Abstract: 15 000 green-shell laying hens(148 day-old)were randomly assigned into a free range group, and 2 caged groups with low-density and high-density housing, respectively. Each group was further divided into the control(C)and taurine treatment(T)groups. All the test subjects were fed the same basic diet except that the T groups was supplemented with 0.1% taurine. After 90 days, serum, kidneys were aseptically collected. The results show that there was no significant change of serum concentrations of SCr and UA between different groups(P>0.05). Compared with free range group, serum BUN concentrations were higher both in high-density group and low-density group(P<0.05). No significant difference was observed on iNOs activities and TNF-α, IFN-γ, IL-4, IL-10 concentrations in different groups. There was no significant change of MDA content, SOD and T-AOC activity in kidney tissue under different rearing patterns(P>0.05). Compared with high-density group, the T-AOC levels in free range group increased obviously(P<0.05). The T-AOC levels of free range group and caged groups with high-density housing with 0.1% taurine increased significantly(P<0.05). The data indicate that free range, reduced housing density and taurine could influence anti-oxidation level, regulate metabolism and protect the normal function of the kidney and thus enhance the health of laying hens.
