Abstract: The aim of this study was to explore the effects of compound probiotics fermentation feed on nutritional apparent digestibility and meat quality of Xuefeng Black-boned chicken.600 healthy and nearly 17-week-old female Xuefeng Black-boned chickens were randomly divided into five groups,with six repeats each group and 20 chickens each repeat using one-way experimental design.The chickens in control group was fed with basic diets and that in treatment groups were fed with 25%,50%,75% and 100% fermentation feed replacing basic diets,respectively.The test lasted for 35 d.The results showed that:①Compared with control group,the CP and EE apparent digestibility were significantly improved in 25% and 50% fermentation feed groups (P<0.05),while the 75% fermentation feed group showed no significant difference (P>0.05).②Compared with control group,the slaughter performance rate of 75% and 100% fermentation feed groups and chest muscle rate of 25% fermentation feed group were raised significantly (P<0.05),while the abdomen lipoid rate showed no variation in all the excremental groups(P>0.05).③Compared with control group,pH24 hvalue of chest muscle and shearing force of four treatment groups were significantly reduced (P<0.05),the L* and a* values were significantly elevated (P<0.05),and the drip loss in 100% treatment group was significantly decreased (P<0.05).④DM and CP contents of 25%,75% and 100% fermentation feed groups were improved significantly (P<0.05),and the Met,Phe,Ser and Arg in the 50% and 100% treatment groups were raised significantly comparing with control group (P<0.05).All the above results indicated that the compound probiotics fermentation feed could enhance the nutrients apparent digestibility and improve the meat quality of Xuefeng Black-boned chicken under the experiment condition,but their effect showed no proportion-depend.The optimum suitable addition in this study was 100%.
