Alimentary using of «Humapol» as a method of sperm quality correction in rams

In Russian industrial system, sheep breeding is an important branch of productive livestock husbandry, which supplies the industry with valuable raw materials. The increase in sheep production is possible not only due to the increase in the productivity of animals. The results of scientific research and practice show that in improving the breeding and productive qualities of animals an important role should be assigned to the sires. Sheep are fertile animals, a relatively short period of their pregnancy provides them with high reproductive capacity. Despite the fact that their reproductive qualities are good, nevertheless, the issues of improving the quality of sperm production of sires remain relevant. This article presents the results of studies aimed at correcting the quality of sperm production obtained from sheep of Romanov breed and ram of catadin breed by feeding an additive based on humic acids “Humapol”. In the ration feed powder additive based on humic acids "Humapol" were added. The additive was fed at a dose of 10 g / head three times a week for one month. The ejaculates, obtained using an artificial vagina, were examined twice a week for two months using standard methods for assessing the quality of sperm. The study assessed: density and activity using the crushed drop method, concentration using the chamber method using the Gorjaev's count chamber, intensity of the redox sperm processes using the Shergin’s method with methylene blue, the percentage of alive spermatozoa was determined using the Morozov’s method using eosin solution. According to the research, there was a persistent increase in sperm concentration. There was also an increase in activity, an increase in the level of respiration. The results indicate a positive correction of semen quality.
