Sex and slaughter weight on carcass traits and non-carcass components of horses / Sexo e peso de abate sobre as características de carcaça e componentes não-carcaça de cavalos

The study evaluated the effect of sex and slaughter weight on carcass traits and non-carcass components of 1,489 horses (739 geldings and 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had a higher (P < 0.05) hot carcass yield (HCY) and cold carcass yield (CCY) than females; however, fat yellowness values (b*) were greater (P < 0.05) in females. Slaughter weight (SW) affected the carcass characteristics. Hot carcass weight (HCW), cold carcass weight (CCW), HCY, and CCY increased (P < 0.05) in accordance with slaughter weight, while cool loss percentage (CL%) was lower (P < 0.05) in horses weighing more than 300 kg. In addition, the non-carcass components decreased (P < 0.05) as the weight of the horses increased. In conclusion, sex and body weight are factors to consider in the production of equine meat since they affect carcass characteristics and non-carcass components.

O estudo teve como objetivo avaliar o efeito do sexo e do peso ao abate sobre as características de carcaça e componentes não-carcaça de 1.489 cavalos (739 machos castrados e 750 fêmeas, classificados em oito grupos de acordo com o peso). Os dados foram analisados em um desenho inteiramente casualizado. Os semeadores apresentaram maior rendimento de carcaça quente (HCY) e fria (CCY) do que as fêmeas, porém o amarelecimento da gordura (b*) foi maior nas fêmeas. O peso ao abate (SW) afetou as características de carcaça. HCW, CCW, HCY e CCY aumentaram de acordo com o peso de abate, enquanto CL% foi menor em equinos com peso superior a 300 kg. Além disso, os componentes não-carcaça diminuíram com o aumento do peso dos cavalos. Em conclusão, sexo e peso corporal são fatores a serem considerados na produção de carne equina, uma vez que afetam as características da carcaça e seus componentes.

Milk supplementation: effect on piglets performance, feeding behavior and sows physiological condition during the lactation period

The present study aimed to investigate the effect of milk liquid and powder supplements on piglets' performance, drinking behavior, and sow back-fat thickness change during the lactation period. There were four experimental groups (n = 24), and in the control group (n = 6), the piglets were suckled from the sow. For the supplemental groups (n = 18), milk powder (MP), milk liquid by feeding trough (MLFT), and milk liquid feeding by the bucket (MLFB). Data were collected with the weight of a total of 252 piglets measured at birth, at 14 days and at weaning (28 days), respectively. Sow back-fat thickness was measured 3 days before farrowing, 14 days after farrowing and at weaning. There were significant differences in average daily weight gain between day 14 and weaning age for the MP and MLFT (P < 0.05) but not in MLFB (P > 0.05). For approaches to the feeder, there were significantly higher in MP and MLFT groups (P < 0.05). Based on the examination of sow back-fat thickness, the back-fat loss was minimal (P < 0.05) in the MP and MLFT compared to the MLFB and the control. Giving the milk supplement as powder and liquid by feeding trough has increased the piglets' average daily gain and body weight on day 14th and the weaning day. Moreover, the back-fat thickness reduction of sows in the supplemental groups is lower compared to the control group.

Cell therapy with adipose tissue-derived human stem cells in the urinary bladder improves detrusor contractility and reduces voiding residue / A terapia celular com células-tronco humanas derivadas do tecido adiposo na bexiga urinária melhora a contratilidade do detrusor e reduz o resíduo miccional

Detrusor hypocontractility (DH) is a disease without a gold standard treatment in traditional medicine. Therefore, there is a need to develop innovative therapies. The present report presents the case of a patient with DH who was transplanted with 2 x 106 adipose tissue-derived mesenchymal stem cells twice and achieved significant improvements in their quality of life. The results showed that cell therapy reduced the voiding residue from 1,800 mL to 800 mL, the maximum cystometric capacity from 800 to 550 mL, and bladder compliance from 77 to 36.6 mL/cmH2O. Cell therapy also increased the maximum flow from 3 to 11 mL/s, the detrusor pressure from 08 to 35 cmH2O, the urine volume from 267 to 524 mL and the bladder contractility index (BCI) value from 23 to 90. The International Continence on Incontinence Questionnaire - Short Form score decreased from 17 to 8. Given the above, it is inferred that the transplantation of adipose tissue-derived mesenchymal stem cells is an innovative and efficient therapeutic strategy for DH treatment and improves the quality of life of patients affected by this disease.

