Dietary cassava peel meal, methionine, and multi-enzyme supplementation in rabbits’ nutrition: effect on growth, digestibility, and carcass traits

Background This study was carried out to assess the performance indices, nutrient digestibility, and carcass trait of weaner rabbits fed diets containing cassava peel meal (CPM) supplemented with methionine (MET) and multi-enzyme (ENZ). Two hundred and forty 5-week-old growing rabbits were randomly allotted to 8 dietary treatments (10 replicates/treatment) in a factorial arrangement (2 × 2 × 2) of 2 CPM inclusion levels (0 and 35%), 2 MET levels (0.56 and 0.83%), and 2 ENZ levels (0 and 0.05%). Results The final weight gain (1563.16 g), daily weight gain (17.67 g), and feed conversion ratio of rabbits fed diet 5 (35% CPM; 0.56% MET) were significantly ( P
