Nutrient Digestibility and Carcass Characteristics of Rabbits Fed Yam-Cassava Peel Composite Meal as Replacement for Maize
This study was carried out to investigate the effect of dietary replacement of maize with yam-cassava peel composite meal on apparent nutrient digestibility and carcass characteristics and primal cuts of growing rabbits in 84-days (12 weeks) feeding trial. Thirty six weaner rabbits of mixed sex, strain and average initial weight of 500.89 g were randomly allotted to six dietary treatments according to live weight in a Completely Randomized Design (CRD). The six dietary treatments were formulated such that, Diet 1 (T1) contained maize and the proportion of maize in diet 1 (T1) was replaced with soaked and sundried yam-cassava peel composite meal (YCPCM) in a ratio of 6:1 at 20, 40, 60, 80 and 100% in diets 2(T2), 3(T3), 4(T4), 5(T5) and 6(T6, respectively. Weighed amounts of feed were served every morning while fresh, cool and clean drinking water was provided ad-libitum throughout the experimental feeding period. Routine management practices were strictly carried out. Analyzed proximate composition of the experimental diets revealed that, the diets were formulated in according with the ranges of recommendation for growing rabbits with metabolizable energy (ME) and dry matter (DM), crude protein (CP), crude fibre (CF), ether extract (EE), total ash (TA) and nitrogen-free extract (NFE) ranged of 2561.02 – 2842.38 kcal/kg and 92.41 – 92.98, 18.38 – 18.68, 12-15, 1.49 – 3.30, 11.00 – 15.08 and 42.08 47.09 % respectively. Results on apparent nutrient digestibility, carcass and primal cuts characteristics of growing rabbits indicated no significant (P>0.05) difference in all the parameters measured. This suggests that, replacement of maize with 100%YCPCM in diets of growing rabbits has no deleterious effect on nutrient digestibility and carcass characteristics of the rabbits.
