Clinical and epidemiological findings of cecal disorders in horses in the state of Paraíba / Achados clínicos e epidemiológicos dos distúrbios cecais em cavalos no estado da Paraíba

This was a retrospective case study of colic syndrome of cecal origin in 159 horses treated at a reference Veterinary Center between June 2015 and July 2021. The data studied were breed, age, sex, clinical examinations of the initial emergency care, treatment protocols (clinical and/or surgical) and resolution (hospital discharge, euthanasia or death). It was observed that 7.55% (n = 12) of the cases corresponded to colic syndrome of cecal origin, where 75% (n = 9) had heart rate within the physiological range for the species, as well as 50% (n = 6) for capillary refill time values, 33.33% (n = 4) for pink mucosa, 41.67% (n = 5) for rectal temperature, and 16.67% (n = 2) on abdominal auscultation. In 58.34% (n = 7) of patients, pain could be controlled with analgesics, with recurrence in 41.67% (n = 5). All treated cases were cecal impaction, where 58.33% (n = 7) ruptured the cecum. In 75% (n = 9) of the cases, surgical treatment was performed. Regarding the general resolution of cases, 41.67% (n = 5) of the animals were discharged. Therefore, it is concluded that despite the increase in the diagnosis of colic of cecal origin, this disease is still rare (7.55%) and has a high potential for death since there are few clinical alterations, making its early diagnosis difficult.(AU)

Este foi um estudo retrospectivo dos casos de síndrome cólica de origem cecal em 159 cavalos atendidos em um Centro Veterinário de referência entre junho de 2015 e julho de 2021. Os dados estudados foram raça, idade, sexo, exames clínicos do atendimento inicial de emergência, protocolos de tratamento (clínico e/ou cirúrgica) e resolução (alta hospitalar, eutanásia ou óbito). Observou-se que 7,55% (n = 12) dos casos correspondiam à síndrome cólica de origem cecal, onde 75% (n = 9) apresentavam frequência cardíaca dentro da faixa fisiológica para a espécie, assim como 50% (n = 6) para valores de tempo de enchimento capilar, 33,33% (n = 4) para mucosa rosada, 41,67% (n = 5) para temperatura retal e 16,67% (n = 2) para ausculta abdominal. Em 58,34% (n = 7) dos pacientes, a dor pôde ser controlada com analgésicos, com recidiva em 41,67% (n = 5). Todos os casos tratados foram de impactação cecal, onde 58,33% (n = 7) romperam o ceco. Em 75% (n = 9) dos casos, o tratamento cirúrgico foi realizado. Em relação à resolução geral dos casos, 41,67% (n = 5) dos animais tiveram alta. Portanto, conclui-se que apesar do aumento do diagnóstico de cólica de origem cecal, esta enfermidade ainda é rara (7,55%) e apresenta um alto potencial de óbito visto que há poucas alterações clínicas dificultando seu diagnóstico precoce.(AU)

Síndrome cólica em equinos induzida por ingestão de cana de açúcar / Equine colic syndrome induced by the ingestion of sugarcane

