Solomon V. Clinical-experimental basement of iron and cobalt glycinates' apply for chics-broilers

Dissertation is devoted to research of iron and cobalt glycinates' influence on clinical, haematological, biochemical and zootechnik parameters of chicks-broilers. Theorethic and experimental material about current synthesis methods improvement are expounded in the scientific work; there were researhed physico-chemical and toxicological properties of iron and cobalt glycinates', their influence on clinical state and metabolism in organism of laboratory animals and chicks-broilers of Kobb-500 strain. There was shown, that improvement synthesis methods of iron and cobalt chelate compounds with glycine assists increasing pure products of synthesis reaction efficiency (for iron glycinate - 80 %, cobalt glycinate - 85 %), it is higher on 18 and 30 % comparatively to current methods. Synthesized complexes are considered to be low (iron glycinate) and moderately toxic (cobalt glycinates) compounds according to GOST 12.1.007.76, they don't cumulate in poultry organs and tissues. There was established that applying of tested organic complexes instead of traditional ferrous and cobalt sulfates in feeding of chicks-broilers influence positively on body growth, safety, feed conversion, and other economic parameters, while not changing essentially metabolism in poultry organism. Scientifically-based doses of iron and cobalt chelate compounds apply for chick-broilers were offered for production for the first time. They are: 260 mg/kg of mixed fodder for iron glycinate and 2,1 - for cobalt glycinate.
