The results of the selection it is necessary to carry out the annual entry in the main herd heifers not less than 25-30 heads per 100 cows.

19. To obtain repair breeding bulls and embryos from specialized meat breeds are used in high-value animals. The potential productivity of mothers of bulls and repair of donor-cows of meat breeds should be 1000-1200 grams per day. Breeding (genetic) value of bulls-manufacturers have to surpass the average Republican population indicators breed characteristics (productivity, vitality, reproductive and other signs).

28. Term use of mares in breeding farms and custom (commercial) herds an average of 16 years, stallions 20 years.

29. Given the long period of use, to prevent sibling mating required to maintain constant exchange of breeding sires on the basis of regional rotation plan within the district, region, and high-value stallions in the country and other countries.

30. Plans rotation stallions, organization and monitoring of the exchange at the regional level is provided by the state breeding service, respectively, district, region and Republic.

31. Uses a three-level organization of breeding work:

  • first level - work in the breeding stud, is aimed at selection of potential mothers of stallions. Is grown high quality replacement stock, especially stallions for reproduction of the breed, picking a pedigree breeding and export sales. Reproduction of horses is carried out using artificial insemination with semen of high valuable stallions new generations;

  • level three - work in a custom (commercial) herds with a small number of breeding horse population. Breeding ewes should be concentrated on private farms, where they are fixed and selected by the rotation system stallions-manufacturers. The young are grown and used in accordance with industry regulations. Reproduction of livestock is carried out using manual or markovoy mating mares.

32. Selection of rearing for use in the reproduction of livestock is carried out at all stages of its cultivation, initially at the origin, typicality, measurements, exterior, in subsequent years further assessed by performance (if needed for milk and meat production), reproductive ability, in accordance with the adopted in the breeding farm or custom (product) stud technology.

breeding stock

36. Used pedigree products (material) in sheep breeding, goat breeding, fur farming, rabbit breeding, beekeeping and fish farming must be purebred, confirmed by birth in the relation to ancestors four generations and have a pedigree (genetic) value.

The primary method of reproduction of fish is the use of breeding males. In fish farming the primary method of reproduction of pure-bred species of carp, salmon, sturgeon and other species is artificial insemination, in carp farming allowed natural spawning.

37. Pedigree products (material) with indicators of breeding values below the average population indices of the breed, is rejected.

38. Pedigree products (material), used for breeding in the breeding sector and in its implementation in a custom (commercial) herds for further reproduction of livestock, should have indicators of an estimation of breeding value:

  • goat farming - reproduction and milk production;
  • fur farming and rabbit breeding by color, quality, pubescence, length of hair, live weight, reproductive abilities;
  • in beekeeping - fertility of ewes, honney- Vasoprotectives, winter hardiness and resistance to stress factors;
  • farming - at resilience, weight, condition, conformation, and genetic indicators.
