Abstract: 300 Huoyan geese aged 28-day-old and weighed (1142.68±50.64) g were allotted to 3 groups. Each group had 5 replicates with 20 geese in each replicate. The 1.5%,3%,4.5% expanded blood meal were added in diets, respectively. The feeding experiment lasted for 28 days to study the effect of the different levels of expanded blood meal on the apparent metabolic rate of nutrients and the serum biochemical indexes. The results showed that: ①The apparent metabolic rate of nutrients were the highest in the group with 3% expanded blood meal. The apparent of metabolic rate of ADF,CP was significant higher in the 3% expanded blood meal group than 1.5% expanded blood meal group and 4.5% expanded blood meal group（P＜0.05）.The apparent of metabolic rate of NDF,E was significant higher in the 3% expanded blood meal group than 4.5% expanded blood meal group. There was no significant difference between the 1.5% expanded blood meal group and 4.5% expanded blood meal group（P＞0.05）.②The serum ALT,AST,ALB,GLOB and TP were the highest in 3.0% expanded blood meal group,but there were no significant difference among groups（P＞0.05）.Combined all indexes;the best addition level of expanded blood meal in the diets of the growing Huoyan geese was 3.0% in this test.
