PROMISING BIOTECHNOLOGY OF SHEEP AND GOATS REPRODUCTION

Aybazov А.-M.M., GNU SNIIZHK et al. [201407/2014]

Currently, artificial insemination of sheep and goats is based on spontaneous estrus. As a rule, this technology is very time-consuming and energy-intensive and extends 1.5 - 2.0 months. One of the ways to intensify the process of reproduction is a biotechnological method of synchronization of the sexual cycle. The use of estrus synchronization technology will allow to change fundamentally the ...

CONSTITUTION FEATURES OF KARACHAI BREED SHEEP IN DIFFERENT GENOTYPES

Gadzhiev Z. K., GNU SNIIZHK et al. [201407/2014]

The article presents results of constitution measurements of each interbreed type. The comparative characteristic of constitution indexes on groups is carried out. The analysis of constitution measurements shows a superiority of animals like "kara-myuyuz" and "tumak" that indicates a good development of body weight of these sheep getting expressed meat forms. Good development of a constitution ...

MEAT FINE-WOOL BREED ETTI MERINO, BRED IN KAZAKHSTAN

Kasenov T.K., Kazakh NII of Sheep Breeding et al. [201407/2014]

Of all produced meat and meat products mutton production, one of the traditional foods of the Kazakh people, takes 15-20%. To meet the needs in the demand for mutton it is necessary to create new regionalized specialized meat, meat-wool breeds by "foreign type" and partial absorption of local breeds. In the article are given the history and the prerequisites of the creation in Kazakhstan of ne ...

One of the ways of rational management of animal breeding is the active involvement in agricultural production resources of wild fauna, including using of hybridization. West Caucasian wild goat, despite some exterior features, is phylogenetically closely related to domestic goats and should be considered as a kind of geographical ancestors of domestic goat. The article shows that the hybridiz ...
