Bolotov Y. Improvement of technological receptions of increase of sperm productivity of rams and reproductive qualities of ewes different directions of productivity

The object of researches is Forming of reproductive qualities of sheep of a different direction of productivity depending on inherited, paratipik factors and technological receptions. The purpose of researches is the improvement of the system of the rational use of pedigree rams-producers and ewes on the basis of development of technological receptions of kriokonservatsii sperm of animal different genotypes and application of biologicheski-aktivnih matters in their feeding. The methods of researches are zootechnicss, biological, laboratory, biometricheskie, analytical. Results of researches: 1. For a theory - influence is First set on the spermoproduktivnost rams-producers of tavria type of askaniyskoy to fine-fleece and askaniyskoy karakul breeds of the use of biologicheski-aktivnih matters. First it is proved on the sheep of askaniyskoy fine-fleece breed, that kriokonservatsiya and the subsequent saving of sperm in payetah takes substantial advantage above the method of freezing and saving of sperm in the opened granules. 2. For practice - Inclusion to the ration of rams-producers of vitamin-mineral addition of marine origin in a quantity 15% after mass, in place of corn of barley and wheat, is instrumental in the increase of volume of eyakulyata on 19-22% and quantities of spermiev in eyakulyate on 33-36%. The use of the developed syringe-catheter, at double insemination of ewes in one hunt with an interval 10-12 hours, provides the rise of oplodotvorimosti on 12,5% and receipt additionally of 18,3% lambs on 100 inseminated ewes. Sphere of the use - sheep-breeding economies.
