Summary. In modern poultry farming in the conditions of high market prices for feed raw materials, one of the important tasks is to increase the digestibility of feed nutrients. To solve this problem, biologically active substances are currently used, which, in addition, contribute to improving feed conversion. Organic acids are among the effective, affordable and safe substances. Search and testing of new, inexpensive and environmentally friendly biologically active substances that enhance the productivity and safety of poultry is an urgent task. Under the conditions of «Amursky» poultry farm, we studied the influence of acidifiers Acidomyx AFG and Ultracid InU Plus on meat productivity and safety of broilers. The economic efficiency of use of the studied acidifiers was also evaluated. Studies have shown that the use of acidifiers Acidomyx AFG and Ultracid InU Plus in dosages of 0.3% in the first ten days of cultivation and 0.2% in the rest of cultivation period had a positive effect on meat productivity, safety, feed costs per head and 1 kg of live weight gain. The chickens in the first experimental group receiving Ultracid InU Plus supplement were superior to chickens from the control group in terms of live weight at the age of 41 days by 15.5%; daily average growth – by 15.9%; safety – by 3.8%; feed costs for the growth of 1 kg of live weight decreased by 17.5%. After feeding of broilers from the second experimental group with Acidomyx AFG acidifier, an increase in all productivity indicators was also noted: live weight at 41 days of age – by 16.5%; daily average growth – by 16.9%; safety – by 3.5%; and feed costs per 1 kg of increase in live weight reduced – by 18.1%. Comparing feeding efficiency of the studied additives with each other, we found that the zootechnical indicators of chickens were at the same level. However, the cost of 1 kg of Acidomix AFG acidifier is 34.9 rubles lower than the cost of Ultracid InU Plus, which led to the conclusion that the use of Acidomyx AFG acidifier is more economical.

Key words. Broiler chickens, feeding, acidifier, Acidomix AFG, Ultracid InU Plus, organic acids, feed conversion, daily average gain, slaughter weight, safety.
