牛乳铁蛋白活性肽对奶牛隐性乳房炎的防治作用及对其生产性能的影响

摘要

The experiment aimed to study the effect of LFA-LFC on the control of subclinical mastitis in dairy cows. At the same time, milk yield and milk quality were also assessed. The test consisted of three groups, group A (control group): basal diet, group B (experimental group): based diet + 600g/t LFA-LFC, group C (experimental group): basal diet + 1200g/t LFA-LFC. In conclusion, LFA-LFC could not only significantly (P<0.05) decrease the somatic cell counts and increase milk yield, but also increase the percentage of milk fat and milk protein.%本试验旨在研究牛乳铁蛋白活性肽对奶牛隐性乳房炎的防治作用,以及对产奶量、乳品质的影响.试验共设3组,分别为:(1)对照A组:基础日粮;(2)试验B组:基础日粮+牛乳铁蛋白活性肽(600g/t精补料);(3)试验C组:基础日粮+牛乳铁蛋白活性肽(1200g/t精补料).研究发现,日粮中添加牛乳铁蛋白活性肽不仅可以显著(P<0.05)降低乳中体细胞数、提高产奶量,还可提高乳脂率和乳蛋白水平,改善乳品质.
