| 摘 要： | 试验旨在研究叶黄素对牛乳叶黄素沉积与理化指标的影响。试验选择胎次、泌乳天数、产奶性能和体细胞数相近奶牛60头，随机分为5组，分别为对照组、处理Ⅰ组、处理Ⅱ组、处理Ⅲ组和处理Ⅳ组，每组12头。对处理组奶牛每天分别饲喂叶黄素50 g（A试验料）、100 g（A试验料）、100 g（B试验料）、150 g（A试验料）。其中在0、10、20、30、40和50 d检测牛奶中叶黄素、乳脂肪、乳蛋白质、乳糖和干物质含量及泌乳量的变化情况。结果表明，在本试验条件下，日粮中添加叶黄素样品A优于样品B。添加150 g/（d·头）（以日采食10 kg精料计）样品A可显著提高奶中叶黄素的含量。建议生产中日粮叶黄素添加量选用150 g/（d·头）为宜。

| Abstract: | This experiment was conducted to investigate the effects of the lutein on bovine milk physical and chemistry index of diet.Sixty Holstein cows were randomly divided into five treatment groups: The control group, the treatment group Ⅰ,the treatment group Ⅱ, the treatment group Ⅲ and the treatment group Ⅳ.The treatment group cows were fed daily lutein 50 g (A experiment material), 100 g (A experiment material), 100 g (B experiment material), 150 g (A experiment material). The lutein, milk fat, milk protein, lactose, dry matter content and milk yield changes in milk were measured in which 0, 10, 20, 30, 40 and 50 d. The results showed that the sample A was better than sample B of lutein the diet.Adding 150 g sample A to every cow and every day could significantly improve the content of lutein in milk.Recommended dietary lutein content in the production of the 150 g/d was appropriate. |