Nutrient compositional variation and interrelationship in the muscle of wild and plastic-reared brachyuran

Edible brachyurans are recognized as a popular source of food due to their delicious taste and nutritional quality. This study investigated the nutrient compositional variation and interrelationship in the muscle of wild and plastic-reared Cardisoma armatum. The plastic-reared crab had 27.81 ± 2.29 g 100 g-1protein while crab from the wild contained 22.45 ± 2.65 g 100 g-1protein. The difference in protein content of plastic-reared and its counterpart from the mangrove swamp was not significantly different(p > 0.05). This is also true of other proximate composition except that wild crabs were slightly higher in both crude fat (2.68 ± 0.35 g 100 g-1) and carbohydrate (5.89 ± 3.05 g 100 g-1). Generally, the total energy contributed due to protein, carbohydrate and fat in the tissues of both wild and plastic-reared C. armatumare similar. In the wild crab, contents of calcium (16083.27 ± 2127.90 mg 100 g-1) and phosphorus (1191.42 ± 199.21) were relatively higher, while contents of magnesium (368.69 ± 111.05 mg 100 g-1), sodium (125.30 ± 11.18 mg 100 g-1) and potassium (87.36 ± 7.27 mg 100 g-1) were relatively higher inplastic-reared crabs. All significant mineral ratios in wild and plastic-reared C. amartumfall within acceptable range. The positive relationship in the nutritional quality indicates that changes in proximate composition are associated with changes in mineral contents of the crab tissue.(AU)

Use of multi-strain probiotics in linseed meal based diet for Labeo rohita fingerlings

Abstract Unavailability of probiotics in fish digestive system fingerlings is unable to digest and absorb their food properly. The current research was conducted to investigate the influence of probiotics added Linseed meal based (LMB) diet on hematology and carcass composition of Labeo rohita juveniles. Hematological parameters are essential diagnostics used to estimate the health status of fish. The usage of probiotics for fish health improvement is becoming common due to the higher demand for environment-friendly culture system in water. Linseed meal was used as a test ingredient to prepare six experimental test diets by adding probiotics (0, 1, 2, 3, 4 and 5 g/kg) and 1% indigestible chromic oxide for seventy days. According to their live wet weight, five percent feed was given to fingerlings twice a day. Fish blood and carcass samples (Whole body) were taken for hematological and carcass analysis at the end of the experiment. The highest carcass composition (crude protein; 18.72%, crude fat; 8.80% and gross energy; 2.31 kcal/g) was observed in fish fed with test diet II supplemented with probiotics (2 g/kg). Moreover, maximum RBCs number (2.62× 106mm-3), WBCs (7.84×103mm-3), PCV (24.61), platelets (63.85) and hemoglobin (7.87) had also been reported in the fish fingerlings fed on 2 g/kg of probiotics supplemented diet. Results indicated that probiotics supplementation has a critical role in improvement of fingerlings body composition and hematological indices. Present findings showed that probiotics supplementation at 2 g/kg level in linseed by-product-based diet was very useful for enhancing the overall performance of L. rohita fingerlings.

Resumo A indisponibilidade de probióticos em alevinos do sistema digestivo de peixes faz com que ele seja incapaz de digerir e absorver seus alimentos adequadamente. A presente pesquisa foi conduzida para investigar a influência de probióticos adicionados à dieta à base de farelo de linhaça (LMB) na hematologia e na composição da carcaça de juvenis de Labeo rohita. Os parâmetros hematológicos são diagnósticos essenciais usados para estimar o estado de saúde dos peixes. O uso de probióticos para a melhoria da saúde dos peixes está se tornando comum devido à maior demanda por sistemas de cultivo em água que não agridam o meio ambiente. Farinha de linhaça foi usada como ingrediente para preparar seis dietas de teste experimentais adicionando probióticos (0, 1, 2, 3, 4 e 5 g/kg) e 1% de óxido crômico indigestível por 70 dias. De acordo com seu peso úmido vivo, 5% de alimento eram dados aos alevinos duas vezes ao dia. Amostras de sangue e carcaça de peixes (corpo inteiro) foram coletadas para análise hematológica e de carcaça no final do experimento. A maior composição da carcaça (proteína bruta, 18,72%; gordura bruta, 8,80%; e energia bruta, 2,31 kcal/g) foi observada em peixes alimentados com a dieta teste II suplementada com probióticos (2 g/kg). Além disso, os números máximos de RBCs (2,62×106 mm-3), WBCs (7,84×103 mm-3), PCV (24,61), plaquetas (63,85) e hemoglobina (7,87) também foram relatados em alevinos alimentados com 2 g/kg de dieta suplementada com probióticos. Os resultados indicaram que a suplementação de probióticos tem um papel crítico na melhoria da composição corporal dos alevinos e índices hematológicos. As descobertas atuais mostraram que a suplementação de probióticos no nível de 2 g/kg em dieta à base de subproduto de linhaça foi muito útil para melhorar o desempenho geral de alevinos de L. rohita.

