Abstract: Eighty rex rabbits with age in 40－ 50 days were divided into 4 groups to study the effect of additive al-licin level (0，0.02 %，0.04%，and 0.06%)to their production performance and serum biochemical index. Resultsshowed that there was significant difference in daily gain between the group of 0.04% allicin and control (P<0.OS )，but no significant difference in other two levels. Additive allicin could promote the growth reduce diarrhea and im-prove the feed digestibility for rex rabbits. Experiment indicated that 0.04% of additive allicin improved the produc-tion performance，but there was no significant effect on digestive enzyme activity on rex rabbits.

Key words: Allicin, Rex rabbit, Production performance, Digestive enzyme activity
