Performance Characteristics of Noiler Birds Fed Different Levels of Protein in Semi-arid Environment

Abstract

The experiment aimed to assess the impact of varying levels of dietary protein on the performance of Noiler Chickens. A total of 120 day-old Noiler birds were randomly assigned to diets with protein levels of 21%, 22%, 23%, and 24% during the starter phase, and 16%, 17%, 18%, and 19% during the finisher phase. The diets were iso-caloric, providing 2900 kcal of ME/kg at the starter phase and 2800 kcal of ME/kg at the finisher phase. Throughout the 10-week study period, ad libitum access to feed and water was provided. The results indicated that feed intake, body weight, body weight gain, and feed conversion ratio did not exhibit significant differences (P>0.05) across the different dietary protein levels during both the starter and finisher phases. Consequently, it can be inferred from this study that the performance characteristics of Noiler birds in a semi-arid region were not significantly influenced by the varying levels of dietary protein.