A proposed new frame score system for Nellore cattle / Proposta de novo sistema de escore de estrutura corporal para bovinos Nelore

A new frame score system was developed for Nellore cattle, based upon ideal slaughter weights to achieve desired degrees of carcass fat cover. Data consisting of 688 complete records including sex, age, weight, hip height, and subcutaneous fat on growing Nellore cattle (190 males and 498 females) were obtained from the National Association of Breeders and Researchers (ANCP), Ribeirão Preto - SP, Brazil. Weight data were regressed on sex, age, hip height, and fat cover as covariates. Age was then fixed at 550 days and fat cover was set to 6 mm, and new equations for frame scores (1 to 11) in Nellore cattle were developed: FrameNellore (males) = -42.43 + 0.04919 × Age + 0.3368 × Height - 0.0003369 × Age × Height and FrameNellore (females) = -41.76 + 0.04919 × Age + 0.3368 × Height - 0.0003369 × Age × Height (Age and Height in days and cm, respectively). The Nellore equations resulted in average frame of 5.3, ranging from 2.3 to 7.7. Values were similar for males (5.4) and females (5.3). By contrast, previous equations gave higher values, that were very different between males and females. The new Nellore frame scores appear reasonable, particularly regarding body composition.(AU)

Um novo sistema de escore para estrutura corporal foi desenvolvido para bovinos Nelore, baseado em pesos de abate ideais para atingir os graus desejados de cobertura de gordura da carcaça. Dados de 688 registros completos incluindo sexo, idade, peso, altura do quadril e gordura subcutânea de bovinos Nelore em crescimento (190 machos e 498 fêmeas) foram obtidos da Associação Nacional de Criadores e Pesquisadores (ANCP), Ribeirão Preto - SP, Brasil. Os dados de peso foram regredidos por sexo, idade, altura do quadril e cobertura de gordura como covariáveis. A idade foi então fixada em 550 dias e a cobertura de gordura foi fixada em 6 mm, e novas equações para escores de estrutura corporal (1 a 11) em bovinos Nelore foram desenvolvidas: FrameNelore (machos) = -42,43 + 0,04919 × Idade + 0,3368 × Altura - 0,0003369 × Idade × Altura e FrameNellore (fêmeas) = -41,76 + 0,04919 × Idade + 0,3368 × Altura - 0,0003369 × Idade × Altura (Idade e Altura em dias e cm, respectivamente). As equações de Nelore resultaram em estrutura corporal médio de 5,3, variando de 2,3 a 7,7. Os valores foram semelhantes para machos (5,4) e fêmeas (5,3). Por outro lado, as equações anteriores deram valores mais altos, que eram muito diferentes entre machos e fêmeas. As novas pontuações de estruturacorporal no Nelore parecem razoáveis, principalmente em relação à composição corporal.(AU)

Carcass characteristics and meat quality of lambs fed diets with different roughage: concentrate ratios supplemented with liquid residue of cassava

The objective of this study was to evaluate the effects of lambs fed two roughage: concentrate (R:C) ratios, with or without the liquid residue of cassava (LRC) on carcass traits and meat quantity. Forty lambs (19.5 ± 1.45 kg body weight), non-castrated, crossbred Santa Inês were distributed in a completely randomized 2 × 2 factorial design. There was no effect (p > 0.05) of the inclusion of LRC on the variables. The roughage:concentrate ratio of 40:60 promoted higher values for empty body weight, hot carcass weight, cold carcass weight, subcutaneous thickness fat, cooling loss, Longissimus muscle area, carcass morphometric measurements, and commercial cuts. Higher weight of leg, muscles, fat, bone and other tissues, as well as for the ratio muscle:fat, and muscle:bone was observed in lambs fed 40R:60C. For the meat chemical composition, there was the effect (p < 0.05) only for ether extract (EE) for lambs fed 40R:60C ratio. The redness (a*) of meat was greater (p < 0.05) for lambs fed 80R:20C. The other physicochemical characteristics were not influenced. The roughage:concentrate ratio of 40:60 improves the carcass traits and commercial cuts, but does not promote changes in meat quality, independent of supplementation with liquid residue of cassava.(AU)

Efficacy of acidified phytase supplemented cottonseed meal based diets on growth performance and proximate composition of Labeo rohita fingerlings

Abstract The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p 0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