Background: Equine colic syndrome comprises numerous conditions associated with abdominal pain in horses. Impaction, a common cause of this manifestation, is strongly related to these animals' diet. Highly fibrous diets such as sugarcane can predispose horses to colic. The clinical condition can be worsened by fermentative processes, which lead to dysbiosis, circulatory disorders and even endotoxemia. The aim of this study was to report 4 cases of colic syndrome among 8 horses that underwent an experiment to adapt them to a sugarcane-based diet, and to correlate the animals' clinical conditions to the forage they ingested. Cases: Eight male castrated Mangalarga Marchador horses, between 5.5 and 7 years old, were subjected to an experiment to test the feasibility of sugarcane as forage. Four of these horses were taken to the Large Animal Veterinary Hospital (HVGA) of the Federal Rural University of Rio de Janeiro for treatment of abdominal signs of discomfort a few days after the exclusive consumption of sugarcane, in a proportion of 1.75% of live weight in dry matter. The animals' symptoms ranged from behavioral signs indicative of pain to changes in vital parameters and structure of the feces, as well as changes revealed by transrectal palpation. Three of the 4 cases presented impaction in the small colon, and 1 of the horses also presented impaction in the right dorsal colon and rostral displacement of the pelvic flexure, with accumulation of contents in the right ventral colon and sternal flexure. Two of the cases were treated medically, while the other 2 required surgical intervention. The clinical condition of all the patients evolved favorably and they were discharged between 2 and 18 days. Discussion: Colic originating in the digestive system is a syndrome strongly associated with management, especially with respect to confinement, nutrition, and parasite control. During the experiment, 4 of the 8 horses fed with sugarcane presented with colic syndrome. The low quality of sugarcane fiber is due to the high degree of lignification of the plant cell wall, which favors accumulation of ingesta. The poor digestibility and sweet taste of this roughage favor increased consumption. Furthermore, its high sucrose content, associated with an increased rate of passage in the small intestine, alters the intestinal microbiome, and hence, the fermentation byproducts and pH of the ingesta. High intestinal content, allied to longer retention times in the colon and activation of the renin-angiotensin-aldosterone system, promote greater dryness of the ingesta, predisposing the occurrence of impactions in the most distal portion of the large intestine. Intestinal distension and mesenteric traction caused by the accumulation of contents and gases trigger pain, which can worsen due to displacement of the large colon. Small colon impaction, which is easily identified by transrectal palpation, evolves gradually and its treatment, both clinical and surgical, tends to have a favorable prognosis. The need for alternative food sources for horses is a growing demand; however, sugarcane as an exclusive roughage has been shown to be unsafe for horses. The low quality of the fiber and the high sucrose content of this forage can alter the digestive physiology of horses through changes in the passage rate, microbiome and motility of digesta, predisposing them to intestinal dysfunction, ingesta compaction and displacement of the large colon.

Omentum as non-strangled inguino scrotal hernia content in stallion: case report / [Omento como conteúdo de hérnia inguino-escrotal não estrangulada em garanhão: relato de caso]

Non-strangulated acquired hernias in stallions are rare, especially when the herniated content is not intestinal loops. Thus, the aim of the current study is to describe a case of acquired non-strangulated inguinoscrotal hernia in a stallion, whose herniated content was the omentum. The patient was a Criollo stallion with history of rhabdomyolysis, laminitis and bilateral scrotal volume increase observed in the left scrotal region. The animal presented pain in both thoracic limbs, abnormal blood test, especially hypoproteinemia, and mild pain during palpation in the left inguinal ring region. Hydrocele secondary to hypoproteinemia was suspected. After admission, the animal showed signs of acute abdomen, which were clinically reversed. With this, the animal was subjected to ultrasound examination of the scrotal region, whose findings suggested non-strangulated inguinal hernia, although the content could not be identified. Surgical treatment was chosen in order to identify the herniated content and remove the left testicle. Access to the affected scrotum was performed, in which the presence of fluid and a portion of the omentum was observed surrounding the testis and adhering to it. The animal was discharged after he recovered from the surgery and from laminitis. During the breeding season, the stallion remained with a herd of mares for natural mating. After 15 months of surgery, the animal was reassessed and showed no active signs of inflammatory and degenerative processes in the remaining testis. On this occasion, a pregnancy diagnosis was also performed, and all the mares were pregnant. It is concluded that the presence of omentum as a herniated content does not represent a surgical emergency but can make the reproductive prognosis reserved. In addition, removal of the affected testicle can benefit the spermatogenesis of the remaining testicle.(AU)

