Biotechnological methods in increasing the fertility of sheep of the soviet merino breed

Abstract

In animal husbandry practice, hormonal substances are increasingly used to regulate the reproduction processes of farm animals. Reproduction biotechnology includes all activities carried out for the purpose of a systematic and controlled process of reproduction of economically useful animals. Such measures include, for example, the whole range of measures for artificial insemination, special hormonal treatment regimes, or a special change of light and darkness, which makes it possible to induce heat cycles in sheep even during the anestrous period. Directed regulation of the reproductive functions of animals is based on the ability of sex and gonadotropic hormones to cause early puberty, superovulation, stimulation and inhibition of estrus.
