按产奶量、胎次、泌乳天数相近的原则选取110头泌乳奶牛，采用配对分组设计分为试验组与对照组。对照组饲喂基础日粮，试验组在日粮中添加2kg的菠萝渣替代等量玉米秸秆青贮。试验结果表明，试验组平均奶产量较对照组高出0.6kg/（头·d）；牛奶乳脂率、乳蛋白率没有明显差异。

In this experiment, a total of 110 cows with the similar milk production, lactation and days in milk were randomly divided into trial group and control group. Experimental group cows were added 2 kg/day of pineapple slag in the diet to replace the diet of corn stover silage, control group cows were fed with basic diet. The results showedthattheaveragemilkyieldforexperimentalgroupwasincreasedby0.6kg/day.Therewasnosigniifcantdifference in milk fat percentage and milk protein percentage.