As hérnias adquiridas não estranguladas em garanhões são raras, principalmente quando o conteúdo herniado não é de alças intestinais. Assim, o objetivo deste trabalho foi descrever um caso de hérnia inguino escrotal adquirida e não estrangulada em garanhão, cujo conteúdo herniado era composto pelo omento. Foi atendido um garanhão da raça Crioula com histórico de rabdomiólise, laminite e aumento de volume escrotal bilateral, evidenciado na região escrotal esquerda. O animal apresentava dor nos membros torácicos, alterações na avaliação sanguínea, destacando-se a hipoproteinemia, e demonstrava dor leve à palpação na região do anel inguinal esquerdo. Suspeitou-se de hidrocele secundária a hipoproteinemia. Após a internação, o animal apresentou sinais de abdômen agudo, revertidos clinicamente. Com isso, realizou-se ultrassonografia da região escrotal, cujos achados sugeriram hérnia inguinal não estrangulada, sem que o conteúdo pudesse ser identificado. Optou-se pelo tratamento cirúrgico, com o intuito de identificação do conteúdo herniado e remoção do testículo esquerdo. Foi realizado acesso à bolsa escrotal afetada, na qual se observou presença de líquido e de uma porção do omento envolvendo o testículo e aderido a ele. O animal recebeu alta após restabelecimento da cirurgia e da laminite. Na propriedade, durante temporada reprodutiva, o garanhão permaneceu com uma manada de éguas para realização de monta natural. Passados 15 meses da cirurgia, o animal foi reavaliado e não demonstrou sinais ativos de processo inflamatório e degenerativos no testículo remanescente. Nessa ocasião, também foi realizado diagnóstico de gestação e todas as éguas encontravam-se prenhes. Conclui-se que a presença de omento como conteúdo herniado não representa uma emergência cirúrgica, mas pode tornar o prognóstico reprodutivo reservado. Ainda, a remoção do testículo afetado pode trazer benefícios à espermatogênese do remanescente.(AU)

Primary gastric rupture in 20 horses from Midwestern Brazil: case report / Ruptura gástrica primária em 20 equinos no Centro-Oeste do Brasil: relato de caso

An 11-year (2007-2018) survey of epidemiological, clinical and pathological findings of horses with primary gastric rupture (PGR) was conducted. Twenty horses presented PGR, nine (45%) horses were clinically evaluated, eleven (55%) were sent dead, and all animals were necropsied. PGR contributed to a prevalence of 0.31% (9/2,868) of all equid attendances, 1.83% (9/491) of colic cases, and 4.1% (20/487) of all equid necropsies. Highly fermentable feed (n=7), gastric impaction (n=4), and perforating gastric ulcer (n=1) were the main causes of PGR; whilst eight horses presented idiopathic gastric rupture. Clinically evaluated horses were tachycardic, tachypneic, febrile, dehydrated, with increased abdominal tension, abnormal mucous membranes and reduced to absent intestinal borborygmi. Improper dietary management, such as the ingestion of low-quality roughage and highly fermentable feedstuffs were detected as the main factors associated with PGR in Midwestern Brazil. It is important to raise awareness in horse owners about proper feed management to minimize PGR.(AU)

Foi realizado um levantamento de 11 anos (2007-2018) dos achados epidemiológicos, clínicos e patológicos de equinos com ruptura gástrica primária (RGP). Vinte equinos apresentaram RGP, dos quais nove (45%) foram avaliados clinicamente e 11 (55%) foram enviados mortos, sendo todos os animais necropsiados. A RGP contribuiu com prevalência de 0,31% de todos os atendimentos de equídeos (9/2.868), 1,83% (9/491) dos casos de cólica, e 4,1% (20/487) das necropsias em equídeos. Alimentos altamente fermentáveis (n=7), compactação gástrica (n=4) e perfuração de úlcera gástrica (n=1) foram as principais causas de RGP, enquanto oito equinos tiveram ruptura gástrica idiopática. Os equinos avaliados clinicamente apresentaram-se taquicárdicos, taquipneicos, febris, desidratados, com mucosas anormais, aumento da tensão abdominal e motilidade intestinal reduzida. O manejo inadequado da dieta, como a ingestão de forragens de baixa qualidade e alimentos altamente fermentáveis, foi o principal fator de risco associado à RGP no Centro-Oeste do Brasil. É importante aumentar a conscientização dos proprietários de equinos sobre o manejo alimentar adequado para minimizar a RGP.(AU)

Epidemiology of colic syndrome in horses over 15 years of care / Epidemiologia da síndrome cólica em equinos ao longo de 15 anos de atendimento

