Sažetak
The aim of our research was to establish the influence of metabolic parameters on return of ovarian cyclicity in puerperium of simmental cows. We determined following metabolic parameters: glucose, total proteins, urea, isoenzymes AST, ALT and enzyme creatine kinase in 20 cows in total, during the 45 days of puerperium. Cows who were 2-10 years old, were examined gynecological and by ultrasound. We divided cows in two groups on basis of their lactation. In first group lactation consisted <25 L daily, and in second group > 25 L. We took blood samples from V. coccigea twice weekly starting from day 4. till 45. of puerperium. Samples were centrifuged and stored frozen on -20°C till biochemical tests. We determined significant difference (P<0, 00001) for urea and isoenzymes AST and ALT between both groups of cows. But, we did not determine significant difference (P>0, 05) for glucose, total proteins and CK. The comparison of correlation between metabolic parameters has shown strong, positive and significant correlations only between AST and CK (r=0, 51 ; P<0, 05). As already known, AST activity increases in serum by muscle and liver diseases. So it is necessary for distinguishing liver diseases from skeletal injuries on basis of laboratory test to determine level of creatine kinase in sera. Our tests have shown that group of cows with higher milk production in our study had no liver diseases although they had increased level of izoenzyme AST (P<0.00001). We can conclude that hypothalamus-pituitary-ovarian axis would be reestablished in physiological time postpartum.
