Abstract

The present study was conducted to evaluate growth promoting effect of anise seed Pimpinella anisum L. in broiler chickens in terms of live body weight, carcass characteristics (traits), organ weights, production traits and mortality percentage. For this purpose, four levels with 0, 0.3, 0.6 and 0.9% of aniseed powder were administered in feed from day 0 till the end of experiment (42 days of age). Positive results were obtained specially in body weight and carcass traits like dressing percentage, when aniseed was fed by broiler chicken. This study showed a significant at P<0.05 effect of different treatments on live body weight and dressing percentage, but there was no significant at P<0.05 effects of different treatments on mortality percentage. Also, there was a significant at P<0.05 effect of different treatments on Carcass cuts: breast, thigh and back percentage, but there was no significant at P<0.05 effects of different treatments on wings, heart, liver and gall bladder percentage. According to the results obtained of this study, it can be concluded from this study that additive dietary broiler chicken with anise seed improve production traits like live body weight, body weight gain, dressing percentage, FCR and production index. However, there were not significant effect on mortality and some internal body organ percentage.