Resumo O crescimento do setor de aquicultura é fortemente dependente do fornecimento contínuo de rações baratas para peixes com perfil nutricional equilibrado. Porém, a farinha de peixe (FM) não consegue atender a essa demanda devido à sua escassa oferta e alto custo. Com o objetivo de testar o potencial da farinha de semente de canola (MSC) como substituto da farinha de peixe, um ensaio alimentar de 12 semanas foi conduzido para verificar o desempenho de crescimento e a composição centesimal de alevinos de Labeo rohita. A ração de proteína da ração teste foi satisfeita substituindo FM por CSM em 0, 25, 50 e 75%. Dezesseis dietas de teste, viz., TD1 (controle), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 e TD16 foram suplementadas com ácido cítrico (CA; 0 e 2,5%) e fitase (PHY; 0 e 750 FTU / kg) em um delineamento inteiramente casualizado com arranjo fatorial 3 × 3. O maior ganho de peso (11,03g), % de ganho de peso (249,21%), taxa de crescimento específico (1,39) e melhor taxa de conversão alimentar (1,20) foram registrados por peixes alimentados com TD12. Além disso, o mesmo nível aumentou a proteína bruta (59,26%) e a gordura (16,04%), sendo significativamente diferente (p 0,05) do controle. Conclusivamente, a adição de fitase acidificada (CA; 2,5%, PHY; 750 FTU / kg) em TD12 (CSM = 50%) levou a um melhor crescimento e composição próxima de alevinos de L. rohita.

Sex and slaughter weight on carcass traits and non-carcass components of horses / Sexo e peso de abate sobre as características de carcaça e componentes não-carcaça de cavalos

ABSTRACT: The study evaluated the effect of sex and slaughter weight on carcass traits and non-carcass components of 1,489 horses (739 geldings and 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had a higher (P < 0.05) hot carcass yield (HCY) and cold carcass yield (CCY) than females; however, fat yellowness values (b*) were greater (P < 0.05) in females. Slaughter weight (SW) affected the carcass characteristics. Hot carcass weight (HCW), cold carcass weight (CCW), HCY, and CCY increased (P < 0.05) in accordance with slaughter weight, while cool loss percentage (CL%) was lower (P < 0.05) in horses weighing more than 300 kg. In addition, the non-carcass components decreased (P < 0.05) as the weight of the horses increased. In conclusion, sex and body weight are factors to consider in the production of equine meat since they affect carcass characteristics and non-carcass components.

RESUMO: O estudo teve como objetivo avaliar o efeito do sexo e do peso ao abate sobre as características de carcaça e componentes não-carcaça de 1.489 cavalos (739 machos castrados e 750 fêmeas, classificados em oito grupos de acordo com o peso). Os dados foram analisados em um desenho inteiramente casualizado. Os semeadores apresentaram maior rendimento de carcaça quente (HCY) e fria (CCY) do que as fêmeas, porém o amarelecimento da gordura (b*) foi maior nas fêmeas. O peso ao abate (SW) afetou as características de carcaça. HCW, CCW, HCY e CCY aumentaram de acordo com o peso de abate, enquanto CL% foi menor em equinos com peso superior a 300 kg. Além disso, os componentes não-carcaça diminuíram com o aumento do peso dos cavalos. Em conclusão, sexo e peso corporal são fatores a serem considerados na produção de carne equina, uma vez que afetam as características da carcaça e seus componentes.

The Effect of Moringa Oleifera Leaf and Canola Seed Powder on Fattening, Laying Performance, Blood Plasma Constituents, and Microbiota in Japanese Quails

The aim of the study was to investigate the effect of feeding Japanese quail chicks with diets containing different levels of Moringa oleifera leaf and canola seed powder on growth performance, carcass yield, blood plasma constituents, and egg production. The trial lasted for a total of 7 weeks, with 5 weeks of fattening and two weeks of laying. The first group was the control group, while the second group was supplemented with Moringa oleifera leaves (4g/kg diet), the third group was supplemented with canola seed powder (4g/kg diet), the fourth group was supplemented with a mix of Moringa oleifera leaves and canola seed powder (8g/kg diet). The results showed that canola seed powder from 0-3 weeks of age increased body weight in comparison to the control group, but there were no significant differences (p<0.05) among groups in terms of the final body weight and feed conversion ratio. Average daily feed intake was significantly different (p<0.05). However, body weight, carcass weight, liver weight, gizzard weight, and abdominal fat weight increased significantly compared to the control group. Feeding Moringa oleifera leaves and canola seed powder significantly increased the total plasma protein, as compared to the control group. There were significant decreases in cholesterol, triglycerides and HDL levels among groups, with no significant differences in glucose, ALT and LDL among all treatments. The addition of Moringa oleifera leaf and canola seed powder showed significant effects on calcium and magnesium. Both Moringa oleifera leaf and Moringa-canola mixture significantly reduced the presence of some pathogenic bacteria in the digestive system, which was seen as an important contribution to the digestive and immune systems.(AU)

