Influence of cutting antlers on the biochemical composition of blood of male reindeer

Abstract

The results of the research experiment on resection of growing antlers in males in the herd of domestic reindeer on Yamal are presented. In June, two groups of animals similar in age were formed: the experimental group with cut and the control group with preserved antlers. The comparison between the groups was carried out on the basis of eye assessment of deer and biochemical blood parameters. Blood was taken for the study in July and October. It showed that the resection of antlers affected the total protein content of the blood serum of deer in the direction of increasing its concentration. By the ratio of protein fractions between groups, the picture is more diverse. Thus, in the experimental group the albumin content was higher-by 2.44 g / l, but lower - globulins, while the difference in α1 - fraction was statistically significant (p≤0.01). For α2 - and β-globulins the difference is insignificant, for γ-globulins no difference was found. The experimental group of deer exceeded the control group by almost 24% in the content of amylase., but the difference has not reached the minimum level of confidence. The superiority of the control group in the content of cholesterol (P ≤ 0.01), which is known to serve as a material for the formation of sex hormones-androgens, was reliable. The biochemical picture of deer blood in autumn, before the chase, showed a significant advantage of the animals of the experimental group on the content of total protein at a reliable level (p ≤ 0.05), but due to the superiority in the content of globulin fractions. The relative albumin content in the blood serum of deer in October is higher than in July, the amylase content in the serum of animals in the control group fell by almost two, the experimental - three and a half times. The content of calcium and phosphorus in the blood of animals of both groups during the study period was almost the same. At the same time in the body of males in October decreases cholesterol, but the difference between the groups is negligible. Lowering cholesterol in the blood of males after resection of the antlers can slow the formation of sex hormones-androgens.
