| 摘 要： | 本试验研究了犊牛日粮中添加酵母培养物对日粮营养成分消化率和体尺指标的影响，并对犊牛新型饲喂模式进行了有意义的探索。本试验结果表明，在日粮中添加酵母培养物和饲喂颗粒精料日粮，可以提高试验犊牛的消化率，促进其生长发育，缩短青年牛的培育周期，降低饲养成本，获得显著的经济效益。

| Abstract: | The Trial was conducted to study the effect of yeast culture additive on calves' daily gain, body measurement indexes, feed nutrient digestive coefficient,this experiment also explored a new feeding model effectively. The rusults showed that feeding calves by using yeast culture additive and pellet concentrate could improve calves' growing development, shorten the youthful dairy cows' breeding cycle and reduced the feeding cost. The economic benefit was very remarkable. |
