The main factor in creating highly productive herds, both in order and importance, is the intensive cultivation of repair heifers. Only well-developed and constitutionally strong animals are capable of high productivity without compromising their health. The live weight of an adult cow and the proportionality of its physique are laid from an early age. The underdevelopment allowed during cultivation is not fully compensated even after the improvement of feeding and keeping conditions. Therefore, it is not uncommon for our farms to find smallness of adult animals, deficiencies in the exterior, weak bones and ligaments, and hence difficult calving with complications, infertility and barrenness, and premature retirement of the most genetically valuable cows, and, as a result, the unrealized benefit from their use.

It is impossible to save money on rearing young animals, on the contrary, this is the most profitable investment of capital. Additional costs to improve their feeding and maintenance are repeatedly blocked due to calving at an earlier age and increasing the productivity of cows in the future. Therefore, the cultivation of heifers for herd repair should be only intensive. The average daily gain should be at least 700 g, the age at the first insemination – within 17-18 months, while the live weight should be 380-420 kg.

The most important condition for increasing the herd’s productivity is repairing it with heifers, primarily those originating from highly productive mothers – cows from the breeding core, as well as those selected according to their own productivity, because between milk yield for I lactation and subsequent there is a positive relationship. Repair of the herd with proven first-calf heifers allows increasing milk production on the farm by 10-12%. All these are known factors, which, unfortunately, are neglected in practice.

The effect of introducing a large number of heifers into the herd is achieved when their milk yield is 80-90% of the average indicator for the herd. In particular for st …