Effect of heat stress and solar radiation on dry matter intake, biochemical indicators, production, and quality of Holstein and Jersey cows' milk / Efeito do estresse calórico e da insolação sobre consumo, indicadores bioquímicos, produção e qualidade do leite de vacas Holandês e Jersey

The objective of this work was to compare the dry matter intake, milk yield and quality, physiological and biochemical parameters in Holstein (n=10) and Jersey (n=10) cows under heat stress and insolation, in two treatments: CL - cooling by ventilation and sprinkling and HS - heat stress and insolation. Data were submitted to ANOVA. There was an interaction between treatment and breed and day effect for dry matter intake. For consumption in % of body weight, CL and Jersey cows consumed more. CL cows produced more milk and 3.5% fat-corrected milk. Feed efficiency was similar between treatments and breeds. Fat, lactose, total solids, and somatic cell score did not differ. The concentration of milk urea nitrogen was higher for CL cows. Milk from Holstein cows had greater stability to alcohol, and from HT cows had a greater freezing point of milk. HT cows had higher respiratory rates in the morning and surface temperatures in the afternoon. There were no differences in beta-hydroxybutyrate and glucose concentrations. Heat stress, with insulation, reduces intake, especially in Holstein cows, as well as milk production and increases the freezing point of milk, respiratory rate, and surface temperature.

O objetivo deste trabalho foi comparar o consumo de matéria seca, a produção e a qualidade do leite, os parâmetros fisiológicos e bioquímicos em vacas das raças Holandesa (n=10) e Jersey (n=10) sob estresse calórico e insolação, em dois tratamentos: CL - resfriamento por ventilação e aspersão; HS - estresse térmico e insolação. Os dados foram submetidos à análise de variância. Houve interação entre tratamento e raça e efeito de dia para consumo de matéria seca. Para consumo em % de peso vivo, vacas CL e Jersey consumiram mais. Vacas CL produziram mais leite e leite corrigido a 3,5% de gordura. A eficiência alimentar foi similar entre tratamentos e raças. Teores de gordura, lactose, sólidos totais e escore de células somáticas não diferiram. A concentração de nitrogênio ureico do leite foi maior para vacas CL. O leite das vacas Holandesas apresentou maior estabilidade ao álcool, e de vacas HT maior crioscopia. Vacas HT apresentaram maior frequência respiratória de manhã e temperatura superficial à tarde. Não houve diferenças para concentração de beta-hidroxibutirato e glicose. O estresse calórico, com insolação, reduz o consumo, especialmente em vacas Holandesas, bem como a produção de leite, com aumento da crioscopia, elevando a frequência respiratória e a temperatura superficial.

Commercial Feed Diluted with Different Fiber Sources and Enzyme Product for Broilers: Growth Performance, Carcass and Gut Health

The dilution of commercial broiler feed with copra meal (CM), palm kernel meal (PKM) and cassava leaf meal (CLM) and enzyme supplementation was investigated. Two hundred and eighty 7-day old Cobb 500 broilers were fed commercial feed alone or diluted with the test ingredients with and without enzyme. There were no interaction effects (p>0.05) on feed intake (FI) and weight gain (WG). Poorer (p<0.05) feed conversion ratio (FCR) was observed on the diet diluted diets from 22-42 d, but this was restored (p>0.05) by enzyme supplementation. There was no interaction effect on final body weight (FBW). Diet dilution depressed FBW (p<0.05) but enzyme supplementation restored (p>0.05) this weight depression. Abdominal fat was lighter (p<0.05) on CLM compared to CM. There were no interaction effects (p>0.05) on the weight of gut segments and E. coli count. Heavier (p<0.05) liver, gizzard and intestine were observed on the test diets. Commercial feed dilution with CM, CLM and PKM at 100 g/kg for starter and 200 g/kg for finisher would be a viable option for smallholder broiler production. More research is needed into dilution levels and enzyme concentrations.(AU)

Farinha de linhaça foi usada como ingrediente para preparar seis dietas de teste experimentais adicionando probióticos (0, 1, 2, 3, 4 e 5 g/kg) e 1% de óxido crômico indigestível por 70 dias. De acordo com seu peso úmido vivo, 5% de alimento eram dados aos alevinos duas vezes ao dia. Amostras de sangue e carcaça de peixes (corpo inteiro) foram coletadas para análise hematológica e de carcaça no final do experimento. A maior composição da carcaça (proteína bruta, 18,72%; gordura bruta, 8,80%; e energia bruta, 2,31 kcal/g) foi observada em peixes alimentados com a dieta teste II suplementada com probióticos (2 g/kg). Além disso, os números máximos de RBCs (2,62×106 mm-3), WBCs (7,84×103 mm-3), PCV (24,61), plaquetas (63,85) e hemoglobina (7,87) também foram relatados em alevinos alimentados com 2 g/kg de dieta suplementada com probióticos. Os resultados indicaram que a suplementação de probióticos tem um papel crítico na melhoria da composição corporal dos alevinos e índices hematológicos. As descobertas atuais mostraram que a suplementação de probióticos no nível de 2 g/kg em dieta à base de subproduto de linhaça foi muito útil para melhorar o desempenho geral de alevinos de L. rohita.

