ANALYSIS OF BLOOD BIOCHEMICAL PROFILES OF DAIRY COWS AND THEIR CALVES FROM BULGARIAN BROWN CATTLE BREED

Abstract

Present study was conducted to analyze the blood biochemical parameters of a total 271 Bulgarian Brown Cattle Breed and their calves. We evaluated the activities of aspartate aminotransferase (ASAT), alanine ami-notrans-ferase (ALAT), alkaline phosphatase (ALP), acid phosphatase (ACP), albumin (Alb), total protein (TP), creatin-phosphokinase (CPK), total lipid (TL), calcium (Ca), ceruloplasmin (CP) in their serum. The cows was 2–12 years old, mean body weight 600 kg and the calves 1–9 months old. The cows were held in an intensive farm breeding premises. Their meal consisted of ordinary alfalfa, silage, hay and concentrates with energy and protein supplements. The Student t-test showed a significant difference (P < 0.05) in mean of the ASAT, ALAT, ALP, ACP, Alb, TP, TL, Ca, Cp between cows and calves of the breed. Mean values of the Alb, TP, CPK, Cp and Ca was higher in cow group than in calves group (P < 0.05), while ASAT, ALAT, ALP, ACP, TL was lower in cow in comparison to the calves group (P < 0.05).
