The main nutritional components of forage grass in alpine meadow of Tianjun Countyin Qinghai Province from 3 741 to 4 045 m were measured and analyzed. The results indicated that dry matter（DM） content was 94.60%,crude protein （CP） content was about 4.35%,crude fat（EE） content was about 0.97%,crude fiber（CF） content 28.04%,crude ash（Ash） contentwas about 7.33%,and Ca 0.8%,P 0.03%,the content of nitrogen free extract（NFE） was 53.91%; the content of dry matter（DM） of fresh grass was 87.67%,crude protein（CF） content was about 5.80%,crude fat（EE） content was about 6.32%,crude fiber（CF） content was about 22.94%,crude ash（Ash） content was about 5.90%,nitrogen free extract （NFE） content was 52.61%,Ca 1.20%,P 0.50%,the crude protein content of dry forage than fresh forage crude protein content of loss 1.45 percentage points,dry forage crude fat than fresh forage and losses 5.35 percentage points; dry forage crude fiber（28.04%） was significantly higher than that of fresh forage crude fiber（22.94%）（P<0.05）,Ca,P in the dry grass was also lower than that of Ca and P in fresh grass in animal husbandry dry matter,ash,nitrogen free extract,and the content of fresh forage is lower than that of dry grass.
