ECONOMIC EFFICIENCY OF THE COMPLEX FODDER CONCENTRATE "TETRA-PROBIO APPLICATION FOR FEEDING OF BULL CALVES
Beef is one of the types of meat that is popular with buyers, due to its nutritional value and culinary properties. In turn, for the development of beef cattle breeding, it is important to minimize production costs while maintaining high quality meat. One of the factors affecting the cost beef is the feed ration optimization. Scientists of the Krasnodar Research Institute for the Storage and Processing of Agricultural Products developed a complex feed concentrate (СFC) «Tetra-Probio» recipe containing the oil composition of biologically active substances and the probiotic supplement. The action of СFC «Tetra-Probio» is aimed at young cattle adaptation to solid feed, metabolic processes normalization and the bull calves productivity intensification. In individual enterprise Remesnik I.V. located in the Dinskoy district of the Krasnodar region, a scientific and production experiment was conducted over 112 days for fattening Holstein-Friesian breed bull calves with the inclusion of СFC «Tetra-Probio» in the diet. It was established that the use of СFC «Tetra-Probio» in the diets of bull calves for fattening allows to increase productivity in live weight by 258 kg / 10 unit for the specified period. The additional profit is 3241.8 rubles / 1 unit for the sale of bull calves in live weight or 2333.6 rubles / 1 unit for the sale of bull calves meat in the half carcasses form. Thus, it was experimentally established that the use of СFC «Tetra-Probio» in the bull calves diets is cost-effective
