Growth and meat qualities of young Black-and-White breed in different age periods depending on the feeding level

By regulating the nutritional level of young animals in postembryonic period, it is possible to change growth rate animals, forming meatiness and ratio most important tissues carcass. The aim work was establish influence different levels on growth, development, meat productivity Black Pied cattle ages. scheme growing as follows: group 1– increased up 14 months age; 1-a – were grown same way 1 8 (increased level), from they average nutrition; 2 nutrition months; 2-a months, an level. During growing, spent each head 2114.8; 1888.1; 1919.0; 1692.3 energetic feed units. 18 respectively: 3673.2; 3345.6; 3197.4 3240.0 Young 1, which had improved nutrition, gained 837 g daily for entire more than groups 2-a, by 124, 161 170 (B> 0.999), respectively. With a high meat, there dramatic increase improvement quality meat. Moreover, cost output reducing economic efficiency livestock breeding increasing. Nutritional has differentiated effect development individual organs tissues. tissue parts carcass with insufficient delayed varying degrees.
