摘　　要：选用15头体质量、胎次、产奶量均相近中国荷斯坦奶牛,随机分为A、B、C三组(n=5):A组(对照组)饲喂基础日粮;B组(试验组1)饲喂基础日粮+50 g麦蓝菜种子;C组(试验组2)饲喂基础日粮+150 g麦蓝菜植株。试验周期24 d,每天测定各组奶牛产奶量及乳成分,研究麦蓝菜对奶牛产奶量及乳成分的影响。结果表明:B组较A组产奶量提高了15.56%(P<0.01),牛奶乳蛋白和干物质分别提高了11.9%和5.1%(P<0.01),乳脂率提高了9.4%(P<0.05),A、B两组间乳糖含量差异不显著;C组较A组产奶量提高了3.48%(P<0.01),牛奶乳蛋白和干物质体分别提高了6.3%和4.9%(P<0.01),乳脂率和乳糖分别提高了9.1%和6.6%(P<0.05)。研究表明,基础日粮中添加麦蓝菜植株和种子均可以显著提高奶牛产奶量和乳品质。Fifteen lactating Holstein cows were selected and divided into three groups randomly： control group （Group A, fed on the basal di-et）, experimental group Ⅰ（Group B, fed on the basal diet supplemented with 50 g seeds of Vaccaria segetalis （Neck）Garcke） and experimental group Ⅱ（Group C,fed on the basal diet supplemented with 150 g vegetable plants of Vaccaria segetalis （Neck）Garcke） .Milk yield and com-position in the three groups were determined simultaneously every day during the treatment phases of 24 days. The effects of Vaccaria segetalis （Neck）Garcke on milk yield and composition were studied.The results showed the milk yield in Group B was increased by 15.56% than Group A （P〈0.01）, milk protein and dry matter increased by 11.9% and 5.1%, （P〈0.01）, ration of milk fat increased by 9.4% （P〈0.05） ,re-spectively ,and no significant difference on the lactose content between two groups.The milk yield in Group C was increased by 3.48% （P〈 0.01） than group A ,milk protein and dry matter increased by 6.3% and 4.9% （P〈0.01） , ratio of milk fat and lactose increased by 9.1% and 6.6% （P〈0.05） ,respectively.The results indicated that the basal diet supplemented with vegetable plants and seeds of Vaccaria segetalis（Neck） Garcke can significantly increase milk production and quality.
