GROWTH AND DEVELOPMENT OF REPAIR YOUNG CHICKENS OF THE PARENT HERD WHEN USING PREBIOTICS IN THE DIET

Abstract

The inclusion of Salmocil F prebiotic in the diet of repair young animals in the amount of 0.60 kg,
0.80 and 1.00 kg / t of feed allowed to obtain the live weight of young animals at the age of 18 weeks at the
level of 1824.2 g in the control group, higher by 0.6% with a low rate of prebiotic input, by 5.0% with an
average and by 3.3% with a high dose of feed additive in the diet. At the same time, the uniformity of the
experimental groups of poultry was higher than the control group by 8.0-9.0%. The addition of prebiotic to
the diet of the young animals of the experimental groups increased the safety of the poultry population from
95.0% in the control group to 98.0-99.0% in the experimental groups. The development of the repair young
animals of the experimental groups was higher than the control group by the growing periods, which in turn
affected the change of the feather and the muscularity of the body. Feed costs for growing one head of
business young in the control group were 7.75 EQ and 1.05 kg of raw protein, with a low prebiot ic dosage
lower by 7.4-7.7%, with an average – by 8.8-9.0%, with a high-by 8.4-8.9%, and the payment for feed
products increased by 4.5-7.2% in favor of the poultry of the experimental groups.
Key words: replacement young growth, prebiotic, feed additive, dynamics of live weight, growth,
development, safety, costs and payment for feed products.
