The influence of diets enriched with vitamin E and Hadox drug on the meat productivity of quails

Abstract

In recent decades, the quail industry has become a promising direction in industrial poultry farming in our country. The basis of full-fledged compound feed of meat poultry is grain cereals (corn, barley, sorghum, etc.) and legumes (soy, peas, castor-oil plant, etc.). However, due to the high concentration of lipids in the grain of some of these crops and compound feed in general if storage in conditions are violated, feeding them to quails in large quantities can lead to the accumulation of peroxides in them and activation of lipid peroxidation processes in the body. The mechanism of action of antioxidants is to activate the body’s anti-radical defense, because these drugs are able to effectively prevent “oxidative stress” by neutralizing free oxygen radicals. Without antioxidants due to the high activity of free radicals in the bird’s body the processes of oxidation of phospholipids of cell membranes are activated, which leads to the destruction of the structure of the DNA molecule and gene mutations. Therefore, natural and synthetic feed preparations of antioxidants, which differ in synergism of action with a wide range of dietary additives on metabolic processes, have become more actively used in poultry nutrition. The purpose of the research was to study the influence of barley-sorghum-soy-type diets enriched with antioxidant preparations Hadox and vitamin E on meat productivity, nutritional and biological value of meat, the state of metabolism in the body of quails reared for meat. Under the conditions of the North Caucasus the expediency of joint feeding of feed antioxidants vitamin E and Hadox to quails grown for meat has been experimentally proved and scientifically justified, when using diets based on barley grain, sorghum and soy of local production, to increase meat productivity, increase their nutritional and biological value of meat and intensify metabolic processes. Thus, in order to increase the economic effectiveness of quail meat production in the North Caucasus the formulation of compound feed based on barley, sorghum and soy of local production should be input together the antioxidant preparations vitamin E at the dose of 25 thousand IU/t of feed and Hadox at the dose of 150 g/t of feed.
