Abstract：The aim of this experiment was to investigate the efect of adding forsythia（Forsythia suspensa） on alfalfa （Medicago satira L.）silage. Early-flowering alfalfa was used as the raw material，and four treatments were set up，adding 5% （ G1） ， 7.5% （ G2） ， 10% （ G3） of fresh weight of forsythia and no addition control （CK）with 3 replications for each treatment，and the indices were evaluated after 60d of silage fermentation. The results showed that the organoleptic scores of the treatment groups were allin the second level of good， which was better than the third level of medium in the CK group. The crude fat content of the G1 and G3 groups was significantly higher than that of the CK group P<0.01? ，and the crude protein content of the G3 group was significantly higher than that of the CK group （ P<0.01 .The contents of acid detergent fibre and neutral detergent fibre were reduced in the treated groups，and the relative feed value scores were higher than those of the CK group. pH was significantly lower in the G1 and G3 groups than in the CK group （ （P<0.01） ，and the contents of lactic acid and acetic acid were significantly lower in the G1 group than in the CK group （ P<0.01? ） Aerobic stability was significantly better in the G2 group than in the CK group （P<0.05） ，aflatoxin and vomitoxin contents decreased with increasing forsythia addition.In conclusion，the addition of forsythiacan improve silage quality，increase aerobic stability and reduce mycotoxin content，and the addition of 10% forsythia to alfalfa silage has the best effect.

紫花苜蓿（MedicagosativaL.）是多年生豆科植物，因其營養(yǎng)價值高，在全球范圍內(nèi)被廣泛種植，被譽為“牧草之王”[1-2]。（剩余12299字）
