Abstract: This experiment was conducted to study the effect of different rearing conditions of indoor and outdoor in winter and summer on growth performance and immune function of Heijiao MA chicken.In the winter and summer, 180 Heijiao MA chicken with the age of 35-day-old were chosen and randomly divided into two groups with three replicates per group and 30 chickens per replicate.The Heijiao MA chicken were reared at outdoor and indoor, respectively, and at 49, 63, 77, 91 days the immune organ indexes, serum antibody titers and growth performance were measured.The results showed that:①Whether it was winter or summer, the body weight of Heijiao MA chicken rearing at indoor were higher than that of outdoor, and the difference was significant at experimental stages in winter (P<0.05).There was significant difference only at 77 days old of Heijiao MA chicken in summer (P<0.05), the rest were not significant (P>0.05);②The ADG of outdoor group in summer was higher than that in winter, while the F/G of outdoor group in summer were significantly lower than that in winter (P<0.05).The ADFI and ADG of indoor group were not significantly different between winter and summer (P>0.05).③On immune function, immune organ indexes and ND antibody titer of Heijiao MA chicken of indoor group in winter were higher than outdoor group, while part of immune organ indexes, AI (H5) and ND antibody titers of outdoor group in summer were higher than that of indoor group;And ND and AI (H5) antibody titers in winter were higher than summer.In conclusion, The climate and season were major factors to influence the growth performance and immune function of Heijiao MA chicken.

Key words: Heijiao MA chicken; season; indoor and outdoor rearing; growth performance; immune function
