Abstract. One of the urgent tasks in modern poultry farming is the search and testing of new, cheap and at the same time environmentally friendly feed additives that positively affect the productivity and health of poultry [1, p. 105]. Such additives include acidifiers, consisting of complexes of organic acids and their salts. The range of organic acids used in our country is large: formic, propionic, acetic, benzoic, butyric, sorbic, fumaric, succinic, citric, ascorbic, tartaric acids and others, as well as their salts [2, p. 81. 3, p. 28. Scientific novelty. In the conditions of the “Amur Broiler” poultry farm, studies were conducted on the effectiveness of using the Acidomyx AFG organic acid. The aim of the research was to determine the rational dosage of the medication based on Acidomyx AFG organic acids, as well as to assess its effect on meat productivity and the livability of broiler chickens. Methodology and research methods. The productive effect of Acidomyx AFG was assessed by the following indicators: live weight at the age of 7, 15, 25, 35, and 41 days old; daily average increase in chickens; livestock livability, feed costs per 1 kg of live weight gain. Results. Studies have shown that the most productive was the use of the studied medication at a dosage of 0.3 % in the starter period, 0.2 % in periods of growth and finish. The effectiveness of the medication turned out to be the best in comparison with the control in terms of live weight by 15.8 %, average daily gain in chickens by 16.1 %, in terms of livestock livability by 8.9 %, and in feed costs per 1 kg of live weight gain by 0.03 kg.
Keywords: broilers, organic acids, acid binding ability, formic acid, propionic acid, chicken live weight, average daily increase, carcass weight, livability.
