Abstract：The experiment was to study the effect of fermented Flammulina velutiper chaff on milk production performance,nutrient apparent digestibility and rumen fermentation parameters of Guanzhong dairy goats.Seventy-five healthy central dairy goats with similar weight,age,parity and milk yield were randomly divided into five groups,with three replicates in each group and five goats in each replicate.Dairy goats in each group were fed with diets supplemented with 0(control group),20%,25%,30%and 35%Flammulina velutiper chaff,respectively.The pre-test lasted for 15 d and the formal test lasted for 60 d.The results showed that the average daily milk yield of dairy goats in 30%group was significantly higher than that in other groups(P＜0.05).The apparent digestibility of DM,CP,EE,NDF and ADF in 30%group was significantly higher than that in control group and 20%group(P＜0.05).Rumen pH value of dairy goats in 30%group was significantly lower than that in control group,20%group and 25%group(P＜0.05),but no significant difference was found between 30%group and 35%group(P＞0.05).Compared with control group,the ammonia nitrogen content of dairy goats in 20%group,25%group,30%group and 35%group was increased by 23.04%,37.40%,46.86%and 47.27%,respectively.The experiment indicates that adding 30%fermented Flammulina velutiper chaff in diet can improve the milk performance of Guanzhong dairy goats,promote the digestion and absorption of nutrients and increase the rumen fermentation status.
