Abstract. The diet of replacement young animals having feed additive Sorbitox and Probitox in the amount of 0.50 kg/t of feed made it possible to obtain the uniformity of the group that is higher than the control by 5.3-7.3 %, the safety of the livestock - by 1.5-2.5 % by the age of 18 months. The assessment of the development of the internal organs of birds before they were moved to the "young" group was better in the group with Probitox. The weight of spleen was 17.9 % more, the liver - 25.4 %, the heart - 25.4 %, the muscular stomach - 21,1 %. However, the length of the intestines in birds with the addition of Sorbitox exceeded the control group by 10.8 %, while with Probitox only by 6.3-7.4 %. Complex sorption-probiotic feed additives in the diet of replacement young animals stimulated all types of metabolism in the body, especially protein metabolism. In the group with Probitox, these changes were the most pronounced in comparison with Sorbitox. During the growing period, feed costs for growing one head decreased by 6.9 % with the addition of Sorbitox and by 12.8 % - with Probitox, payment for feed by products increased by 6.6-14.0 %, profitability of production increased by 5.5 and 7.8 % respectively.
