Utilization of locally sourced feed ingredients and their influence on the growth performance of broiler chickens (Gallus gallus domesticus): A study in support of the school’s chicken multiplier project
Abstract
This study evaluated the utilization of locally sourced feed ingredients and their effects on the growth performance of broiler chickens (Gallus gallus domesticus) to support the development of nutritionally adequate and cost-effective feeding strategies for institutional and smallholder poultry systems, particularly backyard raisers. Growth performance indicators—including feed intake, average daily gain (ADG), and feed conversion ratio (FCR)—were assessed across different dietary treatments. Results showed that feed type significantly influenced broiler performance during the early to mid-growth stages (Days 8–28), as indicated by consistently significant ANOVA results (p ≤ 0.024 to p ≤ 0.001). Broilers fed commercial diets (T2 and T3) exhibited higher body weight gains and superior FCR compared with those fed the CSU-formulated grower broiler feed (T1), reflecting the higher nutrient density and digestibility of commercial formulations. Despite these differences, the CSU-formulated feed supported satisfactory and progressive growth, particularly during the initial growth phase (Days 8–14), with adequate body weight gain and acceptable feed efficiency. Notably, during the later growth phase (Days 29–35), differences in body weight among treatments were generally not significant (p > 0.05), indicating comparable final weights between birds fed the formulated and commercial diets. Biologically, these findings demonstrate that the CSU-formulated grower broiler feed can sustain sufficient growth and feed efficiency. Although performance was inferior to commercial feeds in certain parameters, its local availability, lower cost, and adaptability make it a practical alternative for resource-limited and small-scale poultry operations. Further improvements in protein quality, energy density, and nutrient digestibility may enhance its performance and narrow the gap with commercial diets.
