ABSTRACT
This study was conducted in order to determine the effects of different doses of resveratrol and curcumin added to the diet of broilers on the fatty acid profile of drumstick meat, and the microbial load and physicochemical criteria in drumstick and breast meat. In the study, a total of 200 male broiler chicks at the age of one days were equally distributed into five groups. The treatments consisted of a basal diet (Control) and the treatments, which added the following amounts of additives to the basal control diet (R250) 250 mg kg-1 resveratrol, (R500) 500 mg kg-1 resveratrol, (C250) 250 mg kg-1 curcumin, and (C500) 500 mg kg-1 curcumin. It was found that resveratrol and curcumin significantly decreased the counts of total mesophilic aerobic bacteria (TMAB) (8th day), Lactobacillus spp. (6th day) and Lactococcus spp. (8th day) in drumstick meat. In breast meat, decreases were observed in the counts of Micrococcus/Staphylococcus (4th day) in the C500 group, and Enterobacteriaceae (8th day) in the R500 and C500 groups. The TBARS value in drumstick meat decreased significantly in the R250, R500 and C500 groups on the zeroth day. Myristic acid, myristoleic acid, γ-linolenic acid, unsaturated fatty acids (ΣUFA), and medium chain fatty acids (MCFA) percentages of total fatty acids in drumstick meat were found to increase in the R250 group according to other groups. In conclusion, it was observed that resveratrol and curcumin added to the diet at variable levels affected the meat in terms of microbial and fatty acid profiles, while the effect was limited effectiveness on physicochemical parameters.(AU)
