The influence of linear fashion accessories bulls and cows mothers content on exterior and interior features of heifers of the Ural black pied type from birth to 9 months

 The influence on the growth and development of repair heifers of two factors: the line of bull (Vis and Reflection
Sovering IDEA) and the method of keeping cows mothers. In the development of dairy farming such example is the introduction
of loose housing of cows, the development of the cold method of rearing. Loose housing of cows compared with fastened
content can significantly reduce labor costs, more efficient use of mechanization of production processes, the use of milking
machines type of machine improves the working conditions in the milking process, making it an attractive and productive, lets
you control the state of each cow, to optimize her diet, to manage the process of milking, track quality parameters of milk. Each
cow chooses an optimal regime between milkings. In the Sverdlovsk region in the farms with loose housing increase milk production
from 2006 to 2011, was 2 times higher than in farms with cows tethered content. The most commonly accepted loose
housing with garages to stay isolated from the feeding area dung passage. Isolation wards allow to save a covering material.
Of the four groups of heifers line Reflection Sovering whose mothers contained manner to 9 months developing more rapidly
than their counterparts in the other groups. In the same line of heifers whose mothers were kept on a leash situation is completely
different. Between the growth and development of heifers line Vis IDEA whose mothers were kept as loose- and tethered
method tangible differences were observed. Heifers line Vis IDEA also differ best hematological parameters compared to their
counterparts Reflection Sovering line.
