities were collected, fixed in 10% neutral buffered formalin, routinely processed for histopathology, included in paraffin, cut into 3 µm sections and stained with hematoxylin and eosin (HE). At necropsies were observed permanent contracture of the thoracic limb joints (arthrogryposis), particularly at the radio-carpal joints; incomplete medial fusion of the palatal bone, with communication between the oral and nasal cavities (palatoschisis); hypoplasia of the mandibular bone (micrognathia); unilateral hypoplasia of the incisive bone with discontinuity of the upper lip (cheiloschisis); unilateral hypoplasia of the eyeball (microphthalmia); lateral curvature of the cervical spine (scoliosis); and chest deformity characterized by ventral protrusion of the sternum and ribs (Pectus carinatum). At the histopathological evaluation of the tissues, no alterations were observed. Discussion: The diagnosis was based on the epidemiological, clinical, and anatomopathological findings. The semi-intensive management system applied on the property predisposed the sheep to ingestion of M. tenuiflora, which grows abundantly on the property and throughout the Central Backlands of Ceará, Brazil, with a high rate of geographical coverage. Despite that, most rural producers, especially subsistence farmers, are unaware of the toxic and teratogenic properties of the plant. In the northeastern, where there are long periods of drought coupled with forage shortages, poisoning by M. tenuiflora is a common cause of malformation and mortality in lambs. Therefore, it is necessary to adopt preventive measures in herds, such as raising awareness among producers about the toxic potential of some native plants and the practice of producing and supplying silage to animals, so that native toxic plants are not the only food source during the scarcity period.

Consolidação de fraturas de tíbia em coelhos / Consolidation of tibia fractures in rabbits

Background: Disorders of the locomotor system are among the main treatments for this species, among the main causes are falls from a cage, arms or stairs and aggression by animals, such as dogs and cats. Biological osteosynthesis promotes early formation of secondary bone callus and allows a less accurate reconstruction of difficult interfragmentary apposition of 100% of the fragments. The objective of this work is to report the method of external immobilization with an aluminum channel aiming at the use of bone biology for the healing of unexposed tibial fractures in 3 rabbits (Oryctolagus cuniculus). Cases: Between 2020 and 2021, 3 cases of rabbits with unexposed tibial fractures were treated at the Veterinary Hospital. The 3 patients were diagnosed through physical examination and radiographic examination. All patients underwent anesthesia, underwent external immobilization with an aluminum channel, received analgesics and anti-inflammatory drugs, and recommended rest and care with the maintenance of external immobilization. Approximately at 30 days of rigid immobilization, all cases were evaluated by means of radiographic examination revealing the formation of bone callus at different post-immobilization times in the case 1 - 30 days, case 2 - 23 days and case 3 - 37 days. Discussion: Some surgical principles in rabbits must be followed, such as preserving vascularity if the open technique is decided, providing adequate diet, controlling edema, promoting analgesia and deciding on closed reduction if the fracture is recent and stable. The external coaptation method is a non-invasive method for the treatment of fractures and is also indicated with a high success rate for fractures of metacarpal, metatarsal and phalange bones in rabbits. The patient's age contributed to the early healing, which corroborates with case 1 (3-month-old), case 2 (6-month-old) and a little later the healing in case 3 (24-month-old), allowing unrestricted use of the member. It is worth reinforcing the point of view which defends that "biological osteosynthesis" promotes a favorable environment, especially in the preservation of the vascular supply of the periosteum when compared to traditional open surgical approaches. In this species, the surgical approach is a challenge due to the fact that the bones break or crack very easily, because the bones have a low density and higher mineral composition. Together, the skeleton represents 7% of the body weight, lower when compared to dogs and cats, which is 12%. In addition to these factors, rabbits are prone to secondary fractures, postoperative infections and rapid development of osteomyelitis, which significantly worsens the prognosis. The aluminum used in the manufacture of the aluminum channel has properties that offer resistance, lightness and radio transparency radiographic examination without removal of the channel, avoiding excessive micro-movement of the focus of the fracture due to lack of stabilization and possible refracture of the tibia. Rigid external immobilization with an aluminum channel was satisfactory in the 3 patients evaluated and preserved bone biology and anatomical axis. The treatment of choice was easy to apply, in addition to enabling better radiographic follow-up, promoting rapid bone healing for patients and early use of limbs without restrictions. However, for the effectiveness of the technique, the collaboration of tutors is essential.

