abstract
The present study was carried out to investigate the haemato-biochemical profile of Sirohi goats with the intent of analyzing the physiological alteration under the influence of different lactation stages. Blood samples were collected from twenty clinically healthy female goats at the 1^st, 8^th and 15^th weeks of lactation were compared. The blood was analyzed for hematology and serum for biochemical analysis. The hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), Mean corpuscular hemoglobin concentration (MCHC) were significantly (P<0.01) was the highest at mid and lowest in the early stage of milk production. The neutrophil (%) significantly high level was found at early lactation. However, other leukocytes (%) and total leukocyte count (TLC) have not differed significantly irrespective of milk production stages. The glucose and triglyceride levels were recorded significantly (P<0.05) lowest in the early stage of lactation; whereas, the total protein, albumin and urea (BUN) concentrations were higher in this stage. The serum enzyme variables aspartate aminotranseferase (AST), alanine aminotransferase (ALT) and alkaline phosphates (AP) exhibited a higher significant alteration (P<0.01) in the initial stage. In conclusion, the present study shows marked changes in haematological and biochemical parameters likely to occur due to post-partum are indicative stress.
