摘　　要：试验选择了24头泌乳前中期的同一胎次、健康无病、具有相近体重、产奶量与泌乳期的荷斯坦奶牛,将其分为4组,每组6头牛,在奶牛日粮中添加苹果味果味剂、香蕉味果味剂、混合香型果味剂,并设置对照组(不添加果味剂)进行奶牛饲养试验。对奶牛的生产性能以及奶样中风味物质进行评定。试验结果表明:①在奶牛生产性能方面,与对照组相比,3种果味剂都有减缓产奶量下降的趋势,其中香蕉味的作用效果最好(产奶量下降:香蕉味0.5%,苹果味11.9%,混合味8.86%,对照13.5%)。②对奶样进行感官评价,在单独的色泽、组织状态、奶香味、果香味、甜味、酸味、苦味、涩味、饲草味和牛体味中,4种样品基本没有差异,4个样品的综合风味存在显著差异(P<0.05),在风味的总得分上,混合风味>苹果风味>香蕉风味=对照组。24 Holstein cows in premetaphase lactation stage with similar weight, lactation period, parities, milk, good health were selected and divided into 4 groups, each group had 6 cows. The trail was con- ducted to use apple flavor, banana flavor, mlxedfruit flavor to feed the cows, and the aim was to assess production performance of dairy cows and flavor components in milk samples. The result showed： （~ Compared with the control group, 3 fruity solvents all could slow the downward trend of milk production, especially the banana flavor group （Decreasing degree for milk production： the banana flavor is 0.5%, the apple flavor is 11.9%, the mixed fruit flavor is 8.86% and the control group is 13.5%. （~） Sensory evalu- ation to milk sample, 4 groups had no obvious differences at colour, structural state, creamy flavor, fruit flavor, sweetness, sourness, bitterness, astringency, forage taste and cowtail taste, but comprehensive fla- vor had obvious difference （P〈0.05）. In total points for flavor, mixed fruit flavor group 〉 apple flavor group 〉 banana flavor group = the control group.
