Abstract: In order to study the effect of defeathering on feather performance, growth performance and serum biochemical indexes of Zhedong White geese. A total of 120 120-day-old Zhedong White geese were randomly divided into control group and experimental group. The control group was defeathered only at the end of the experiment (45 d), while the experimental group were defeathered at the beginning (1 d) and the end of the experiment (45 d), respectively. The trail lasted for 45 days. The results showed that defeathering could promote the growth of feather and improve the feed conversion efficiency. Meanwhile, it could bring stresses syndrome to geese in a short time. There were significant differences in the serum level of TP, ALB, GLB, GLU, Ca and P 4 d after defeathering compared with 1 d before defeathering (P<0.05). There was no significant difference in the serum activity of AST 4 d after defeathering (P>0.05). Serum level of of BUN and serum activity of transpeptidase, ALT and ALP were not significantly changed before and after defeathering (P>0.05). In conclusion, it's feasible to defeather in 120-day Zhengdong White geese. At the same time more attention should be paid to the feeds and managements during the first week after defeathering.
