A total of 192 one day old Sichuan bone-black chickens were sampled and randomly allotted to four dietary treatments (12 birds per pen with 4 pens per treatment); the experiment period were 56 days. After determining the appropriate treatment dose, we studied further the effect on these traits by adding Rare-earth, Chitosan and Rare earth-chitosan, separately. The further study included 192 one day old Sichuan bone-black chickens, sampled and randomly allotted to 4 dietary treatments, 12 per pen with 4 pens per treatment and period were 56 days. The results showed that Rare earth-chitosan significantly elevated the average weight and average daily gain in Sichuan bone-black chicken and the fitting addition dose was 0.10%. As to the serum components, both the Rare earth-chitosan and Rare-earth, improved the serum of calcium, decreased the concentration of serum cholesterol and alkaline phosphatase (p<0.05) and the Rare earth-chitosan treatment had better results. Based on these results, we concluded that the fittest addition dose of Rare earth-chitosan is 0.10 %; the effects of Rare earth-chitosan on growth performances and Serum components in Sichuan bone-black chicken are better than adding Rare-earth and Chitosan separately.