Use of multi-strain probiotics in linseed meal based diet for Labeo rohita fingerlings / Uso de probióticos multi-cepas na dieta à base de farinha de linhaça para alevinos de Labeo rohita

Unavailability of probiotics in fish digestive system fingerlings is unable to digest and absorb their food properly. The current research was conducted to investigate the influence of probiotics added Linseed meal based (LMB) diet on hematology and carcass composition of Labeo rohita juveniles. Hematological parameters are essential diagnostics used to estimate the health status of fish. The usage of probiotics for fish health improvement is becoming common due to the higher demand for environment-friendly culture system in water. Linseed meal was used as a test ingredient to prepare six experimental test diets by adding probiotics (0, 1, 2, 3, 4 and 5 g/kg) and 1% indigestible chromic oxide for seventy days. According to their live wet weight, five percent feed was given to fingerlings twice a day. Fish blood and carcass samples (Whole body) were taken for hematological and carcass analysis at the end of the experiment. The highest carcass composition (crude protein; 18.72%, crude fat; 8.80% and gross energy; 2.31 kcal/g) was observed in fish fed with test diet II supplemented with probiotics (2 g/kg). Moreover, maximum RBCs number (2.62× 106mm-3), WBCs (7.84×103mm-3), PCV (24.61), platelets (63.85) and hemoglobin (7.87) had also been reported in the fish fingerlings fed on 2 g/kg of probiotics supplemented diet. Results indicated that probiotics supplementation has a critical role in improvement of fingerlings' body composition and hematological indices. Present findings showed that probiotics supplementation at 2 g/kg level in linseed by-product-based diet was very useful for enhancing the overall performance of L. rohita fingerlings.(AU)

Anestesia intravenosa parcial (AIVP) em uma lobo-guará (Chrysocyon brachyurus) neonata / Partial intravenous anesthesia (PIVA) in a neonate maned wolf (Chrysocyon brachyurus)

Background: The maned wolf (Chrysocyon brachyurus) is the largest canid in South America and the only representative of its genus. The scientific literature presents studies referring to the management and anaesthesia of the species but is scarce in case of emergency procedures, and to date, there are no reports of anaesthesia for emergency procedures in a neonatal maned wolf. Thus, this study aimed to report xenotransfusion and emergency anaesthesia for thoracic limb amputation in an approximately 8-days-old maned wolf pup. Case: A maned wolf pup, approximately 8-day-old, with a history of an accident with an agricultural machine, was referred to the Veterinary Hospital of the Federal University of Paraná - Palotina Sector (HVP - UFPR) with a grade III open fracture of left radius and ulna. At the physical evaluation, bullous rales were observed in the right caudal lobe on pulmonary auscultation, hypoglycemia and severe dehydration, the latter being determined by the occurrence of enophthalmos, increased capillary refill time and skin turgor (3 s). The hemogram revealed regenerative hypochromic macrocytic anaemia, thrombocytopenia and leukopenia, and the chest radiograph showed alveolar pattern opacification, associated with the presence of air bronchograms in the caudal lobes, more evident on the right side, suggestive of pulmonary contusion. Considering the laboratory alterations and the need for amputation of the thoracic limb, xenotransfusion was chosen before the anaesthetic procedure. The animal was pre-medicated with methadone 0.2 mg/kg and anaesthetic induction was performed with propofol titrated to effect, requiring 10 mg/kg. This was followed by endotracheal intubation and anaesthetic maintenance using the partial intravenous technique with an infusion of 5 µg/kg/h of remifentanil and Isoflurane vaporised through a non-rebreathing system in oxygen at 0.6. Anaesthetic monitoring included heart rate and electrocardiogram tracing, respiratory rate, oxyhemoglobin saturation, end-tidal partial pressure of carbon dioxide, systemic blood pressure by the oscillometric method, and oesophageal body temperature. Although the blood tests after the transfusion showed an increase in hematocrit, changes suggestive of a delayed hemolytic reaction because of the transfusion were also noticed. Discussion: Preanesthetic stabilisation is critical, as anaesthesia of unstable patients may result in a higher risk of anaesthetic complications. Critically ill patients may present systemic imbalances that can trigger pharmacokinetic and pharmacodynamic changes of anaesthetics and analgesics. Neonates have several marked physiological differences, since some organs are still immature, have a high body volume of water, and present a reduced amount of total fat and concentrations of circulating proteins, making it necessary to adjust protocols and doses used for these patients. Blood transfusion between the same species is always the best option, though xenotransfusion becomes an option when there is no homologous donor available. However, it can present a great risk to life, as there is a lack of studies regarding the blood typing of the species and blood compatibility tests. We concluded that there was an increase in hematocrit after 24 h of xenotransfusion and, even with signs of delayed hemolytic reaction observed in the blood test, the patient did not show specific clinical signs of transfusion reaction. The pup was sensitive to methadone but required a high dose of propofol for anaesthetic induction. The use of methadone as a pre-anaesthetic agent and the infusion of remifentanil provided adequate analgesia based on the parameters evaluated.

