Summary. Feed additives Toxfin at the dose of 0.11 % and Probitox in an amount of 0.10 % of mixed fodder weight were tested in diets of chicken-broilers. For the period of growth and fattening the highest live weight at the age of 39 days was registered in the group with Probitox – 2346.71 g. It was higher by 6.8 % as compared with the control and by 7.3 % in comparison with the group received Toxfin. The average daily weight gain was 56.78 g in the control group, 56.47 g – in the group with Toxfin and 60.66 g - in the group received Probitox. The preservation of livestock was 91.0, 95.0 and 96.0 %, correspondingly. The highest yield of drawn carcass was observed in the Probitox group - 73.61%, which surpassed analogues in the control group by 1.41 % and in the Toxfin group by 1.26 %. In the carcasses of the control group the content of edible parts was 1175.87 g. The usage of feed additive Toxfin reduced this rate by 1.42 % due to the decrease in the weight of visceral fat by 1.12 %. Conversely, Probitox contributed to the increase in the weight of edible parts by 0.59 % as a result of growth of muscular tissue by 1.20 % and skin with subcutaneous fat by 0.14 %. Meat and bone index in these groups was 3.49, 3.50 and 3.76, respectively. With the same cost of feed per unit of live weight gain in the control group and the group received Toxfin, the addition of Probitox reduced them 6.4 %.
Keywords: chicken-broilers, live weight, preservation of livestock, meat productivity, cost of feed.