Colic syndrome is a condition of great importance in equine production, a syndrome considered to be complex and multifactorial in nature. In this way epidemiological studies have been acting to contribute to the identification of risk factors in the development of wind power. This study evaluated the clinical epidemiology of the colic syndrome according to race, gender, diagnosis, affected segment, therapeutic decision and outcome of the cases treated at the Veterinary Hospital "Dr Halim Atique", interior of São Paulo.  The medical records of the animals assisted from January 2004 to July 2018, whose complaint was abdominal discomfort, were evaluated. Of the 535 animals, the most affected breed was the Quarter Horses (69.3%) followed by the Mangalarga (6.9%); females (53.1%) were more prone to the development of the syndrome. Compaction (28.8%), gastritis (11.8%), followed by gas distension (10.3%) were the most frequent changes; the affected segments being the stomach (21.9%), major colon (17.2%), and small intestine (15.7%). Clinical treatment (64.7%) was the most instituted and in the outcome of the cases, the discharge (77.4%) prevailed. The study presents data that can support epidemiological research in the area, assisting in the identification of causal and predictive factors for the colic syndrome.

Abdome agudo em cutias no nordeste do Brasil / Acute abdomen in agouti in Northeastern of Brazil

Este trabalho apresenta pela primeira vez relatos de abdome agudo em cutia (Dasyprocta aguti Linnaeus, 1758) criada em cativeiro no Centro de Multiplicação de Animais Silvestres (CEMAS), Mossoró, Rio Grande do Norte. Sabendo que no cativeiro o estresse, a concentração de organismos patogênicos e erros no manejo alimentar podem acarretar distúrbios gastrintestinais em animais silvestres, torna-se necessário a identificação das causas do óbito em animais criados nesta condição. Dessa forma, foi realizado em cinco cutias adultas, que vieram a óbito após apresentar quadro clínico de distensão e dor abdominal, inquietação como também prostração, o exame anatomopatológico, que consiste no exame externo do animal, abertura das cavidades torácica e abdominal e retirada dos órgãos, seguida de estudo macroscópico. Sendo possível diagnosticar como causa do abdome agudo e consequente óbito, vólvulo intestinal, isquemia intestinal por trombo na artéria mesentérica e obstrução do intestino por impactação alimentar.

This case presents for the first time reports of acute abdomen in red-rumped agouti (Dasyprocta aguti Linnaeus, 1758) raised in captivity at the Wild Animals Multiplication Center (CEMAS), Mossoró, Rio Grande do Norte. Knowing that in captivity stress, concentration of pathogenic organisms and errors in food management can lead to gastrointestinal disorders in wild animals, it is necessary to identify the causes of death in animals raised in this condition. Thus, it was performed in five adult women, who died after clinical presentation of distension and abdominal pain, restlessness as well as prostration, anatomopathological examination, which consists of the external examination of the animal, opening of the thoracic and abdominal cavities and withdrawal of the followed by macroscopic study. It is possible to diagnose as the cause of the acute abdomen and consequent death, intestinal volvulus, intestinal ischemia due to thrombus in the mesenteric artery and intestinal obstruction due to food impaction.

Bypass ileal seguido de tiflostomia no tratamento de abdomen agudo em equino / Ileal bypass followed by tiflostomy to treat acute abdomen in a horse

Background: Equine gastrointestinal colic cases represent one of the diseases with higher morbidity and mortality. Short and long term survivals are commonly correlated with the colic causes, being considered 50 % the survival rate of horses referred to surgery because of small intestine strangulative causes. The jejuno-caecostomy technique is recommended in cases of ileum necrosis or ischemia that indicates ileum removal. The survival rate after this procedure is low, being even lower than others common terminal-terminal enteroanastomoses. This study reports a case of jejuno-caecostomy followed by tiflopexy and tiflostomy performed in a colic horse. Case: A 12-year-old mare, mangalarga breed, with a history of acute abdomen during 18 h was referred to the FZEA-USP equine hospital. According to the owner, the animal suffered previous episodes of colic that had been solved without treatment. On this occasion, the owner, without veterinary advice, had administered 10 mL of flunixin meglumine, but the animal did not show improvement. During the examination, the patient presented tachycardia, tachypnea, toxemic mucosa, a large amount of enterogastric reflux, and it was possible to observe distended small intestine during rectal palpation. The horse was referred to surgery; it was possible to identify necrosis of the ileum and 30 cm of the aboral segment of the jejunum, caused by strangulation due to a pedunculated lipoma localized in the medial band of the caecum. Latero-lateral jejuno-caecostomy was performed between the medial and dorsal bands of the caecum, using polyglactin 910, nº 2.0, potassium penicillin 30.000 IU / kg, every 6 h, gentamicin 6.6 mg / kg, every 24 h, flunixin meglumine 1.1 mg / kg, every 12 h and maintenance fluid therapy were performed post operatively. The animal had ileus and severe enterogastric reflux for five days postoperatively, showing severe signs of endotoxemia, and parenteral hydration seemed to be not enough. So it was...

