Sažetak
The clinical signs of inappetance, poor body condition, pityriasis and decubital skin lesions in 22 stall-fed buffaloes of 18 to 20 months of age warranted the present clinical investigation. The animals were clinically examined and history was collected on feeding and management conditions. The animals had been held on wheat straw based diet supplemented with 0.5 to 0.8 kg concentrate (devoid of vitamin premix) without access to green forage for the last seven months. Six animals had skin sloughing, rough coat, abrasion and two buffaloes were on sternal recumbency and were unable to get up. Blood samples were collected by jugular venepuncture from eight randomly selected from the 22 affected buffaloes, with varying degrees of clinical signs, and from five control buffaloes of a similar age group, who were provided with ad lib green fodder to serve as control. Serum samples were analyzed for blood glucose, total protein, albumin, urea, uric acid, creatinine, calcium, and phosphorous. Aspartate animo-transferase (AST) and alanine amino-transferase (ALT) activities were significantly (P<0.01) lower in serum from affected animals, indicating reduced hepatic function. Alkaline phosphatase activities (AP), along with serum cholesterol level were also significantly (P<0.05) lower in zero-green fed animals compared to the controls. Blood copper and zinc concentrations were statistically comparable in both the groups, but the mean values for cobalt and iron were significantly lower in affected animals. Mean plasma level of vitamin A, ß-carotene and α-tocopherol was significantly (P<0.01) lower in affected animals than in the controls. This is the first report documenting the combined deficiency of vitamin A and its precursor ß- carotene along with α-tocopherol, and the affected animals had reduced hepatic function. The present investigation strongly suggests provision of green fodder or supplementation of vitamins in the diet of buffaloes to avoid poor health and clinical signs associated with deficiency.
