Assessment of the effectiveness of the use of tissue biostimulants in different doses to activate protein metabolism in replacement young cattle
The paper presents studies aimed at studying the effect of the introduction of different doses of a tissue biostimulant on protein metabolism in replacement young cattle. Scientific and economic experience was carried out in 2020 on the basis of JSC “Uchkhoz” Prigorodnoye “Industrial District of Barnaul, Altai region. For the experiment, four groups of heifers of the Ob type of black-and-white breed were formed at the age of one month, similar in live weight (47.5 kg). Animals of the control group were injected subcutaneously with physiological solution at a dose of 3 ml / bird, in the 1st experimental group - a tissue biostimulator at a dose of 2 ml / bird, in the 2nd experimental group - 3 ml / bird, in the 3rd - 4 ml / bird No abscesses were observed at the injection site of the tissue preparation. The tissue biostimulator is made from antler deer slaughter waste in an ultrasound field. It consisted of the placenta, uterus with fetuses, liver, lymph nodes of the mesentery and mediastinum. In the course of the experiment, it was found that the optimal dose of tissue biostimulant application should be considered 3 ml / head, which contributes to an increase in the total protein content in blood serum by 2.1% (P≤0.05), albumin - by 1.0 (P≤ 0.05), β-globulins - by 2.8 (P≤0.05), AST - by 5.8 (P≤0.05)), ALT - by 11.5% (P≤0.05)
