HAEMATO-BIOCHEMICAL ANALYSIS OF CATTLE IN A COMMERCIAL DAIRY FARM

Abstract

Haematological parameters are changed in different species of animals due to physiological alteration and pathological causes.The aim of the present study was to investigate and compare the blood composition of cows and their milk feeding calves. Blood sample were collected from 30 cross breed clinically healthy calves (16 male and 14 female) and 30 cross breed clinically healthy cows. Total erythrocyte count(TEC), Differential Leukocyte count (DLC), average mean values of hemoglobin (Hb), Packed cell volume(PCV), Mean corpuscular volume(MCV), Mean corpuscular hemoglobin (MCH), Mean corpuscular hemoglobin concentration (MCHC) were determined by using routine hematological procedures and calcium, phosphorus, glucose, total protein, albumin, globulin, albumin-globulin ratio & cholesterol were determined by using biochemical analyzer. There were significant variations found in most hematological and biochemical parameters (p < 0.05) but all the values are within the reference range. The results of the study showed that among hematological parameters Hb concentration (8.28 ± 0.846 gm/dl), total RBC count (6.37 ± 0.66 ×106/μl), lymphocyte (64.26 ± 5.91%), monocyte (9.26 ± 3.39 %) was significantly higher in calves than cows. On the other hand neutrophil (21.10 ± 5.29%), eosinophil (10.07 ± 3.75%) and MCV (49.99 ± 5.16 ft) was significantly higher in cows than calves. Comparing with the biochemical parameters between cow and calf, glucose level (57.68 ± 2.67 mg/dl) was significantly higher in milk feeding calves but total protein level (7.70 ± 1.17gm/dl), globulin (4.00 ± 0.53),cholesterol (21.20 ±3.50) were significantly higher in cows. It may be concluded that hemato-biochemical variation present between cows & calves and it is very important for interpretation of laboratory data.
