Abstract: By detecting the immune function indices of 30 cashmere goats in the condition of eonfinedness and 30 ones in the condition of grazing,the results showed that comparing with the confinedness group, the positive rate of T-lymphocytes in blood had not significant difference （P〉0.05） in the grazing group. Neutrophilic granulocyte phagocytosis function was significant higher （P〈0.05）. The transformation index of lymphocytes was enhanced and there was significant difference （P〈0.05） in the grazing group. In blood, the content of CD4^＋ molecule was much higher while the content of CD8^＋ had not significant difference. CD4^＋/CD8^＋ of the grazing group was notably higher （P〈0.01）. E-C3 bRR rosette rate and E-ICR rosette rate of grazing group were significant higher （P〈0.05） than the confined group. The leukocyte count, basophile granulocyte numbers and Monocyte numbers of the grazing group were significant different （P〈0.05） compared with the confined group （P〈0.05）. The count of segmented and band neutrophilie granulocyte both had notable difference （P〈0.01）. Serum total protein and Globulin were significant higher of the grazing group （P〈0.05） except albumin. The content of serum nitric oxide （NO） in grazing group was significant higher than the confined one （P〈O.05）. This experiment indicated that the immune function of cashmeres in the condition of grazing were higher than the confined group.
