Biochemical and hormonal characteristics of peripheral blood in bulls in relation to genotype.

Abstract

The study aimed at investigating differences in selected peripheral blood biochemical parameters and hormones in bulls of various genotype: Polish Holstein-Friesians (PHF; group I) and crossbreeds obtained from PHF dams sired by Limousin bulls (LMxPHF; group II). The blood for analysis was taken from the jugular vein twice. In blood serum the content of glucose, total protein, albumin, urea, total cholesterol, HDL, triglyceride , AST and ALT activity were determined. Insulin, triiodothyronine (T₃) and thyroxine (T₄) concentrations were also evaluated. The results showed that the insulin concentration and aspartate aminotransferase activity (AST) was significantly different (P No References for this article. No Supplementary Data.