Extruded urea could replace true protein source in supplements for lambs finished in tropical pastures / A ureia extrusada pode substituir a fonte de proteína verdadeira em suplementos para cordeiros terminados em pastagens tropicais

The aim of this study was to evaluate the effects of replacing 50% of the true protein from soybean meal with extruded urea on the performance and carcass characteristics of lambs finished on pasture. Twenty lambs with initial weight of 29.9±6.2kg and 5 months of age, distributed in two treatments in blocks at random, were kept in pastures of Urochloa spp. Supplemented with 2% of body weight (BW). The treatments consisted of supplements containing soybean meal as the only true protein source (control), or extruded urea replacing 50% of soybean meal (NPN treatment). There was no effect of treatment on total supplement intake. There were differences in average daily gain (242.1 vs. 264.6g/day), slaughter weight (41.9 vs. 45.0kg) and carcass weight (18.9 vs. 20.1kg). There was no effect of the treatment on the final body condition score, hot carcass yield, carcass length, breast depth, subcutaneous fat thickness or rib eye area. The group of animals that received extruded urea showed superior carcass finishing characteristics (99.0% vs. 66.0%), maturity (22.0% vs. 0.0%), marbling (55.0% vs. 33.0%), meat texture (44.0% vs. 33.0%) and fat (66.0% vs. 22.0%). There were no significant effects on tenderness (7.5kg/f) or flesh color (L* = 33.2; a* = 16.2; b* = 8.3). There were no significant changes in the biochemical profile of the animals' blood during the experiment for both treatments. The replacement of 50% of protein from soybean meal by the extruded urea as NPN source in the supplement for lambs finished in Urochloa spp pastures provides better animal performance and qualitative characteristics of meat, without altering quantitative carcass characteristics.

Objetivou-se avaliar os efeitos da substituição de 50% da proteína verdadeira do farelo de soja por ureia extrusada sobre o desempenho e as características de carcaça de cordeiros terminados em pasto. Vinte cordeiros de 29,9+6,2kg de peso inicial e com cinco meses de idade, distribuídos em dois tratamentos em blocos ao acaso, foram mantidos em pastagens de Urochloa spp. suplementado com 2% do peso vivo (PV). Os tratamentos consistiram em suplementos contendo farelo de soja como única fonte de proteína verdadeira (controle), ou ureia extrusada em substituição a 50% do farelo de soja (tratamento NPN). Não houve efeito do tratamento na ingestão total de suplemento. Houve diferenças no ganho médio diário (242,1 vs. 264,6 g/dia), no peso ao abate (41,9 vs. 45,0kg) e no peso da carcaça (18,9 vs. 20,1kg). Não houve efeito do tratamento sobre escore de condição corporal final, rendimento de carcaça quente, comprimento de carcaça, profundidade do peito, espessura de gordura subcutânea ou área de olho de lombo. O grupo de animais que recebeu ureia extrusada apresentou características superiores de acabamento de carcaça (99,0% vs. 66,0%), maturidade (22,0% vs. 0,0%), marmoreio (55,0% vs. 33,0%), textura da carne (44,0% vs. 33,0%) e gordura (66,0% vs. 22,0%). Não houve efeitos significativos na maciez (7,5 kg/f) nem na cor da carne (L*= 33,2; a*= 16,2; b * = 8,3). Não houve mudanças significativas no perfil bioquímico do sangue dos animais durante o experimento para ambos os tratamentos. A substituição de 50% da proteína do farelo de soja pela ureia extrusada como fonte de NPN no suplemento para cordeiros terminados em pastagem de Urochloa spp. proporciona melhor desempenho animal e características qualitativas da carne, sem alterar as características quantitativas da carcaça.

