摘要
当前以源自北欧的不耐热品种荷斯坦牛作为我国主要的奶用品种遍布全国各地,随着其生产性能的不断提高其热应激的表现也越来越严重。特别是在南方农区热应激造成的经济损失十分明显。因此,研究采取有效的预防措施,消除热应激对奶牛的影响,对保证奶牛高产稳产具有重要的经济意义。
Most area has the main cow breed of Hesitan which comes from Northern Europe and not bear to heat. With increasing production capabilities, the performance of heat stress is more and more serious.
