摘  要：
[Objective] The aim was to study the effects of Chinese medicine additive HMS on promoting the production of meat hybrid chicken and its action mechanism,so as to provide a scientific basis for the promotion effects of Chinese medicine additive on production. [Method] Meat hybrid chickens,7 day-old with similar weight,were randomly divided into four groups. And Chinese medicine feed additive HMS was added to the diet of each group at different proportions. All the chickens were weighed before the test as well as at the end of the 2nd,3rd,4th and 5th week. The feed consumption was also recorded during the test. Before slaughter,serum samples were collected from the randomly selected chickens for the determination of serum biochemical indexes. Their bursae of Fabricius and spleens were collected and weighed in order to determine the indexes of immune organs. [Result] HMS significantly reduced the feed conversion ratio(P0.05) ,very significantly reduced the feed consumption(P0.01) ,very significantly improve the content of serum high-density lipoprotein(P0.01) ,significantly increased the activity of serum alkaline phosphatase(P0.05) ,very significantly reduced the content of serum urea nitrogen and uric acid(P0.01) ,and significantly reduced the level of serum cholesterol(P0.05) . There were no significant difference between the test groups and the control group(P0.05) in the increase of immune organ indexes,but the index of immune organs has increasing trend. [Conclusion] HMS reduces feed consumption and feed conversion ratio,improves the feed utilization,and has a role in promoting production. The possible mechanism may be HMS improving the activity of serum alkaline phosphatase and the level of serum high-density lipoprotein,as well as reducing the content of serum cholesterol,urea nitrogen and uric acid in meat hybrid chickens.
