The use of agro industrial by-products in the diet of grower Turkeys

Abstract

An experiment was conducted to evaluate the response of grower turkeys to diets containing different agro industrial by-products. A total of 120grower turkeys were used for this study. Four experimental diets were formulated and designated as T1, T2, T3, and T4. T1 (control diet) contained none of the agro industrial by products used while T2, T3 and T4 contained15% each of Wheat offal, Maize offal, Rice offal respectively. The turkeys were randomly allocated to four experimental treatments of thirty birds per treatment while each treatment was replicated three times (3) with ten (10) birds per pen in a completely randomized design. The result of growth performance revealed that average feed intake, average weight gain and feed conversion ratio of turkeys fed the control and 15% Wheat Offal diets were not significantly different (P>0.05). The result of carcass characteristics and organ weights followed similar trend. Turkeys fed 15% Maize Offal and 15% Rice Offal diets recorded the lowest values (P<0.05). There were no significant differences (P>0.05) in all the haematological parameters and serum biochemical indices measured except PCV which decreased across the treatment groups. It was concluded that 15% wheat offal can be included in the diet of grower turkeys without adverse effect on growth performance, carcass yield and health status of birds.
