摘　　要：[Objective] To study the effects of apple pomace on milk performance of dairy cows. ~Method] A total of 48 Holstein dairy cows at the same parity and with close lactation stage and similar daily milk yield were randomly assigned to six groups. The supplementary feed was composed of apple pomace, alfalfa meal, com and premix, and it was processed into pellets. In the groups I - V, the percentage of apple pomace was 17.5%, 35.0%, 52.5%, 70.0% and 0%, respectively. Each cow was fed with supplementary feed （3 kg/d）. [ Result] The milk yield in the group II and group V was increased significantly （ P 〈 0.05）, and the fat content in milk of the group III and V was significantly higher than that of the con- trol group （P 〈 0.05）. [ Conclusion] The supplementary apple pomace can improve the milk performance of dairy cows effectively.[Objective] To study the effects of apple pomace on milk performance of dairy cows. ~Method] A total of 48 Holstein dairy cows at the same parity and with close lactation stage and similar daily milk yield were randomly assigned to six groups.
