- Abstract
A 5-week feeding study was conducted to evaluate the suitability of soybean chaff (SC) as a replacement for wheat offal in the diets of broiler chickens. A total of three hundred and sixty (360), 21-d-old mixed sexes, broiler chickens were weighed individually and randomly assigned to 1 of 3 dietary treatments with 8 replicate pens and 15 birds per replicate in a completely randomized design. Dietary treatments consisted of maize-soybean based diets containing 0, 50, 100% SC as replacement for wheat offal. Data generated on growth performance, blood indices, carcass yield and sensory properties of finishing broiler chickens were analyzed by ANOVA using PROC GLM of SAS (2007). Results showed that higher (P<0.05) final weight and daily weight gain were obtained in birds fed 100% SC and control diet. However, Feed conversion ratio (FCR), livability, European Production Efficiency Factor (EPEF) and European Broiler Index (EBI) were not significantly (P>0.05) affected. Birds fed 100% SC had higher (P<0.05) live weight, plucked weight, wings and empty gizzard weight compared to other treatments. Replacement of wheat offal with soybean chaff did not interfere with the organoleptic properties of broiler meat. More so, birds fed 100% SC had least cost of feed, cost of feed per weight gain and most profitable commercial value as revealed by reduced total cost of production. Therefore, soybean chaff could be used to completely replace wheat offal as dietary fibre source in the diets of broiler chickens.
