The hay production was 15 525.8kg/hm2, the stem-leaf ratio was 1： 1.62. The leaves didn＇t easily fall off when making hay. The tannin content was 0.02% and 0.93% during the branching period and early flowering period respectively. When the ruminants were fed by fresh forage, they did not occur bulging disease. When the Holstein was fed by hay, its milk yield, milk fat and milk pro.tein were increased by 0.21%, 0.35% and 0.24% individually compared with the Medicago sativa L.sv. ＇Xinjiang Daye＇ .
