The article describes the use of “Tseostimul” mineral additives in the diets of rabbits, based on sorbents of Khotynets minefield of the Orel district. “Tseostimul” had a positive effect on the growth of live weight of young rabbits, hematological and biochemical parameters of blood at the same conditions of feeding. The most optimal dose of “Tseostimul” for these indicators was a 3.0% to the basic diet.

Due to the growing demand for environmentally friendly products, the use of natural growth stimulants in animal husbandry has become especially relevant. Studies were conducted in accordance with generally accepted methods of zootechnical accounting, the average daily milk productivity of cows, safety, average daily and absolute growth of turkeys were determined. To assess the quality of milk, we used physicochemical and microbiological methods of investigation. The meat productivity of turkeys was evaluated by pre-slaughter weight, gutted carcass weight and slaughter yield. The use of activated zeolite in milk production technology made it possible to increase the milk productivity of cows and improve the quality characteristics of milk. The use of bentonite, poly enzyme preparation “Universal” and enzyme-mineral complex in poultry meat production contributed to an increase in the safety of turkeys, their growth rate and meat productivity.

An important direction in feeding farm animals, as well as poultry, is the use of natural growth stimulants to produce environmentally friendly products. These include enzyme preparations and mineral additives (sorbents). Their effect is expressed in the improvement of qualitative and quantitative growth indicators, therapeutic and preventive protection of the young body from path-ogenic environmental influences. The use of the poly-enzyme preparation "Universal" and the en-zyme-mineral complex helps to increase the safety and intensity of growth of their live weight, and the studied additives had a positive effect on the slaughter qualities of birds. At the same time, the best data were obtained when feeding complex preparation to broiler turkeys.
