Abstract: This experiment was to study the effects of corn germ meal in different levels on use value of finishing pigs.120 health PIC piglets aged 45 days with similar body weight （17±2.1）kg were randomly divided into 4 groups of 5 replicates for each group and 6 pigs for each replicates （male and female were the same in each replicate）.Control group was fed basic diet,group one to three were fed diets containing different amounts of corn germ meal （5%，10% and 15%） with the same concentration of the main nutrient items.The results showed that compared with the control group，feed conversion rate in group one was no significant difference （P＞0.05），feed conversion rate in group two had a significantly decreased （P＜0.05），feed conversion rate in group three was significantly increased （P＜0.05)，average daily feed intake in control group was significantly lower than that in other groups （P＜0.05），and there were no significant differences in daily feed intake among experimental groups （P＞0.05）.With the corn germ meal level increasing，the daily feed intake was increased slightly.Group one and group two had a tendency to reduce the serum urea nitrogen content，but group two had a significant difference （P＜0.05），the content of serum urea nitrogen in group three was increased significantly （P＜0.05），there were no significant differences in serum albumin，total protein and glucose levels among all groups （P＞0.05）. Compared with the control group，the apparent digestibility of crude protein and crude fiber in group one had no significant differences （P＞0.05）.The apparent digestibility of crude protein and crude fiber in group two increased significantly （P＜0.05）,and the apparent digestibility of crude protein and crude fiber in group three decreased significantly （P＜0.05）.There were no significant differences in the apparent digestibility of crude fat and crude ash compared with the control group （P＞0.05）.Theses results indicate that the best supplementation level of corn germ meal was 10%，the anti-nutritional factors of corn germ meal may be the cellulose.
