Effect of Increasing Protein Percentage Feed on the Performance and Carcass Characteristics of the Broiler Chicks

Abstract: The growth of broiler chickens on diets containing various levels of protein percentage diet was evaluated. Groups of broiler chicks were fed on diets containing 15, 23 and 35% protein diet for 4 weeks where, 15% is control group. As the level of protein percentage increased, weight gain and FCR (Feed Conversion Rate) did not increased. However, when diets were changed to the standard diet, compensatory growth was observed. In this study, diets were formulated with an isocaloric metabolizable energy. Chickens were fed on protein containing diets for 4 weeks. In each group was comprised of 5 animals. Birds feed on 23 and 35% protein diets the birds show increased in weight gain compared with chickens of control group. Experimental 23% protein diet was found to be optimum for birds showing significantly higher FCR in comparison to those birds with control and 35% protein dietary uptake. It was hypothesized that the optimum growth in minimum time incorporating protein percentage would provide a more sensitive assessment of nutritional status.
