Abstract

The study was conducted to investigate the performance of broiler chickens fed diet containing Pro-vitamin-A Cassava Leaf Meal (PVACLM) as a replacement for groundnut cake (GNC) protein. A total of 120-day-old Ross-308 broiler chicks were randomly allotted into 4 treatment groups of 30 birds per treatment, each group further divided into 3 replicates of 10 chicks per replicate in a Completely Randomized Design (CRD). The group were tagged as treatment 1 (T1) treatment 2 (T2), treatment 3 (T3) and treatment 4 (T4) at the ratio of 0%, 5%, 10% and 15% PVACLM for T1, T2, T3 and T4 respectively. Treatment 1 had no PVACLM, designated control.  The feeding trial lasted for 56 days. Results for growth parameters showed that there were no significant differences (p>0.05) among the treatment groups, except in feed conversion ratio (FCR). The best feed conversion ratio (2.63) was found in 10% inclusion level of PVACLM (T3), followed by 15%, 0%, while 5% was the lowest. Least levels (36.6967 and 26.6667) of mortality were recorded in T2 and T4 respectively. Carcass characteristics shows that T4 (15%) inclusion level had better performance (p<0.05) in thigh weight (17.75 g). therefore, for efficient productivity and reduction in cost of production 10% inclusion of graded PVACLM is recommended.
