Farionik T. Veterinary-sanitary examination of beef, made in conditions of deficiency of trace elements (Fe, Cu, Mn, Co, Zn) of a forest-steppe zone of Vinnitsa area

Object of research: the metabolism of substances in the body when fed with bulls chelate compounds of iron, copper, manganese, cobalt and zinc. Purpose of research: determine feasibility of a combined feeding bulls methionine chelates compounds of iron, copper, manganese, cobalt and zinc and their influence on erythropoiesis, protein metabolism, performance, slaughter performance and meat, a veterinary-sanitary evaluation of beef and to determine its biological value. Methods of research: physiological, clinical, hematological, biochemical, organoleptic, chemical and mathematical. Scientific novelty: for the first time an effective way to improve productivity and quality bulls fattening of livestock products, available for use on farms for fattening cattle, provides for increased productivity of animals and get a beef with the best chemical properties, biological value and the physical, chemical and sanitary staff. Enrichment feed rations bulls chelates compounds in our suggested doses improves the quality of meat: slaughter increases output and carcass grade ink, the ration of nutrient parts of carcasses. For organoleptic and basic physical and chemical parameters meat animal research does not differ from controls. The flesh of the experimental animals under the influence of chelating compounds decreased the moisture content and increases the amount of protein and fat content increases B-vitamins and some minerals, increases the biological value and calorie content of meat. By conducting research calculated and set the economic efficiency of chelates compounds. The novelty of the investigations is the fact that we have carried out comprehensive studies on the chelating compounds methionine performance, veterinary and sanitary and quality characteristics of meat bulls in the region. The elements of scientific novelty are studies on the biological value of meat bulls fattening with the use of feed enriched with chelates compounds of methionine iron, copper, manganese, cobalt and zinc. Degree of introduction: develop and experimentally based production of environmentally safe products of cattle, bulls increase productivity and improve the quality of beef through the chelates compounds of iron, copper, manganese, cobalt and zinc. Sphere (field of using): veterinary medicine.
