The bioehletic state and hormonal status of the bull-and-haired bull-and-haired breeds of the Yenisei type in the conditions of the Krasnoyarsk Territory (June, 2020)

Purpose: Comprehensive monitoring of bull-and-pystroy bull-producers of the Yenisei type with different blood and hormonal indicators of blood serum on the day of the seed.

Materials and methods. The work was carried out on the manufacturers of the Red-Pesostroy of the Yenisei type in the amount of 12 heads, at the age of 19-31 months. We studied a protein-lipid, mineral metabolism, vitamin-farmenting state and the level of endogenous hormones: testosterone, estradiol, cortisol, thyroxine in blood serum on the day of capture for 20-30 minutes after the sequence is completed.

Results. It was found that protein-lipid metabolism in all bulls, regardless of their bloodiness on average (M+M) is within the normative range. However, there is a 15% bilirubin difference between the groups, the urea is 19% and the PBX by 14%, the difference in cholesterol is 24.6% (p≤0.05). In alkaline phosphatase, the difference between the groups turned out to be reliable at p≤0.05, this contributed to a change in the ratio between CA: P by 36%. There are a reliable difference at the level of p≤0.05 by thyroxine groups. The difference between estradiol groups was 19%, and 9.5%in cortisol. The content of testosterone in both groups was noted at 17.0 mmol/ l. It is proposed to introduce one hundred percent universal and strictly observed system of planned biochemical and hormonal control at least 2 times a year.
