Comparative characteristics of goats semen for service depending on sperm production method

Goat breeding as a livestock sector plays a big role in the production of milk and meat in many countries. For a long period in our country, espe- cially in public sector, there has been a downward trend in the number of goats. However, restoration and development of the branch should take place not only by increasing the number of livestock and by improving productive qualities. The use of as-sisted reproductive technology may play a role in solving this problem. In this regard, the research aimed at studying biological full-value of goat se-men for service is relevant. The study was carried out in the laboratory of reproductive cryobiology of the Federal Research Center of animal husbandry - L.K. Ernst Institute of animal husbandry. Biore-source collection "Cryobank" was used during the study. Ejaculated semen was prepared by two methods: the method in goat's artificial vagina in estrus and the method of electric ejaculation from goats for service of the Saanen (n = 8) and F1 hy-brids (n = 2) (Siberian ibex x Saanen). The epidid-ymal semen was obtained by the fistula method from Saanen sire (n = 3) and postmortem (n = 2).The content of spermatozoa with rectilinear translational motion was 95.4 % in the samples obtained via artificial vagina. It was 5 % more than using electrical stimulation and 6.8 % when using fistula. The activity of the spermatozoa obtained by the method of electrical stimulation decreased as a result of samples cryopreservation. The number of spermatozoa with rectilinear translational motion was only 37 %. The content of spermatozoa with intact acrosome in the samples obtained from epi-didymis decreased by 27 %.
