Deslocamento do abomaso é uma paratopia que ocorre com menor frequência em bezerros, touros e novilhas, quando comparado com vacas de alta produção leiteira. Objetivou-se relatar o caso de um bezerro, macho, com três meses de idade, atendido na rotina hospitalar da Clínica de Bovinos de Garanhuns. Segundo anamnese, o animal alimentava-se de leite, pasto nativo, grama, xerém de milho e farelo de trigo (200g/dia). Entretanto três dias antes da baixa, foi alimentado com palha de milho, apresentando em seguida timpania ruminal, dificuldade de locomoção e aumento do consumo de água. As fezes estavam escassas, liquefeitas e amareladas. Caso único, num total de 30 animais. Os principais sinais clínicos observados foram apatia, mucosas congestas, exsicose grau III, moderada enoftalmia, abdômen tenso, com formato maçã-pera, à percussão auscultatória evidenciou-se um som de “ping” metálico, na região do 12º espaço intercostal do flanco direito. As análises laboratoriais revelaram teor de cloretos elevado, de 81,88 mEq/L; hemoconcentração, leucocitose, por linfocitose e neutrofilia, com desvio à esquerda regenerativo, além de hipoproteinemia. Em função do diagnóstico de deslocamento de abomaso à direita (DAD), foi submetido à laparotomia exploratória pelo flanco direito. Nesta condição, o órgão estava bastante distendido por gás e conteúdo líquido. Seguindo o protocolo terapêutico, o animal apresentou evolução clínica satisfatória, recebendo alta no quinto dia após seu internamento. Conclui-se que deslocamento de abomaso à direita é uma afecção grave e, apesar da baixa frequência em bezerros, pode acometer essa faixa etária, acarretando prejuízos ao produtor, e o que reitera a necessidade de prevenir os fatores de risco associados a essa síndrome multifatorial.

This study aimed to evaluate laparoscopy with abdominal ultrasound exams to establish accurate diagnosis and prognosis. The experimental design was a prospective clinical study. Nine adult crossbred bovines suffering from abdominal disorders were admitted to the cattle clinic for clinical examinations. Abdominal ultrasound was carried out, and complete blood counts were performed. Subsequently, exploratory laparoscopy was performed. After surgery (exploratory laparoscopy on the right or left side), animals with a severe prognosis or untreatable clinical condition were euthanised and necropsied. During laparoscopy, circumscribed reticuloperitonitis could not be detected, nor could other abnormalities in the cranioventral region of the abdomen previously observed on ultrasound and confirmed during necropsy. However, alterations due to peritoneal damage, such as adhesions, were observed dorsally in addition to alterations in macroscopic aspects of the peritoneal fluid. Exploratory standing laparoscopy through the paralumbar fossae may constitute a supplementary procedure for diagnosing abdominal disorders in cattle, but it is not suitable in cases of diseases characterised by focal lesions concentrated in the cranioventral region of the abdomen. When associated with clinical, laboratory, and ultrasound examinations, this technique may improve the accurate diagnosis and prognosis of abdominal disorders in cattle.

This study proposed to characterize the effects of feeding based on whole corn grain diet on the dynamics of clinical parameters and biochemical metabolites of confined cattle. Twenty adult mixed-breed cattle, with an average weight of 300 kg, were used, divided into two experimental groups. The experimental group (G1; n=15), composed of animals fed only Max Beef Grain Whole diet and the control group (G2; n=5), composed of animals, fed with sugarcane bagasse and the Max Beef Grain Whole grain diet, in the 30:70 ratio. All animals were submitted to clinical observations, blood collection by jugular venipuncture and ruminal fluid. The animals that received Max Beef Grain Whole Diet were clinically demonstrated with incomplete ruminal movements, mild ruminal tympania and diarrhea with whole corn grains. He did not show changes in hematology or in the concentration of fibrinogen. They presented a lower ruminal pH value during the whole experimental period, with impaired rumen fluid population, reduction of the methylene blue reduction test and absence of sedimentation and absent flotation. It was concluded that the inclusion of diets containing Max Beef Whole Grain for confined cattle causes chronic ruminal acidosis and compromises the physical-chemical and microbiological characteristics of the ruminal fluid.

This work aims to describe the clinical, laboratory, and anatomopathological findings of two bovines, one affected by cecocolic intussusception, and the other by dilation with cecal torsion. The clinical examination demonstrated metallic resonance from the right flank, ruminal and intestinal hypomotility, and abdominal distension, in addition to alterations in feces characteristics. Was observed in the two animals leukocytosis by neutrophilia with regenerative shift to the left, and hyperfibrinogenemia. The analysis of ruminal fluid revealed impairment of the microbiota and an increase in chloride levels. The laparoscopic examination performed on one of the animals showed dilation of the colon, the cecum with hyperemia and serous edema, with a dividing halo between affected and unaffected portions, in addition to reddish peritoneal fluid. In the laparotomy, an enlarged cecum was found, with gaseous and liquid contents, swollen and turgid colon, and peritonitis. In addition to the findings observed during surgery, the anatomopathological examination demonstrated, in bovine 01, intestinal intussusception in the region of the cecocolic valve, and, in bovine 02, twisting of the loop at the ileocecocolic junction. Despite the low occurrence of digestive system disorders in cattle, cecal torsion and intussusception represent serious intestinal clinical conditions. These reports take the attention to the importance of a multidisciplinary approach to provide a correct diagnosis of intestinal diseases.
