Efficacy Of Roxazyme-G On The Utilization Of Yam Peels By Weaner Rabbits

Abstract

Expcrimcnt was designed to investigate the efficacy of an enzyme-Roxazyme G on the utilization of yam peel meal by weaner rabbits. The Sun-dried yam peels replaced maize portions at 0(!/o (control diet I), 12.5% (Diet 2), 25% (Diet 3) and 50% (Diet 4) respectively and a 50g Roxazyme G inclusion except in the Control diet. Thirty-six (36) purebred New Zealand weaner rabbits comprising of 16 bucks and 20 does between 1) 55g to 1202, 50g average initial body weight were used for the experiment such that three caged rabbit served as 1. replicate with three replicates per treatment (Diet).
The feeding trial lasted for 70 days. Result showed lack of significant (P>0.05) differences among the performance traits monitored. Results indicated tremendous improvement in the average final weight, feed intake, water intake, body weight gain and feed efficiency as the level of Yam peel meal inclusion increased in the diets. Result of digestibility trials also indicated linear improvements as the level of fibre or yam peel, meal inclusion in the diets increased, Digestibilities of crude protein, crude fibre, ether extract and nitrogen free extract were significantly (P<0.05) different among the dietary treatments with higher digestibility obtained, among the diets with, yam peel meal and .R9xazyme G inclusion, Inclusion of Roxazyme-G may have hydrolyseed; the, :- non-starch polysaccharides thus increasing the nutrient absorption of the diets: t9 a comparable level with containing maize grains.
