The effectiveness of the application of functional feed additives, in particular biological products, in the cultivation of poultry is shown. We have developed functional biological products No. 1 and No. 2 based on perlite and propionic acid microorganisms and azotobacter bacteria, and studying their effect on the change in growth rate and preservation of young quails for fattening at a dose of 2.0% by weight of feed. According to the results of the experiment, it was established that the best result compared with the control was provided by the additive (No. 1) based on propionic acid microorganisms and perlite (an increase in the average daily increase in live weight of quails by 21.0%). The use of bioproduct number 2 provided the growth rate of poultry, in comparison with the control, by 20.2% Also, feeding of symbiotic supplement No. 2 in the amount of 2.0% ensured 100% survival of young poultry, and supplements based on propionic acid microorganisms and perlite — 98.0%, which is 6.0 and 4.0% higher than the benchmark. The results show that both bioproducts have a positive effect on the growth and preservation of quails and are recommended as supplements to the complete feed throughout the fattening period.
