| 3 Inner Mongolia wether with rumen fistula were used to do experiment with 3×3 Latin Square design method and study the effect of Allium mongolicum Regel and interplay of Allium mongolicum Regel and oil seed on rumen parameters such as pH, protozoa number, BCP, NH3-N, lipase activity and VFA concentration. Based on the above experiment, the feeding experiment was done with 28 Inner Mongolia wether, according to similar weight principle, 28 Inner Mongolia wether were randomly divided into 4 groups which were named control group, 4% Allium mongolicum Regel group(percent of concentrated feed, the same below), oilseed group(8% linseed+2% jute seed+2% sunflower seed), 4% Allium mongolicum Regel +oilseed group(8% linseed+2% jute seed+2% sunflower seed) respectively, during 45 days of experiment period, the blood is collected for 4 times to study the effect of the different treatments on blood special immunity, non-special immunity and splenic immunity function in sheep, the results indicated that: In rumen, pH of control group is significantly lower than that of experimental group (p﹤0.05), pH of Allium mongolicum Regel group is significantly lower than that of Allium mongolicum Regel +oilseed group (p﹤0.05); Protozoa number of experiment groups are lower than that of control group (p﹥0.05) and the difference among the experimental groups are not significant (p﹥0.05); BCP content of Allium mongolicum Regel is significantly higher than that of Allium mongolicum Regel +oilseed group (p﹤0.05), but BCP content of control group is higher than that of Allium mongolicum Regel +oilseed group (p﹤0.05); NH3-N concentration of control group is significantly higher than that of experimental group (p﹤0.05) and the difference among the experimental groups are not significant (p﹥0.05); Lipase activity of control group is significantly lower than that of experimental groups (p﹤0.05), Lipase activity of Allium mongolicum Regel +oilseed group is significantly higher than that of Allium mongolicum Regel group (p﹤0.05); volatility fatty acid concentration of control group is lower than that of experimental groups and the difference among experimental groups are not significant (p﹥0.05), volatility fatty acid concentration of Allium mongolicum Regel group is higher than that of Allium mongolicum Regel +oilseed group and the difference between the two groups are not significant (p﹥0.05). In blood, monocyte phagocyte, CD2 and CD4 of experimental groups are higher than that of control group and the difference is not significant (p﹥0.05); CD8 molecule number of control group is higher than that of experimental groups and the difference is not significant (p﹥0.05). In spleen, CD2 molecule number of experimental groups are significantly higher than that of control group (p﹤0.05), CD2 molecule number of Allium mongolicum Regel +oilseed group is higher than that of Allium mongolicum Regel group and oilseed group and the difference is not significant (p﹥0.05); CD8 molecule number of experimental groups are significantly higher than that of control group (p﹤0.05), CD8 molecule number of Allium mongolicum Regel group is higher than that of oilseed group and Allium mongolicum Regel + oilseed group, but the difference is not significant (p﹥0.05); CD4 molecule number of experimental groups are significantly higher than control group (p﹤0.05).
