Neonatal calf mortality in Pakistan . II : haematological indices in healthy and diseased buffalo and cow neonates.

摘要

Haematological studies carried on apparently healthy buffalo and cow newborn calves showed insignificant differences for sex of the valves and parity of the dams. The number of RBCs was significantly less whereas Hb. concentration, packed cell volume (PCV), mean corpuscular volume, mean corpuscular haemoglobin concentration (MCHC) and total leukocyte count were significantly higher at birth in healthy calves. Significantly low ESR was significantly low at birth in buffaloes but cow calves showed insignificant variations. Rouleaux formation was observed in buffalo calves. Neutrophils showed significantly higher counts at birth than lymphocytes and from the second week, lymphocyte counts higher number than neutrophils and this trend continued up tofourth week of age. In buffalo and cow calves with diarrhoea and pneumo-enteritis RBC and PCV were significantly increased whereas MCHC were significantly decreased. Leukocytosis mainly due to neutrophilia along with lymphocytopenia was associated with diarrhoea, pneumonia and pneumo-enteritis in calves.
