The research undertaken in order to determine the optimal dose and efficacy of the use of additives "Primix-Alfasorb" and "Primix-Bionorm-K", was conducted on broiler chickens of the meat hybrid COBB-500, in the laboratory of the Department of General Animal Husbandry of the State Agrarian University of Moldova, in the period from 11.18.2011 to 30.12.2011. To conduct the experiment on the basis of analogies, five groups of clinically healthy one day-old chickens of the Cobb 500 hybrid, 21 head each, were formed. The first group served as the control group, and received the basic diet; in the fodder for the second and the third groups, the experimental ones, the enterosorbent "Primix-Alfasorb" was added – 0.2 and 0.4 kg/t respectively; in the fodder for the fourth group the probiotic preparation "Primix-Bionorm-K” in quantities of 0.2 kg/t was added, and the fifth group received both probiotic and the adsorbent in quantities of 0.2 kg/t. In the trial the average live weight of the broiler chickens, which received the supplement "Primix-Alfasorb" in quantities of 0.2 and 0.4 kg per 1 t in EG1 and EG2, amounted to 1995.62 g and 2060.10 g respectively, with an average daily gain of 46.37 and 47.89 g, which was higher than in the control group by 2.20 and 5.55%. The supplementation of the fodder for the broiler chickens with the additive "Primix-Bionorm-K" at the level of 0.2 kg/t, increased the live weight of the broiler chickens in the EG3 by 10.40% (P . 0.01), the average daily gain by 10.62%, while the cost of the fodder per 1 kg of gain decreased by 7,94% compared with the control group. When both "Primix-Alfasorb" and "Primix-Bionorm-K" were added, the broiler chickens’ live weight in the EG4 in the scientific and economic trial, was of 1967.95 g, which was higher than the same index in the control group by 0.70 %. It was determined, that the optimal rate of enterosorbent "Primix-Alfasorb" input in the diets for broiler chickens was of 0.2 kg/t, and of the "Primix-Bionorm-K" of 0.2 kg/t.
