observed after the end of the withdrawal period, as compared to the second control
group (р≤0,05).
CONCLUSION
1. The positive influence of pharmazin and tilotsiklinvet on the productivity of
broiler chickens has been experimentally proved, which is evinced in a significant
increase in the indicators of broiler chicken’s weight before a slaughter (р≤0,001,
р≤0,01), as well as the slaughter yield of poultry carcasses, in particular – the weight
of semi-dressed carcasses of birds (p≤0,05).
2. Slaughter yield of carcasses is significantly higher by 8,2% in the experimental
group of broiler chickens, which were fed with pharmazin, compared with the control;
and in the experimental group of broiler chickens, which were fed with tilotsiklinvet,a
slaughter yield was higher by 4,3%, as compared to the control group.
3. Analysis of the research results shows a significant increase in weight of the
edible internal organs of broiler chickens of the experimental group (fed with
pharmazin) compared with the first control group (p≤0,05) at the end of the withdrawal
period. In the experimental group of broiler chickens, which were fed with
tilotsiklinvet, a significant increase in liver weight and muscle part of the stomach was
observed, compared with the second control group (р≤0,05), after the withdrawal
period.
4. Pharmazin and tilotsiklinvet can serve as a substitute for feed antibiotics, and
can be used simultaneously as a preventive way to reduce a stress on the body broiler
chickens, but does not reduce the quality of products of slaughter.
