Резюме: The aim of the present study was to estimate the values of some biochemical parameters - ALT, AST, ALP, Fe and glucose of two Karakachan sheep herds – IAS-Kostinbrod (I.) and Milanovo (M.), reared at different altitudes (740 and 1150 m above sea level, resp.) with different body condition score (BCS) and hematocrit (HCT) levels. Analysis of biochemical parameters was performed in extracted plasma with a BTS-350 Semi Automated Biochemical Analyser. The body condition score was performed during sampling.
The BCS of the sheep from the herd of I. was better than that of the animals from M., as the difference was significant for the herds overall (p<0.05). The HCT levels of the sheep from the I. herd were also higher (but not significantly) than those of the animals from M. The activity of ALT was higher than reference values and significantly lower in the sheep from M. compared to those from I. in general for the herds (p<0.001) and in the group with low HCT (p<0.01). The activities of AST and ALP were lower than reference values, as well as the levels of plasma iron and glucose. The differences were significantly higher in the sheep from M. compared to those from I. in general for the herds (AST, ALP, Fe and glucose - p<0.001) and in the group with low HCT (ALP - p<0.05, AST and Fe - p<0.01 and AST - p<0.001). In the group with a high HCT, there were no significant differences in all biochemical parameters.