Torção esplênica primária em cão como causa atípica de abdômen agudo / Primary splenic torsion in dog as a cause of atypical acute abdomen

Background: A primary splenic torsion occurs when the organ rotates around its vascular pedicle in the absence of any other concomitant disease. The occurrence of primary splenic torsion is rare, with a prevalence lower than 1%. Splenic torsion is more often related to dilated gastric volvulus syndrome, and it has no clear etiology despite reports that associate it with congenital abnormalities or traumatic ruptures of the gastrosplenic or splenocolic ligaments. This study reports a case of splenic torsion in an American Pit Bull terrier dog, its related symptomatology, and the treatment adopted.Case: A 3-year-old male American Pit Bull terrier dog weighing 32 kg was admitted to the hospital with symptoms of acute abdomen, lethargy, increased abdominal volume, discomfort, restlessness, and with a history of collapse three days prior to admission. Clinical examination revealed lethargy, pale mucous membranes, reduced capillary refill time, moderate dehydration, and hyperthermia. Abdominal palpation revealed increased abdominal volume in the epigastric and mesogastric areas. CBC and serum biochemistry profile revealed hypochromic normocytic anemia, leukocytosis with absolute neutrophilia and eosinopenia, mild hypoalbuminemia, and thrombocytopenia. PCR for detection of Babesia sp. and Ehrlichia sp., which returned negative results, and measurement of clotting time, which was prolonged, were performed to exclude immune-mediated hemolytic anemia. Radiographic and ultrasonographic images showed a normal stomach, but revealed presence of splenomegaly. An exploratory laparotomy allowed direct observation of the spleen, which exhibited an increased volume, a blackened, cold, hyperemic appearance, and a complete torsion of the splenic vascular pedicle; the surgical team opted to perform total splenectomy rather than undoing the pedicle twist. The animal returned to the hospital after 10 days exhibiting an excellent clinical condition.[...](AU)

Utilização Da Ultrassonografia Transabdominal Para Auxilio Propedêutico Em Equinos Com Síndrome Cólica: Relato De Casos / Using Transabdominal Ultrasound As Support Diagnosis In Equine With Colic Syndrome: Cases Reports / Uso Del Ultrasonido Transabdominal Como Apoyo Diagnóstico En Equinos Con Síndrome Cólico: Série De 16 Casos

O abdome agudo na espécie equina é considerado uma emergência, sendo de grande importância a determinação precoce da necessidade ou não da intervenção cirúrgica como medida terapêutica. Os objetivos dessa descrição de casos foram: identificar quais os achados ultrassonográficos (US) que auxiliam na determinação do paciente clínico ou cirúrgico, qual a possibilidade de identificação da causa da cólica e expor as dificuldades de execução da técnica. Foi realizado um estudo prospectivo observacional para análise ultrassonografica transabdominal em 16 equinos com sinais de dor abdominal aguda. Um aparelho portátil de alta resolução, acoplado a um transdutor convexo multifrequencial de 2,5 a 5,0 MHz foi utilizado. Como resultados verificou-se que o exame US transabdominal contribuiu para a determinação da conduta a ser adotada em todos os casos. Propiciando o diagnóstico final, detectando achados sugestivos de processo obstrutivo ou descartando-o. Os achados importantes para tomada de decisão e que indicam processo obstrutivo foram: a identificação de anormalidades na topografia intestinal, alterações de motilidade e grau de distenção intestinal, principalmente em intestino delgado, alterações no conteúdo intraluminal e em alguns casos do espessamento de parede intestinal. A atitude do animal em resposta a dor, como agitação/excitação, tremores musculares e eventualmente o tipo de conteúdo intraluminal são alguns fatores que podem prejudicar a análise. Concluiu-se que o exame US transabdominal auxilia na determinação da próxima conduta a ser adotada, cirúrgica ou clínico dos animais com síndrome cólica.(AU)

