Abstract: The experiment was conducted to investigate the effect of Chinese herb feed additives on the umami substances content of mutton. 32 healthy 10-month-old Chinese Merino were randomly divided into 4 groups. The group 1 was control group which was given basal diet. The groups 2,3 and 4 were fed the basal diets added with 0.1% Chinese herb feed additiveⅠ,Ⅱ and Ⅲ,respectively. After 60 days feeding,the contents of IMP and its correlative metabolites of samples were determined by RP-HPLC method. The results showed that ATP was not detected in all of the samples. The contents of ADP, HYP and AMP were very low,and there were no significant intergroup differences (P>0.05).Three Chinese herb feed additives all could improved the contents of IMP and its correlative metabolites in different degrees. The IMP, INO and IMPc contents of group 4 were extremely significantly higher than those of group 1 (P<0.01),and significantly higher than those of groups 2 and 3 (P<0.05).The results demonstrated that the Chinese herb feed additive Ⅲ could significantly improve the flavor of mutton.
