Sažetak
In the present research the influence of metabolic parameters on return of ovarian cyclicity in puerperium of Holstein-frisian cows was investigated. We determined following metabolic parameters: glucose, total proteins, urea, enzymes AST, ALT and enzyme creatine kinase in total of 30 cows, during the 45 days of puerperium. Cows between 2 and 4 years old were examined gynecological and with ultrasound. Cows were divided in two groups based on their lactation. In the first group, lactation was <30 L daily, and in the second group >30 L. Blood samples were taken from v. coccigea twice a week starting from day 4 till day 45 of puerperium. Samples were centrifuged and stored frozen on -20°C till further biochemical tests. We determined significant difference (P<0, 05) for enzymes AST and ALT between both groups of cows. The results of our research showed that the group of cows with the milk production >30 L had significantly increased AST and ALT levels, in relation to the group of cows with milk production <30 L, and also considering pshysiologic levels. However, creatine kinase levels were in physiologic levels in both groups of cows, and did not significantly differ between mentioned groups of cows. The obtained results suggest that the group of cows with higher milk production had liver damages, and that could be connected to the later return of ovarian cyclicity. Based on that, we can conclude that in the cows with higher milk production hypothalamus-pituitary-ovarian axis would not be reestablished in the physiological time postpartum.
