Abstract
Seventy Five (75) day-old broilers randomly allotted into five treatments with 3 replicate each containing five birds where used to evaluate the effects of urea treated Rice Milling Waste (UTRMW) and untreated Rice Milling Waste (UNTRMW) on the performance and internal organ characteristics of broiler chickens. Five experimental diets T1, T2, T3, T4 and T5 containing 0% UNTRMW, 10% UNTRMW, 15% UNTRMW, 10% UTRMW and 15% UTRMW respectively were formulated. Complete Randomized Design (CRD) was used and significant means were separated using Duncan Multiple Range Test. The results of the proximate composition of the diets showed an increase in the crude protein in T4 and T5 due to non-protein Nitrogen contribution from urea. In the starter phase, weekly weight gain and feed cost per Kg gain were highly significant (p< 0.01). Final weight, total weight gain, daily weight gain and FCR were significant (p< 0.05). At the finisher phase as observed from Table 4, Final weights, weekly weight gain, Total feed intake, FCR and Feed cost/Kg gain were highly significant (p<0.01).Daily feed intake was significant (p<0.05).As for the internal organs, spleen and intestine weights were highly significant (p<0.01) while liver and gizzard weights were significant (p<0.05). T2 was better in feed cost per kilogram gain (N) at the starter phase. T4 (10% UTRMW) had the best live weight apart from T1. T3 had the highest gizzard weight. 10% dietary level of inclusion of UTRMW and levels below 10% of UNTRMW is recommended in broilers diet, and 15% level of inclusion of UNTRMW is recommended if the sale of gizzard is priority.
