This article presents results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
The experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production
n the article we have presented the results of the influence of ultrasonic processing on quality of model meat systems. We have also determined optimum parameters of ultrasonic processing
There are the results of the influence of thermal bacterial sanitation on the quality of goat's milk during the reservation. The optimum parameters of bacterial sanitation adjusted for the maximum preservation of cheese's suitability are defined
