This paper presents the researches performed on 2 groups of 20000 broiler chickens - a control group and an experimental group – in order to assess the effect of NOACK AC PD2 product containing organic acids (acetic, lactic, propionic and formic acids). The product was administered in chickens’ feed at a concentration of 3 kg/t during their entire life time – 42 days - till the slaughter. As a result, it was noticed a reduced chicken morbidity of 6 % in the experimental group compared with 11.6 % in the control group; and the lethality rate amounted to 1.9 % in the experimental group and 2.7 % in the control group. At the end of experiments the body weight of chickens from the experimental group was by 110 g higher than the weight of the chickens from the control group (p<0,001). The investigated biochemical indices of the broiler chickens from the experimental group recorded an increasing trend.
