The main objectives of this study were the partial substitution of corn and soybean meal with dried distiller’s grains with solubles (DDGS) and Allzyme SSF® supplementation in growing-finishing rabbit diets studying the effect of these diets on rabbit’s performance. The feeding trial was performed on 72 rabbits of both sexes, equally allotted into six equal groups (12 rabbit/ group) in a complete randomized design to evaluate six experimental diets varied basically in the levels of enzymatic complex supplementation (0 or 0.02 %) and DDGS inclusion (0, 10, or 20 %) in 2 x 3 factorial design. Rabbits were allowed free choice access to feed and water from 54th till 91th day (slaughtering age). No statistical significant difference was found for average weight gain (AWG) (P ≥ 0.05), while high significant increase in average feed intake (AFI) (P ≤ 0.05) observed in DDGS-containing compared to DDGS-non containing diets. No significant difference was recorded for average feed conversion ratio (AFCR) (P ≥ 0.05) among all diets except for the higher DDGS inclusion rate without Allzyme SSF® supplementation the AFCR was significantly impaired (P ≤ 0.05) compared to DDGS-non containing diet. In conclusion, rabbits fed on DDGS-containing diets in this trial consumed significantly more food relative to their final body weight gain, resulting in lowered feed efficiency. |
