摘　　要：在高产奶牛目粮中添加13克高活性康贝试验组的产奶量比对照组提高1.78千克(P<0.05),当添加量达到20克时,增幅达2.74千克(P<0.05),乳脂量也显著比对照组高9.88%(P <0.05),而且牛奶中的体细胞数也显著低于13克组和对照组(P<0.05)。大群饲喂20克康贝的生产试验也获得了相似的结果。Compared with the control group,supple- mentation with 13g COMBO in the ration of high yielding dairy cows significantly increased average daily milk yield by 1.78kg(P<0.05),and continu- ously went up by 2.74kg(P<0.05)with the grow- ing supplementation of 20g.Milk fat yield was high- er than that of control group when 20g COMBO was fed,while the somatic cell count (SCC) in the milk was markedly lower than those of control and 13g fed groups.Similar results were obtained through the 20g fed trials in some larger commercial dairy herds.
