BACKGROUND: The present study aimed to throw light on the clinical characteristics of abomasal impaction in buffalo calves and its associated biochemical alterations. For this reason, a total of 20 male buffalo calves (Bubalus bubalis) with abomasal impaction were studied. The investigated calves were at 6 to 12 months of age and were belonged to three private farms in Dakahlia Governorate besides sporadic cases admitted to the Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Mansoura University, Egypt. Ten apparently healthy buffalo calves were also included as controls. According to the clinical outcome, the diseased calves were categorized into survivors (n = 11) and non-survivors (n = 9). Blood samples were collected from all animals to estimate blood gases besides a panel of selected biochemical parameters. The definitive diagnosis of dietary abomasal impaction was achieved by either left flank exploratory laparotomy or by necropsy. RESULTS: Both survivors and non-survivors demonstrated common clinical findings including distension of ventro-lateral aspect of the right abdomen, and varying degrees of dehydration. The great majority of survivors (81%) and 100% of non-survivors were anorexic and had rumen stasis as well as hard texture upon ballottement of the left flank. Approximately 45% of non-survivors had frothy salivation, expiratory grunting and were being tender when strong percussion was applied on the right flank. Diseased calves had metabolic alkalosis, while plasma potassium and chloride were significantly lower in non-survivors than those of survivors (P < 0.05). Serum malondialdehyde, superoxide dismutase and uric acid were significantly higher in diseased buffalo than controls and in non-survivors than survivors (P < 0.05). Serum total protein, albumin, creatinine, urea, aspartate aminotransferase, gamma-glutamyl transferase, and total bilirubin levels were also higher in non-survivors than those of survivors (P < 0.05). CONCLUSION: Buffalo calves with dietary abomasal impaction were associated with marked clinical and biochemical alterations that could be helpful for an accurate diagnosis of the disease.
