Abstract

According to the results of control weigh inclusion of this preparation in the structure of the main diet of calves within 90 dais promoted the increase of prolethal weigh of animals for 6,42% (Р<0,01). On a surface and on depth of carcasses the smell was specific, peculiar to fresh meat of undergrowth cattle,when pressing by a finger the pole guickly leveled. In an extract from the coled - down meat of experimental animals pH was wihin 5,74±0,05 and pH extracts of calve meat of the control group was 5,81±0,08. In the meat of the calves in both groups aminoammoniac nitrogen contained from 0,86,16±0,01 to 1,20±0,02 mg. Experimental animals had dense intermal end extemal fa, practically didn’t differ from that animals of the control group. Masses of the main subproducts of the animals of the experimental group in comparison with the control analogs, were higher in average: hearts - for 3,34 (P<0,05), lungs - for 3,71 (P<0,05), liver - 3,18 (P<0,05), kidneys - for 3,14 (P<0,05), spleens - for 3,67% (P<0,05) respectively. In mucles of a sholder blade beit and back area experimental calves in comparison with control ones also had a content of fat and protein more, in average for 0,25% and 0,51%.
