Medvid S. Metabolism, Resistance and Productivity of Poultry under the Influence of Nanotechnological Microelement Citrates.

The thesis aims at studying the impact of nanotechnological aqua citrates of microelements on metabolism, resistance and productivity of poultry. Аn optimum amount of microelements (Fe, Cu, Co, Mn, Zn, I) in the form of aqua citrates in the diets of broiler chicken and quails has been determined. The first series of tests, aimed at determining the most tolerant amount of nano technological citrates of microelements (Ferum, Cuprum, Cobalt, Manganese, Zinc and Iodine) in poultry diet, has been conducted in six groups of broiler chicken (15 birds per group) of ROSS-308 crossbreed, starting from the age of 10 days old. Control group (C) birds were fed complete feed (CF) with standard mineral premix (SMP) which contained research proven amounts of the six essential microelements (Fe, Cu, Co, Mg, Zn, and I) in their inorganic forms. Instead of molecular forms of microelements, test group birds (D1-D5) were fed water and a complex nanotechological preparation of the same elements. First test group chicken were fed aqua citrates of biogenic elements in the amounts equaling 100% of their content in SMP for the first group, 75% for the second group, 50% for the third group, 25% for the fourth group and 10% for the fifth group. The second series of tests has been conducted on Pharaoh breed quails. Test group quails were fed water and smaller amounts of microelements as compared to broiler chicken, in particular 50, 25, 10 and 5% of their content in SMP for this type of poultry.
