Abstract

The objective of this study was to determine the effects of fermented distillers' grains supplemented in diets on performance, apparent nutrient digestibility, ruminal fermentation and serum biochemical indices in house-fed yaks. A complete randomized design was adopted in this study, and twenty 3-year-old Maiwa male yaks weighted (208.30±3.31) kg were randomly divided into 2 (A and B) groups with 10 replicates of 1 yak in each group. Yaks in A group were fed corn-soybean diet, and yaks in B group were fed the corn-fermented distillers' grains diet which contain 9.25% fermented distillers' grains and equal nitrogen content compared with the diet of A group. The experiment lasted for 60 d. The results showed as follows: compared with A group, 1) dry matter intake and daily gain in B group were significantly increased (P0.05); 4) serum total protein and high-density lipoprotein contents in group B were significantly increased (P0.05). Consequently, the diet that contain 9.25% fermented distillers' grains can improve performance and nutrients digestibility in yaks, but does not change the type of rumen fermentation, and has no adverse effects on serum biochemical indices.
