Abstract

The current study aimed to assess the impact of replacing yellow corn with orange peel by-product in broiler diets. A total of 500 male day-old Arbor Acres chicks were randomly assigned to four treatment groups, each consisting of 125 chicks (25 chicks per replicate). The first group (control) received a standard diet, while the second, third, and fourth groups were fed diets in which yellow corn was replaced with orange peel by-product at 15% (OP15), 20% (OP20), and 25% (OP25), respectively. The trial lasted for 35 days. The key findings were as follows:
1.Chicks in both the control and OP15 groups showed higher final live weights and better overall feed conversion ratios (FCR) compared to the OP20 and OP25 groups.
2.No treatment had any significant effect on carcass characteristics.
3.All dietary treatments improved the digestibility of ether extract (EE) compared to the control.
4.Blood total cholesterol levels were improved in group of OP20 without significant variations to OP15 and OP25, while control group recorded the highest level.
5.All experimental groups recorded gradual enhancement in economic efficiency comparing to control.
It could be concluded that orange peel by product (OP) could be a good replacement of yellow corn and it's level may be reach 15% replacement of corn without any adverse effect on broilers productive performance.
