| 摘 要： | 目的]通过饲喂试验,探究日粮中添加赛乐锌对奶牛生化指标和生产性能的影响。方法]将试验奶牛随机分为4个处理,每个处理2个重复,采用4×4拉丁方设计,进行饲喂试验。结果]表明,在奶牛日粮中添加350mg/kg的赛乐锌,奶牛血清锌浓度和血清碱性磷酸酶(AKP)活性显著提高(P0.05);各试验组血清尿素氮浓度呈下降趋势,但差异不显著(P0.05)。结论]在不影响乳脂率和乳蛋白率的前提下,显著提高奶牛的产奶量,牛奶中乳锌的含量显著提高,使牛乳的品质得到很大程度的提升。 |

| Abstract: | Objective]Zinc is one of the most essential microelements in dairy cattle,with great physio logical and pharmacological functions, and zinc is an essential element in diet of dairy cattle. Method] 8 dairy cattle with the similar output of milk were chosen as test cattle. The cattle were randomly classified into 4 groups, each group with two repeats, designed control group and the remains were used as treatment as 4 N 4 Latin Square design. One was used as the groups which were added amino acids chelating zinc at 200 mg/kg, 350 mg/kg, 500 mg/kg of diet of dairy cattle. After one month, we measure output of milk and kinds of biochemical index of our test cattle. Result]The result showed that adding amino acids chela ting zinc at 350 mg/kg of diet of dairy cattle could significantly increase serum Zn and alkaline phosphates （AKP） activity（P〈0.05）. BUN tended to be lower in supplemental Zinc Amino Acid Chelae treatments, but no significant difference（P〉0.05）. Conclusion]Adding amino acids chelating zinc could improve milk yield and quality without influencing fat percentage and protein rate. |