The acute abdomen in the equine species is considered an emergency. In these cases, it is of great importance the early determination of whether or not a surgical intervention is needed. The aims of this cases descriptions were to identify which sonographic findings help to differ the clinical or surgical patient, to define which lesions can be diagnosed sonographically and to determine the difficulties of the exam. A cross-sectional study was conducted. Sixteen horses with signs of acute abdominal pain were evaluated by means of transabdominal ultrasonography. Ultrasound examination was performed using a portatil high resolution machine with a 2.5 to 5,0MHz, multifrequential convex probe. All abdominal cavity was examined using the starndart ultrasound techinique previous reported. Ultrasound contributed to determine the therapeutic approach in all cases, helping in final diagnosis, and detecting findings of gastrointestinal obstructive process or excluded. The mainly findings in detecting obstructive intestinal process are abnormalities in intestinal topography, pattern of motility and diameter distension, predominantly in small intestine, different intraluminal content and in some cases thickening of intestinal wall. The attitude of the animal in response to pain, agitation/excitement, muscle trembling and sometimes changes in the type of intraluminal content, were factors that interfered in the images. We concluded that transabdominal ultrasonography can assist in determining the next conduct to be adopted, surgical or clinical therapeutics in horses with colic syndrome.(AU)

El abdomen agudo en la especie equina se considera una emergencia y en esos casos es de gran importancia determinar precozmente si una intervención quirúrgica será necesaria o no. Los objetivos al describir esta serie de casos fueron: identificar los hallazgos ultrasonográficos importantes para determinar si los casos eran clínicos o quirúrgicos; verificar la posibilidad de identificar la causa del cólico; y exponer las dificultades al realizar el examen ultrasonográfico en esos casos. De forma prospectiva, fueron incluidos 16 equinos con signos de dolor abdominal agudo. Para el examen ultrasonográfico transabdominal (USTA) fue usado un transductor convexo multifrecuencial de 2,5 a 5,0 MHz acoplado a un ecografo portátil de alta resolución. Fue verificado que el USTA contribuyó para determinar la conducta a ser adoptada en todos los casos; posibilitó llegar a un diagnóstico final; y permitió detectar hallazgos sugestivos de proceso obstructivo e descartar obstrucción. Los hallazgos importantes para tomar decisiones y que indicaron procesos obstructivos fueron: identificación de anormalidades en la topografía intestinal, alteraciones de motilidad y distensión intestinal, principalmente en intestino delgado, alteraciones en el contenido intraluminal y, en algunos casos, espesamiento de la pared intestinal. La actitud del animal en respuesta al dolor, como agitación/excitación, temblores musculares y, eventualmente, el tipo de contenido intraluminal, son algunos factores que pueden perjudicar el examen. Concluimos que el USTA auxilia a determinar si la próxima conducta a ser adoptada en equinos con síndrome cólica será clínica o quirúrgica.(AU)

Timpanismo gastrointestinal em equídeos alimentados com Panicum maximum com alto conteúdo de amido / Intestinal bloat in equids fed with Panicum maximum of high starch content

