EFFECT OF GRAPE POMACE SUPPLEMENTATION ON MEAT PERFORMANCE OF BROILER CHICKEN ROSS 308

Abstract

The aim was the evaluavate meat performance of broiler chickens Ross 308 after the addition of red grape pomace (variety Alibernet) into their diet. A total of one-day 200 Ross 308 broiler chickens of males and females were randomly divided into 4 groups (n=50): the control group (C) without additional supplementation, experimental group E1 supplemented with 1% red grape pomace per 1 kg of feed mixture, experimental group E2 supplemented with 2% red grape pomace per 1 kg of feed mixture and experimental group E3 supplemented with 3% red grape pomace per 1 kg of feed mixture. The feed mixtures were produced without any antibiotics and coccidiostatics. The fattening period lasted for 42 days. The findings of the work on the meat performance and carcass characteristics of Ross 308 broiler chickens revealed that grape pomace in amount 3% (E3 group) seems to be the most suitable feed supplement. Among the most positively affected parameters (P≤0.05) by this supplementation in comparison with control may be mentioned the live weight and breast part weight (♂, ♀ and ♂+♀). Moreover, it seems likely that any supplementation with grape pomace can positively affect (P≤0.05) giblets weight (♂+♀) and necks weight (♀ and ♂+♀).
