摘要: 过去二十多年,随着奶牛群体遗传改良计划的持续推进和养殖技术的不断进步,中国奶牛集约化养殖水平和产奶量正在不断提高。但是,历年来的繁育数据显示,越是高产的牛群,繁殖性能下降的趋势越明显,繁殖问题越突出,高产引发的繁殖力下降已经成为制约中国乃至全球奶业发展的瓶颈。低繁殖力会严重影响奶牛生产群的更新速度以及优质牛群泌乳性能的正常发挥。奶牛养殖生产中,造成高产奶牛繁殖性能降低的因素众多,包括遗传因素、环境因素和疾病因素等。近年来,疾病因素对奶牛繁殖性能的影响越来越突出。根据疾病的发生部位,可将影响高产奶牛的疾病分为生殖器官疾病和非生殖器官疾病。作者详细介绍了近年来国内外不同疾病对奶牛繁殖性能影响的相关研究资料,重点分析了疾病通过神经系统、生殖内分泌系统和体液免疫系统等多个途径影响奶牛繁殖性能的分子机制,并对疾病与高产奶牛繁殖性能今后研究的方向提出了展望和思考,以期为提高中国高产奶牛群繁殖效率和经济效益提供一定的借鉴和理论依据。
