The Performance Characteristics and Economic Evaluation of Weaner Rabbits Fed Varying Levels of Sundried False Yam (Icacina Tricantha) Meal

Abstract

A seven week feeding trial was conducted to evaluate the growth performance characteristics and economics of production of 15 unsexed weaner rabbits fed varying levels of Sundried false yam (Icacina tricantha) meal. Five treatments diets were formulated with diet 1 containing 100% maize as control, while in diet 2, 3, 4 and 5 Sundried false yam meal replaced the percentage proportion of maize in diet 1 at 25, 50, 75 and 100% inclusion level respectively. Rabbits were randomly assigned to the five treatment diets in a complete randomized designed (CRD) with three replicates of one rabbits each. Performance characteristics revealed that final live weight and weekly feed intake were significantly (P<0.05) influenced with highest value (2.12kg/rabbit and 407.33g/rabbit) recorded from rabbits fed 0% SDFYM comparable to (1.98kg/rabbit and 323.33g/rabbits) recorded in those fed 50% SDFYM. Avearage weekly weight gain was also significantly (P<0.05) influenced with highest value (197.00g/rabbit) from those fed 50% SDFYM. Feed conversion was lowest and best (1.28) from rabbits fed 25% SDFYM. Mortality rate was lowest (3.43%) in rabbits fed 50% SDFYM. Cost and return analysis revealed that total cost of feed consumed was least (378.24 N /rabbits) from those fed 50% SDFYM and highest in control, cost of feed per kg weight gain and total cost of production were lowest (30.50 and 2178.24 N /rabbits) from the rabbits that ate 75% SDFYM and highest in control. Income and net profit were highest (5000 and 1763.36 N /rabbits). It is concluded from this study that Sundried false yam meal is a valuable substitution for maize up to 50% in rabbit diets without any adverse effects on the performance characteristics and economic returns of rabbits.
