Technological justifi cation of organic products production in dairy cattle breeding in Donbass
Recently, the issue of increasing the production of organic products in animal husbandry in the Russian Federation has become increasingly relevant. The purpose of the work was the technological justifi cation of organic milk and beef production in the Donbass region. The research results indicate that such production is possible with a profi tability level of 50–70 % or more when using local dairy cattle breeds with milk yields per lactation of 4500–5000 kg and pre-slaughter weight of 18-month-old steers of 450–460 kg using specialized animal feeding systems developed on the basis of factorial algorithms taking into account the base of local natural feeds. In comparison with milk produced using industrial technology, organic milk has a higher dry matter content by 2.0 abs.%, fat by 0.3 abs.%, protein by 0.1 abs.% with an advantage in the amount of essential amino acids (lysine, leucine and isoleucine), which determines its higher organoleptic assessment for smell and taste by an average of 1.3 points or 40.6 % (p < 0.05). The scheme of organic beef production in dairy cattle breeding based on the maximum productive use of dry matter in feed by steers allows obtaining their slaughter weight at 18 months at the level of 257.5±3.95 kg, slaughter yield of 57.4 %, carcass meat weight of 199.1±2.74 kg and a high meat yield of 78.7 %. At the same time, organic beef differs from beef received from industrial technology in its higher content of dry matter by 0.2 abs.%, fat by 0.4 abs.%, protein by 0.35 abs.%, lysine by 0.16 abs.%, threonine by 0.09 abs.%, phenylalanine by 0.12 abs.%, which results in a higher organoleptic assessment of muscle tissue and broth by an average of 0.6 points or 8.5 % (p < 0.05) and 0.3 points or 4.3 %, respectively.
