APPLICATION OF LIQUID WATER-SOLUBLE FEED ADDITIVE "REASIL HUMIC VET" TO INCREASE THE REPRODUCTIVE CAPACITY OF COCKS

The materials presented in the article describe the solution to the problem of early culling of brood males, preserving their reproductive health, reproductive ability and the quality of the resulting sperm products through the use of a liquid water-soluble feed additive of complex action "Reasil Humic Vet", consisting of a concentrated solution of high molecular weight sodium salts of humic acids from leonardite. An assessment of the reaction of male-breeders of meat cross to the transfer from floor to cage keeping was carried out. The experiments were carried out in the veterinary clinic of the Faculty of Veterinary Medicine, Food and Biotechnology of the Federal State Budgetary Educational Institution of Higher Education of the Saratov State Agrarian University in the period 2020-2021. In the experiment, roosters of the POCC 308 breed were used. Drinking with water a liquid water-soluble feed additive of complex action "Reasil Humic Vet" neutralizes the negative stress effect on the organism of the males. The variability and level of biochemical parameters of blood plasma in males of the 1st control group were significantly higher for the content of triglycerides and cholesterol, which characterize fat metabolism. The criterion for selecting males for the experiment was the primary reaction to massage by the method of Burrows W. A., Quinn J. P. To assess the volume of ejaculates obtained and determine the indicator of sperm activity, the selected livestock was divided into two groups: group 1 (n = 5) - control; Group 2 (n = 5), the subject received "Reasil Humic Vet" with water. The studied livestock had an ejaculate volume of 0.1 ml to 1.1 ml. The indicator of sperm activity in the 1st group at the first assessment ranged from 5.9 to 8.7 points. The increase in sperm activity in the second group occurred on day 20 and the next day of the experiment after transfer to individual cells and showed a stable result from 8.5 to 9.5 points. As a result of the experiment on the study of the quality indicators of sperm in the 2nd experimental group of males, high indicators of Cv variability were obtained from 32.0% to 54.0%.
