Main ingredients of success of AO Zarya, the breeding plant in Tula region

AO Zarya, the breeding plant, is a leading agricultural enterprise in Tula region for Ayrshire cattle breeding. Constant growth of milk yield, both in particular age groups of cows and within the herd as a whole, is achieved through the cow culling system and the introduction of a large number of heifers into the herd (from 44.2 % in 2014 to 30.0 % in 2016). According to the valuation over a period of 2013 - 2016, 32,7; 2,3; 18.6 and 23,0% per each year accordingly, were ranked with respect to low productivity. To ensure a significant introduction of heifers into the herd, it is necessary to produce a large number of calves which must be kept safe during ontogenesis. The farm applies a so-called cold method for calf growing. The gist of it is that almost from the moment of birth, or rather, three hours after the birth in the individual cage on the farm, a calf is placed in the environment as close to natural, that is an outdoor plastic house, regardless of the season of the year. Cold method of calf growing has its undeniable advantages. They are high survival rate of young cattle, up to 100 %, its high-level immunity, as well as further easy maintenance of adult stock. The calf growing method adopted by AO Zarya supports a uniform distribution according to the superiority over peers as to live weight of heifers aged 10 and 12 months old (Breeding Value of live weight aged 10 months old, Breeding Value of live weight aged 12 month old). So, 54.8 % of animals in the first group, and 52.9 % in the second, fall behind in weight gain as compared to peers, in a range of -0.1 to -60,0 kg. The curves of absolute milk yield and breeding value for milk yield indicate that 10-month-old heifers with a higher live weight gain have the advantage for milk yield against their peers. For example, 12 cows which lack more than 60 kg in weight gave 5895 kg of milk, and those which outweigh 60 kg or more (n = 16) gave 6312 kg, that is 417 kg more. Compared to peers, the difference was -10 and +140 kg of milk. On average, the offspring of bulls from OAO PP Cherepovetskoye show the best developmental indicators. In addition, the children of such bulls as Volan 505 (OAO GCV), Ivanhoe 491 (OAO Nevskoye), 10653489, Solero, 10707843 Eugene, 107344428 Chakid, 2184 Oligarch, 268 Visit and 556 Marmelad (OAO PP Cherepovetskoye") may be noted individually.
