Teneva, A., Hristov, K. & Stoimenov, G. (2020). Blood biochemical profiles of dairy cows and their calves from Bulgarian Black and White Cattle Breed. Bulg. J. Agric. Sci., 26 (4), 890–893
This study examined the activities of aspartate aminotransferase (ASAT), alanine aminotrans-ferase (ALAT), alkaline phosphatase (ALP), acid phosphatase (ACP), albumin (Alb), total protein (TP), creatin-phosphokinase (CPK), total lipid (TL), calcium (Ca) in the plasma of 304 dairy Holstein breed cows and their calves. 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 significant difference (P < 0.05) in mean of the ASAT, ALAT, ALP, ACP, Alb, TP, TL, Ca between cows and calves of the breed. Mean values of the ASAT, ALAT, Alb, TP, TL and Ca was higher in cow group than in calves group (P < 0.05), while ALP and ACP was lower in cow in comparison to the calves group (P < 0.05).
