利用“青贮宝”青发酵剂贮的玉米饲喂奶牛，研究其对奶牛产奶量的影响。试验选取20头中国黑白花奶牛，分为试验组和对照组，试验组饲喂青贮宝青贮玉米，对照组饲喂普通青贮玉米。结果表明：试验组每头牛的日产奶量可提高1．14～1．21kg。
The experiment was conducted to investigate the effect of silage corn treated by Qingchubao on cow milk yield. Twenty Holsteins were selected and divided into two groups,experimental group fed silage corn treated by Qingchubao,control group fed common silage corn. The results showed that daily milk yield of experimental group improved 1. 14-1.21 kg per cow,daily income increased 3.01 Yuan per cow.
