The purposes of this paper was to examine the effects of sprouting corn bran on growth performances, nutrient apparent digestibilities and meat quality of meat rabbits. A total of 300 healthy 39-day-old weaned rabbits (half male and half female) were randomly divided into five groups (groups Ⅰ,Ⅱ,Ⅲ and Ⅳ) according to their body weight and gender. Each group contained 60 repeats, one rabbit for each repeat. Five groups were fed diets containing different proportions of sprouting corn bran (0, 6%, 12%, 18% and 24%, respectively). The pre-feeding period was five days and the experimental period was 50 days. The results showed as follows: 1) the final weight and average daily weight gain in groups Ⅲ and Ⅳ were significantly lower than those in control group and groupsⅠand Ⅱ(P<0.05); the final weight and average daily weight gain between control group and groups Ⅰ and Ⅱ had no significant difference (P>0.05); the feed/gain in group Ⅲ was significantly higher than that in control group and groups Ⅰ and Ⅱ(P<0.05), the feed/gain in group Ⅳ was significantly higher than that in control group and groups Ⅰ, Ⅱ and Ⅲ(P<0.05), and there was no significant difference in feed/gain among control group and groups Ⅰ and Ⅱ (P>0.05). 2) Compared with the control group, when adding sprouting corn bran, dry matter apparent digestibility gradually decreased, group Ⅳ was the lowest, and was significantly lower than control group and other experimental groups (P<0.05). There was no significant difference among other experimental groups and control group(P>0.05), but higher than that in group Ⅳ; the apparent digestibility of crude protein was significantly lower than that in control group (P<0.05), and there was no significant difference among experimental groups (P>0.05); the apparent digestibility of neutral detergent fiber in groups Ⅱ and Ⅳ was significantly lower than that in control group (P<0.05), but there were no significant differences between the other experimental groups and control group (P>0.05); the apparent digestibilities of crude ash and acid detergent fiber between experimental groups and control group were not significant (P>0.05). 3) The weight before slaughter and carcass weight showed no differences between control group and groups Ⅰ and Ⅱ (P>0.05), but there was significant difference between groups Ⅲ and Ⅳ (P<0.05). Semi-eviscerated ratio in group Ⅰ was significantly lower than that in other groups (P<0.05), but there was no significant difference between other experimental groups and control group (P>0.05). Considering all indices of this experiment, the most proper adding ratio of sprouting corn bran in the diet of meat rabbit is 6% to 12%.
