PRODUCING ECOLOGICALLY SAFE BROILER MEAT UNDER CONDITIONS OF TECHNOGENIC AGROECOSPHERE
Ourresearch is devoted tothe study of problems and ways of producing ecologically safe broiler meatunder conditions of technogenic agroecosphere. The work was carried out on thebasis of a typical Ural farm (Chelyabinsk region, Russia); the work wasconsisted of two stages. The content of chemical elements in soil, water andfeed samples was determined at the first stage; a method of reducing toxic elementsin poultry meat was tested at the second stage. The broiler chickens of the“Smena 2” crossbreed was formed in 4 groups. The 1st group was the controlgroup; the 2nd, 3rd and 4th (the experimental groups) received the basic rationof a biologically active complex of lucerne extract at a dose of 15, 30 and 60mg per one kg of body weight, respectively, beginning from the 5th day of age. Therewas a redistribution of biogenic and toxic elements in the broiler liver; the numberof biogenic elements of copper, zinc, cobalt, manganese increased by an averageof 1.42; 1.5; 3.43 and 1.92 times, respectively; the level of nickel and leaddecreased by an average of 2.37 and 2.45 times, respectively. As a result ofthe application of the biologically active complex of plant origin, it wasnoted that with an increase in its dose, the content of toxic elements (leadand nickel) in broiler meat decreased by 1.19‒1.46 and 1.89‒1.92 times,respectively, in comparison with the control group. The research results determine the possibility of testing abiologically active complex of plant origin to reduce the level of toxicelements in the composition of products obtained from other farm animals.
