Abstract
In recent years, goat breeds with a dairy-meat-wool or combined productivity type, represented by local breeds that are bred mainly in the foothills and mountainous regions of the North Caucasus, Altai, Tyva and Khakassia, have become increasingly widespread in Russia. The Karachay goat population is the most interesting for research, since in their breeding was aimed at obtaining animals with a number of unique productive characteristics and capable of producing the required outputs under the harsh conditions of the mountain and foothill zones of the Caucasus. In view of the limited research on these animals, in particular their reproductive functions, the aim of this study was to investigate the natural implementation of the reproductive function of the Karachay goats in different geographical areas of breeding. There are slight differences in some parameters of Karachay goat reproduction in high mountain zone (from 2000 m a.s.l.) and middle mountain zone (1000–1500 m a.s.l.). An important conclusion is that the recognized low fertility of the Karachay goats is not genetically determined. Analyzing the number of ovulations and fresh yellow bodies in the ovaries by laparoscopy using Karl Storz (Germany) endoscopic equipment, the authors found a potential fecundity of 3.1 (2.8 to 3.4).
