Abstract

This study aimed to determine the impact of different dietary levels of lycopene or lutein on productive performance, carcass criteria of broiler chicken. A total of 210 unsexed broiler chicks (Ross 308) aged 8 days were individually weighed and randomly divided into seven homogeneous groups of five replicates with six chicks each (30 chicks/group). The chicks were given the following dietary treatments: The 1st group was fed the basal diet without any supplementation and served as a control, while the 2nd, and 3rd, 4th treatments were supplied with different levels (50, 100, and 150 mg/kg) of lycopene, while 5th, 6th, 7th treatments were supplied with different levels (25, 50, and 75 mg/kg) of lutein, respectively. Data revealed that treatment groups supplemented with different levels of lycopene and lutein had improved body weight, body weight gain, and FCR compared to the control group. Dressing percentage for birds fed a basal diet supplemented with different levels of lycopene and lutein was significantly increased compared with the control group. The opposite trend was observed for abdominal fat. In conclusion, it may be concluded that feeding lycopene and lutein to broiler chicks, especially level of lycopene (50 mg/kg) and lutein (50-75 mg/kg) diet could be effective feed additives to improve the growth performance and dressing percent of broiler chicken.
