In this study, it was aimed to determine the effects of V. vinifera L seed extract against the negative effects of performance parameters, organ weights and blood parameters due to the administration of gentamycin in broilers. A total of 240 Ross 308 chickens were divided into 4 groups with 6 replications of 10 birds per cage. Treatment groups: Control group was fed a basal diet only; group V was fed a diet supplemented with grape seed extract (100 mg/kg); group G was fed a basal diet and administered gentamycin (50 mg/kg body weight intramuscularly); group V+G was fed a diet supplemented with grape seed extract, and gentamycin in levels as in group V and G. The highest weight gain and feed intake at the 3rd, 4th, 5th and 6th weeks was observed in group C, and the lowest, statistically significant, was in group G. The highest carcass weight was in group C. The highest aspartate aminotransferase and alanine aminotransferase levels were in group G. The lowest red blood cell value was in group C. Liver weight was increased significantly in group G. In this study, it was observed that the use of gentamycin harmed the health of broiler hens, but these effects could be reduced partially with the grape seed extract added to the feed. For this reason, grape seed extract may be used as a feed additive with healing effect.