Fraturas apendiculares em cães e gatos: casuística / Appendicular fractures in dogs and cats: casuistry

A ocorrência de fraturas é comum em cães e gatos, principalmente as ocasionadas por atropelamento. Diante disso, um estudo retrospectivo de cães e gatos atendidos entre abril de 2013 e abril de 2020 no Hospital Veterinário da Universidade Regional do Noroeste do Estado do Rio Grande do Sul foi realizado. O estudo teve como objetivo identificar a prevalência das fraturas apendiculares, a etiologia e o tratamento. De um total de 222 animais, 197 (88,7%) eram cães e 25 (11,3%) eram gatos, os quais apresentaram 254 fraturas apendiculares. Quanto às fraturas, os seguintes resultados foram observados: 86 fraturas de fêmur (33,9%), 58 fraturas de tíbia e fíbula (22,8%), 24 fraturas da pelve (9,4%), 39 fraturas do rádio e da ulna (15,4%), 40 fraturas do úmero (15,7%), 3 fraturas de escápula (1,2%), 3 fraturas de metatarso (1,2%) e 1 fratura de metacarpo (0,4%). Os animais mais afetados foram os cães: machos (n=100; 57,8%), com idade de até três anos (n=123; 62,4%), sem raça definida (n=95; 45%), de porte pequeno (n=123; 62,4%). Desta forma, conclui-se que o perfil de animais com fraturas apendiculares da Região Noroeste do Rio Grande do Sul é: cães machos, sem raça definida, jovens, de pequeno porte, sendo que o fêmur foi o osso mais acometido devido a acidentes automobilísticos.

The occurrence of fractures is common in dogs and cats, especially those caused by being run over. Therefore, a retrospective study of dogs and cats attended between April 2013 and April 2020 at the Veterinary Hospital of the Regional University of the Northwest of the State of Rio Grande do Sul was carried out. The study aimed to identify the prevalence of appendicular fractures, the etiology, and the treatment. Among 222 animals, 197 (88.7%) were dogs and 25 (11.3%) were cats, which presented 254 appendicular fractures. Regarding the fractures, the following results were observed: 86 fractures of femur (33.9%), 58 fractures of tibia and fibula (22.8%), 24 fractures of pelvis (9.4%), 39 fractures of radius and ulna (15.4%), 40 fractures of humerus (15.7%), 3 fractures of scapular (1.2%), 3 fractures of metatarsal (1.2%), and 1 fracture of metacarpal (0.4%). The most affected animals were dogs: male (n = 100; 57.8%), aged up to three years (n=123; 62.4%), mixed breed (n=95; 45%), small size (n=123; 62.4%). In conclusion, the animals profile with appendicular fractures of the Northwest Region of Rio Grande do Sul is: male dogs, mixed breed, young, small, and with femur as the most affected bone due to automobile accidents.

Correlation of serum acute-phase proteins with bone repair in rabbits (Oryctolagus cuniculus) submitted to partial radio ostectomy / Correlação do proteinograma sérico com a reparação óssea em coelhos (Oryctolagus cuniculus) submetidos à ostectomia parcial do rádio

Bone trauma triggers an acute inflammatory response, which can alter the serum concentration of acute-phase proteins (PFA). We aimed to evaluate the effectiveness of PFA measurement as a laboratory biomarker for inflammation related to bone regeneration. A partial ostectomy of the right radius was performed on 22 young male rabbits. The complete blood count, albumin, ceruloplasmin, haptoglobin, C-reactive protein, and transferrin levels were recorded and correlated with the radiographic evolution of bone healing. Statistically the best correlations with the inflammatory process and radiological findings were reported with haptoglobin and transferrin compared to the other measured PFAs. Haptoglobin and transferrin showed a maximum peak 24 and 36 hours after surgery, respectively. Transferrin displayed signs of decrease in the first 6 hours after surgery, in advance of the leukocyte response. The measurement of acute-phase proteins proved to be viable, considering the conditions in which the present study was carried out. Among all variables studied, haptoglobin and transferrin showed best correlation with the inflammatory process of bone healing. Additional studies are needed to determine the sensitivity of acute-phase proteins as predictors of complications in the treatment of fractures.(AU)

Os traumas ósseos desencadeiam resposta inflamatória aguda e consequentemente alteram a concentração sérica das proteínas de fase aguda (PFA), podendo essas representarem um parâmetro para avaliação da evolução do processo inflamatório relacionado à cicatrização óssea, assim como complicações. Objetivou-se avaliar a inter-relação da mensuração de PFAs com a repação óssea em coelhos submetidos à ostectomia parcial do rádio. Foram utilizados 22 coelhos, machos, jovens (160 a 180 dias) e peso médio (3,8 ± 0,3). Para acompanhamento da evolução do processo inflamatório foram realizados hemograma completo e mensuração de albumina, ceruloplasmina, haptoglobina, proteína C reativa e transferrina, além do acompanhamento radiológico. Foi observado a melhor correlação da haptoglobina e da transferrina junto ao processo inflamatório e achados radiológicos frente às demais PFAs mensuradas. A haptoglobina apresentou pico máximo 24 horas do pós-operatório e a transferrina após 36 horas, entretanto, essa última já mostrou indícios de diminuição nas primeiras 6 horas do pós-cirúrgico, antecipadamente à resposta leucocitária. Nas condições em que o presente estudo foi realizado, a mensuração das proteínas de fase aguda mostrou-se factível. Das proteínas estudadas, a haptoglobina e transferrina foram as que mostraram maior correlação com o processo inflamatório da cicatrização óssea. Estudos adicionais são necessários para determinar a sensibilidade das proteínas de fase aguda como previsores de complicações do tratamento das fraturas.(AU)
