Effect of Sumac, Yeast, and Onion on Broiler Chicken Performance

Abstract

This study was conducted to determine the effects of sumac, yeast, and onion supplementation to broiler chicken feeds on performance. Four hundred and fifty, one-day-old Ross 308 broiler chicks were obtained from Yagoo Group Hatchery in Sulaymaniyah Province and were randomly distributed into three treatment groups (150 chicks for each group) with six replicates (each 25 chicks). Chicks were raised on floor cages (210 × 200 × 100 cm). T1 (Feed with 0 mg kg-1 sumac, yeast, and onion), T2 (Feed with 10, 2 and 20 mg kg-1 sumac, yeast, and onion for every day) and T3 (Feed with 10, 2 and 20 mg kg-1 sumac, yeast, and onion for 2 days added and 2 days free in the rearing period) experiment groups were constituted. In the study, the effects of the treatments on the performance parameters were found to be statistically significant. In body weight, the highest group in terms of total body weght gain and total feed intake was T3, and it was significantly higher than T2 and control groups (p<0.001). Again, T2 was found to be significantly higher in terms of these parameters compared to the control group (p<0.001). In total, the feed conversion rate (FCR) was found to be statistically significant. While T3 had a similar FCR (1.50) to the control group, it was significantly lower (p<0.001) compared to T2 (1.68). In general, the treatments were found to have a positive effect on performance parameters.
