【摘要】 微多蛋白素饲喂产奶牛试验，通过对试验组和对照组在各阶段产奶量变化的比较及乳品质量指标的测定表明，微多蛋白素饲喂产奶牛具有明显的增奶效果，其奶质量亦得到改善，产奶牛日粮添加微多蛋白素 １００ｇ／头，可增奶 １．７９ｋｇ／头，替代豆饼组饲喂微多蛋白素 １００ｇ／·日，可增奶 ０．２７ｋｇ／头·日。更多还原

【Abstract】 In experiments of Mineproteinin feeding on lactating dairy cows, the milk yield changes and milk quality quota from experiment and control groups in each period were measured. The results showed that Mineproteinin could improve the milk yield remarkablly and better milk quality. When 100g Mineproteinin were added in the fodder for one lactating milk cow a day, 1. 79kg milk were produced extrally, while 100g Mineproteinin replaced SBC,0. 27kg milk were produced extrally.更多还原
