Abstract: Influence of propolis extract on meat performance of chickens’ hybrid combination Hubbard JV was evaluated in this experiment. The feed mixture has been made without addition antibiotic preparation and coccidiostats. However, propolis extract was added to the feed mixtures of experimental groups during the whole fattening period in followed amounts: 150 mg kg-1 (1st experimental group – E1) and 450 mg kg-1 (2nd experimental group – E2). Fattening lasted 42 days. Live body weight increased by 7.63 g in E1 and by 14.13 g in E2 compared with control group (1507.37 g). Carcass body weight was higher in experimental groups (1022.37 g – E1 and 1019.75 g – E2) compared with control group (1005.12 g). The weight of giblets was lower in experimental groups (117.79 g – E1 and 117.16 g – E2) compared with control group (119.06 g). The carcass yield of chickens was higher in E1 (75.27%) compared with control group (74.92%), Carcass yield of chickens was higher in E1 (75.27%) compared with control group (74.92%) but E2 (74.76%) was lowest. and there were no significant differences (P ≥ 0.05) among the groups.
Propolis extract did not influence the meat performance. Slight increase of live body, resp. of carcass body weight at the end of fattening can have a positive effect on the overall economics of chicken meat production.Based on the results, propolis extract is available supplement for chickens fattening.
