- The aim of this study was to evaluate the effect of Lactobacillus acidophilus (LAC), exogenous enzymes of ZAD® (exogenous enzyme preparation) or their combination on feed conversion, and dressing of rabbits fed different treatments of sugarcane bagasse (SCB). Five rations were allotted randomly to five groups of New-Zealand White (NZW) rabbits (n=10) with initial live body weight of (838±42.4) g and 5 weeks of age. Rabbits were fed on diets with different sources of fiber as follows, (i) a control diet composed of 100% berseem hay and 0% SCB, (ii) 50% berseem hay and 50% untreated SCB (USCB), (iii) 50% berseem hay and 50% SCB treated with L. acidophilus (LAC), (iv) 50% berseem hay and 50% SCB treated with ZAD® (ZAD), and (v) 50% berseem hay and 50% SCB treated with a combination of LAC+ZAD® (LZ). Treatments of SCB with L. acidophilus, ZAD® and LAC+ZAD® had the highest feed conversion ratio than both USCB and control. The dressing percentage of rabbits that fed the LAC and LZ diets was higher (P<0.05) compared with that in the other groups. Performance index (PI) for LAC group was improved (P<0.05) compared to that for the other groups; however, PI for USCB group was the lowest (P<0.05). It could be concluded that treating SCB with L. acidophilus, exogenous enzymes of ZAD® or their combination improved feed conversion and performance with more positive effects with L. acidophilus than the other treatments.