Efficacy of acidified phytase supplemented cottonseed meal based diets on growth performance and proximate composition of Labeo rohita fingerlings / Eficácia de dietas à base de algodão com fitase acidificada suplementada no desempenho do crescimento e na composição proximada de dedos de Labeo rohita

The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

O crescimento do setor de aquicultura é fortemente dependente do fornecimento contínuo de rações baratas para peixes com perfil nutricional equilibrado. Porém, a farinha de peixe (FM) não consegue atender a essa demanda devido à sua escassa oferta e alto custo. Com o objetivo de testar o potencial da farinha de semente de canola (MSC) como substituto da farinha de peixe, um ensaio alimentar de 12 semanas foi conduzido para verificar o desempenho de crescimento e a composição centesimal de alevinos de Labeo rohita. A ração de proteína da ração teste foi satisfeita substituindo FM por CSM em 0, 25, 50 e 75%. Dezesseis dietas de teste, viz., TD1 (controle), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 e TD16 foram suplementadas com ácido cítrico (CA; 0 e 2,5%) e fitase (PHY; 0 e 750 FTU / kg) em um delineamento inteiramente casualizado com arranjo fatorial 3 × 3. O maior ganho de peso (11,03g), % de ganho de peso (249,21%), taxa de crescimento específico (1,39) e melhor taxa de conversão alimentar (1,20) foram registrados por peixes alimentados com TD12. Além disso, o mesmo nível aumentou a proteína bruta (59,26%) e a gordura (16,04%), sendo significativamente diferente (p <0,05) do controle. Conclusivamente, a adição de fitase acidificada (CA; 2,5%, PHY; 750 FTU / kg) em TD12 (CSM = 50%) levou a um melhor crescimento e composição próxima de alevinos de L. rohita.

Tumor neuroendócrino em coração de cão / Neuroendocrine tumor involving the heart of a dog

Background: Neuroendocrine tumors are epithelial tumors with predominant neuroendocrine differentiation. Ectopic thyroid carcinoma develops in the ectopic thyroid parenchyma, in the anterior mediastinum, being an important differential diagnosis of paraganglioma, although occurring less frequently than the same. The cells invade the mediastinal fat reaching the adventitia of the aorta. There is a possibility of metastatic formations in the lung, kidneys, and pancreas. A supporting treatment was provided. The present study proposes the exposition and description of a case of neuroendocrine tumor in the heart, considering the rarity of the involvement of this tumor in the canine species. Case: A 9-year-old American Bulldog male canine was treated at home in the city of Rio de Janeiro. On clinical examination, dyspnea, edema of the hind limbs and an increase in abdominal volume were observed. With the suspicion of congestive heart failure, mainly on the right, cardiac exams were requested. Because it was an aggressive animal, sedation was performed with a combination of tiletamine and zolazepam. During cardiac auscultation, the presence of S4 was noticed, characterizing a gallop rhythm. No alterations were observed on the electrocardiographic examination. The echocardiogram showed a tumor mass in the atrium and dilation of the venous return vessels. The tumor enveloped 80% of the atrium of a 9-year-old male American Bulldog. The abdominocentesis procedure was performed to drain abdominal free fluid. Furosemide, enalapril and digoxin were prescribed as a treatment. Three months after the start of treatment, the animal presented intense dyspnea that culminated in the death of the patient, who later had the body sent for necropsy and subsequent tissue collection for histopathological analysis. Based on the immunohistochemical markers chromogranin and synaptophysin, the work here presented describes a case of a neuroendocrine tumor suggestive of paraganglioma involving a dog's heart. Discussion: Brachycephalic dogs, such as Boxers, Bulldogs and Boston Terriers, are predisposed to the development of paragangliomas. The genetic predisposition is related to hyperplasia of the carotid bodies generated by chronic hypoxia, resulting from obstructive processes in the airways. As the reported dog is an American Bulldog, the possibility of the tumor in question was reinforced. Paragangliomas are more frequent in males from nine to thirteen years of age, commonly associated with other endocrine neoplasms. It is also an important marker present in paragangliomas. In contrast to the literature, the report points to a neuroendocrine tumor suggestive of paraganglioma, without eliminating the possibility of an ectopic thyroid tumor, because although TTF-1 appears in most thyroid tumors, not all of them are present, although it is very suggestive. Treatment in question, attributed to the control of right congestive heart failure, although with little effect, denotes that the obstructive process of the return pathway, even with the use of drugs that prevent congestion, did not delay the evolution of the disease. However, it is observed that the treatment resources for these tumors, whether by surgical or chemotherapy option, also have few answers. The lack of literature on ectopic thyroid tumors influences the diagnosis of paraganglioma. Thus, clinical and complementary findings, mainly along with immunohistochemistry, were essential in the diagnosis of neuroendocrine tumor. After 3 months of the start of the treatment, the animal died.
