Determination of Optimum Protein and Energy Levels for Broiler Chicks in the Tropics

THREE experiments were conducted to investigate the effects of different protein levels (17, 20, 23 and 26%) energy (2800, 3000 3200 KCals/Kg diet) on performance broiler chicks in tropics. Maximum weight gains efficiency feed conversion obtained rations containing or 26% protein. As dietary level increased, there was a slight depression gain. The best 2800 diet. Feed intake observed be inversely related content, although most cases not significantly so at each series. Generally birds meet their requirements. From these studies, K Cal/Kg diet may tentatively recommended for tropical country like Nigeria.