Timpanismo intestinal agudo em cavalos e mulas introduzidos em pastagens de Panicum maximum cv. Tanzânia, cv. Massai e cv. Mombaça são relatados na região norte do Brasil, durante o período das chuvas. As causas são desconhecidas, porém, tem sido sugerido que estão associados a um maior armazenamento de carboidratos não fibrosos na gramínea. Este trabalho teve por objetivos realizar um levantamento epidemiológico dos surtos de cólicas ocorridos no Estado de Rondônia, assim como contribuir com o estudo da ação dos carboidratos de P. maximum na ocorrência da doença. Para isso foram realizadas visitas em 10 propriedades que apresentaram casos da enfermidade. Em duas propriedades foram introduzidos equinos no mês de março e foram coletadas amostras de pastagens para a determinação de energia digestiva, lisina, matéria seca, carboidratos solúveis em água, carboidratos solúveis em éter, carboidratos não fibrosos, fibra de detergente neutra, fibra de detergente ácido, lignina, amido, gordura e proteína bruta. Essas determinações foram realizadas, também, em amostras de pastagens de P. maximum de outras propriedades onde não estavam ocorrendo cólicas e das pastagens de Cynodon dactylon de onde provinham os equinos. Os resultados mostraram que os surtos de cólica ocorrem na época de chuva, quando as pastagens estão rebrotando com uma morbidade de 31,6%, e letalidade de 86,1%. As análises bromatológicas mostraram uma diferença significativa nas concentrações de amido (P=0,0072) do P. maximum que causou cólica (8,3 % e 9,2%), quando comparado com o P. maximum das outras propriedades (0,9% e 4,3%) e com o Tifton, utilizado previamente na alimentação dos mesmos equinos (0,2% e 0,8%). Em outra fazenda a doença foi reproduzida experimentalmente em um equino, no mês de março administrando P. maximum cortado contendo 6,5% de amido. A mesma pastagem não causou cólica quando foi administrada a equinos entre os meses de novembro a fevereiro, com 2,7% a 5,1% de amido. Estes resultados sugerem que a causa das cólicas em equídeos em pastagens de P. maximum, na época de rebrote, é o alto conteúdo de amido das mesmas.(AU)

Acute intestinal bloat occurs in horses and mules introduced into sprouting Panicum maximum cv. Tanzania, cv. Massai and cv. Mombaça pastures in northern Brazil during the rainy season. It has been suggested that the disease is due to high concentrations of non-structural carbohydrates in this grass. The paper aimed to study outbreaks of colics in the state of Rondônia, Brazil and contribute to the knowledge of the carbohydrates contained in P. maximum as the cause of the disease. For this, ten farms which had cases of intestinal bloat were visited. On two farms, horses were introduced into such a toxic pasture. Samples of pasture were collected for determination of digestible energy, lysine, dry matter, water soluble carbohydrates, ether soluble carbohydrates, non-fiber carbohydrates, neutral detergent fiber, acid detergent fiber, lignin, starch, and fat. Samples of P. maximum pastures from neighboring farms, where the disease was not occurring, and from Cynodon dactylon pastures where the horses had been grazing before were also collected. The results showed that colics occur in the rainy season in sprouting pasture with a morbidity of 31.6%, and lethality of 86.1%. The pastures which induce colic showed significantly (P=0.0072) higher starch concentration (8,3 and 9,2%) than pastures of P. maximum which did not cause colic (0,9 and 4,3%) as well as the Cynodon dactylon pastures ingested previously by the horses (0.2 and 0.8%. On another farm, the disease was produced experimentally in a horse receiving in the feeder P. maximum collected from a toxic pasture with 6.5% of starch. The same pasture did not cause colic from November to February with starch content of 2.7 to 5.1%. It is suggested that the cause of colic in equids ingesting sprouting pasture of P. maximum is the high starch content of this pasture during the groth period.(AU)

Jejunojejunal intussusception in foal: case report / Intussuscepção jejunojejunal em potro: relato de caso

Intussusceptions are unusual intestinal incidents which may result in acute and progressive or recurrent abdominal discomfort in foals. This condition asymptomatically affects newborn foals (3-12 months), are surgical emergencies when it involves the small intestine, especially the jejunum. Transabdominal ultrasound evaluation is an important diagnostic method, due to their size limitations for acute abdomen evaluation. The present report shows the importance of using transabdominal ultrasound in foals with acute abdomen.(AU)

As intussuscepções são acidentes intestinais incomuns e que podem resultar em desconforto abdominal agudo e progressivo ou recorrente em potros. Esta condição afeta potros neonatos de forma assintomática e de 3 a 12 meses são emergências cirúrgicas quando envolvem o intestino delgado, principalmente o jejuno. A avaliação ultrassonográfica transabdominal é um importante para o exame desses animais devido às limitações de seu tamanho para avaliações do abdômen agudo. O presente relato de caso mostra a importância da utilização do ultrassom transabdominal em potros com abdômen agudo.(AU)
