为探究不同饲养方式对泌乳驴产奶量和乳营养成分的影响,选择14 头泌乳量相近的带驹母驴,随机分成全舍饲组和放牧+补饲组,每组7 头泌乳驴,试验期29 天,采集5 次乳样进行不同营养成分测定。结果显示,与全舍饲相比,放牧+补饲饲养方式下驴乳中的非全乳固体、蛋白质、灰分、亚油酸C18∶2、亚油酸C 18∶3、棕榈酸C 16∶0、丙氨酸、甘氨酸、亮氨酸、酪氨酸含量分别提高了9.64%、55.15%、22.86%、9.7%、4.58%、6.06%、5.56%、13.64%、8.62%和9.43%（P<0.05）,脂肪、乳糖、硬脂酸C18:0含量分别下降了37.10%、6.00%、12.26%（P<0.05）,泌乳驴日平均产乳量提高了12.06%（P<0.05）,而驴乳中所含的水分与全乳固体差异不显著（P>0.05）,母驴日养殖成本可降低3~4 元/头。结论放牧+补饲饲养方式既可提高乳品质,也可节约养殖成本。
To explore the effects of different rearing patterns on milk yield and nutrient composition of lactating donkeys. Fourteen female donkeys with foals with similar milk production were randomly divided into two groups：the whole house feeding group and the grazing + Supplement feeding group. Compared with whole house feeding,the contents of solid,protein,ash,linoleic acid C 18∶2,linoleic acid c 18∶3,palmitic acid c 16∶0,alanine,glycine,leucine,tyrosine in donkey milk increased significantly by 9.64%,55.15%,22.86%,9.7%,4.58%,6.06%,5.56%,13.64%,8.62% and 9.43%,respectively（P<0.05）,the contents of fat,lactose and stearic acid c 18∶0 decreased by 37.10%,6.00% and 12.26%,respectively（P<0.05）,the average daily milk yield of lactating donkeys increased by 12.06%（P<0.05）,but the moisture content of donkey milk was not significantly different from that of whole milk（P>0.05）,the daily breeding cost of female donkey can be reduced by 3 ~ 4 yuan / head.Conclusion：the method of grazing and supplementary feeding can not only improve the quality of milk,but also save the cost of breeding.
