中文摘要：以3头年龄相同、平均体重为(650±20)kg、同处泌乳中后期平均泌乳量为15 kg左右、装有永久性瘤胃瘘管的荷斯坦奶牛为试验动物,试验采用3×3拉丁方设计,研究探讨向日粮中添加不同的油料籽实(日粮脂肪含量均在6.5%)对奶牛瘤胃代谢及生产性能的影响,为向日粮中添加油料籽实提高乳脂中共轭亚油酸含量的研究提供基础数据。3种籽实分别为葵花籽、亚麻籽、菜籽。研究结果表明,日粮中添加不同的油料籽实对奶牛瘤胃液纤毛虫数量动态变化、pH值动态变化、NH_3-N浓度动态变化以及对菌体蛋白浓度的影响差异不显著(P>0.05),对奶牛泌乳量及乳成分的影响差异不显著(P>0.05),并均有改善乳质的作用。

外文摘要：Three healthy Chinese Holstein lactating dairy cows of same age and at same lactation period were used as experiment animals. They were all installed with permanent fistula on rumen, and have an average body weight of 650 ± 20 kg. An experiment of 3 × 3 Latin square design was carried out to study the effect of adding different oilseeds at a same diet fat level of 6.5 % on cow metabohsm and production performance. The aim of this work is to provide foundation data for enhancing the conjugate linoleic acid content of butterfat by adding oilseeds into diet. Three kinds of oilseeds are tested： sunflower seeds, flax seeds and colza seeds. Results show no significant difference （ P 〉 0.05） for the effects of adding different oilseeds on rumen protozoa numbers, rtunen ph value, NH3 - N concentration, bacterial protein concentration, lactating quantity, and milk composition （ P 〉 0.05） ; while the additions of different oilseeds all improve the milk quality.
