Abstract: This experiment was conducted to study the effect of rapeseed meal on weight gain,nutrient utilization and serum biochemical indexes of Zhedong White geese from 4 to 6 weeks.160 4-week-old Zhedong White geese were randomly divided into 4 groups with 4 replicates per group and 10 geese per replicate.The control group was fed a basal diet,and the three experimental groups were fed experimental diets which used 3%,6%,9% rapeseed meal replaced soybean meal in the basal diet,respectively.The pre-test period lasted for 7 days and the trial period lasted for 14 days.The results showed as follows:①Compared with control group,the weight gain of geese in 3%,6% and 9% groups showed a decreased tendency,but there were no significant differences among all groups (P>0.05).②The utilization of GE,CP and TP were the highest in 3% group,and extremely significantly higher than that in control group (P<0.01),also the EE utilization was extremely significantly higher than that in control group (P<0.01).With the rapeseed meal level increasing,the utilization of CF and Ca in experimental groups were decreased,and 6% and 9% groups showed a significant difference compared with control group (P<0.01).③The utilization of Asp,Glu,Ser,Ile,Leu,Phe in 3% group were extremely significantly higher than that in control group (P<0.01).Except for Val and Lys,there were significant or extremely significant differences in other amino acids utilization between control group and 6% group (P<0.05;P<0.01).The utilization of Ser,Gly,His in 9% group were extremely significantly higher than that in control group (P<0.01).④With the rapeseed meal level increasing,the serum GLU,T3,T4 contents in experimental groups were increased (P>0.05),the serum TC content in 9% group was significantly higher than that in control group (P<0.05),there were no significant differences in the contents of TP,TG,ALT,AST of serum among all groups (P>0.05).In conclusion,3% to 6% rapeseed meal replaced soybean meal in the diet of Zhedong White geese from 4 to 6 weeks was appropriate.
