Action of New Feeding Additive to Meat Productivity and Quality of Bull-Calves Meat

Abstract

As a result of the researchers found a positive effect of new feed additive on the growth rate, the qualitative indicators of meat fattening. It was found that the effect of feed additives on the productivity increased with increasing doses of feed additives from 100 to 300 g per head. Thus, at the age of 18 months, the bulls of the first experimental group surpassed the control analogues by 3.86, the second – by 5.53 and the third – by 6.42% and the average daily increase by 7.50, 11.63 and 12.45%, respectively. On the basis of the control of the slaughter was revealed that the weight of the paired carcasses in calves from the experimental group was higher than that of peers, not consuming the Supplement, of 5.82-of 9.91%, and their output is up 0.09 to 0.86 percent. At the output of the pulp of the bulls of the experimental groups exceeded the control analogues by 0.72-1.05%. The meat index of their carcasses was, respectively, higher by 0.25-0.36. In average the sample of the flesh of the carcasses of young animals who consumed the study Supplement contained more protein compared with the control 0,28-0,57% fat, respectively 0,68-1,19%. The influence of feed additive and on the content of amino acids in meat was revealed. Thus, essential amino acid tryptophan in the longest muscle of the back of the bulls of the experimental groups was higher by 1.58 – 2.87% and protein quality index-higher by 0.37-0.63. The flesh of the carcasses of calves of the experimental groups had higher technological properties. The moisture-retaining ability of their longest back muscle was higher than that of analogues of the control, by 2,05-2,22%, the fading – lower by 2,04-2,41%. In the body of young cattle, consuming feed additive, protein was postponed more than in control, by 8,67-14,85% and fat – respectively by 11,96-21,44%. The conversion rate of protein they were higher by 0.78-0.86%, energy - respectively 0.67-1.06%. The level of profitability of beef production in the experimental groups was higher than in control at 4, 18-of 1.29%.

The effect of mineral complexes on the growth intensity of young bulls for sustainable agriculture

“…Such substances include trace elements. Balancing rations for missing minerals can significantly increase the efficiency of livestock production [8,9,10,11,12].…”

Technology for obtaining fodder additive for animals and birds

“…Based on the above existing problems for the country's agricultural sector, an innovative technology for obtaining a feed additive from unused resources and reserves of the agroindustrial complex is required. This problem is urgent for peasant farms, agro-industrial firms, which also face similar natural, managerial, organizational, technological difficulties, now having factors and environmental conditions, unforeseen emergencies and natural, weather anomalous phenomena that impede the production, preservation, storage and providing livestock and poultry farming with a fodder base [6][7][8][9][10][11]. The purpose of this work is to analyze the existing problem, scientific and technical search for the developed devices, identify existing known analogues, select a prototype and develop an innovative technical solution with the installation of our modification for further obtaining a feed additive suitable for the morphological and functional characteristics of animals and birds.…”

The Effect of Improvac on Testosterone Level and Live Weight of Bulls

“…According to I.F Gorlov., A.A. Kaidulina [1], the determining factor defining the level of animal improvement and its meat productivity is the live weight. The results of studies by some authors show that the intensity of growth of castrated and noncastrated bull-calves of the Kalmyk breed under identical conditions of keeping and feeding is not the same in different age periods.…”
