This study aimed to evaluate the systemic implications of 37 cattle with traumatic reticulitis, evaluating clinical, laboratory, ultrasonographic and necroscopic changes. A clinical, laboratory and ultrasonographic examination was performed, and the animals were distributed in reticuloperitonitis (GI; n=21) and reticulopericarditis (GII; n=16) traumatic, based on necropsy findings. Blood samples were taken for haematological tests, serum total protein, albumin, globulin, gamma glutamyltransferase (GGT), aspartate aminotransferase (AST), glutamate dehydrogenase (GLDH), creatinine, urea, cortisol, creatine kinase (CK), creatine kinase-MB (CK-MB), cardiac troponin-I (cTn-I), plasma glucose and L-lactate. The abdominocentesis was productive in eight GI (n=8) and seven GII (n=7) animals, allowing the evaluation of physical, cytological and biochemical characteristics of the peritoneal fluid as a total protein, albumin, GLDH, AST, GGT, glucose and L-lactate. Changes in behavior, appetite, dehydration and temperature were observed, most expressive in GII. Hematology showed neutrophilic leukocytosis with regenerative left shift and hyperfibrinogenemia in both groups. Increased globulin, L-lactate concentration and serum GGT, GLDH, CK and CK-MB activity were observed, as well as significant elevation of cTnI (p=0.0190) in GII. In the peritoneal fluid exudate was observed in both groups and a higher concentration of L-lactate in relation to plasma. Ultrasound revealed retocular, cardiac, hepatic and splenic abnormalities. The anatomopathological lesions confirmed the ultrasound findings of both groups. The understanding of the syndrome helps in the diagnosis, as well as the adoption of preventive measures, minimizing the economic impact caused to the dairy cattle breeding.

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.
