摘要
哺乳仔猪死亡率较高是困扰养猪生产的主要问题之一,了解其原因对于提高动物福利、降低生产损失和提高养殖效益都具有重要指导意义。哺乳仔猪非疫病死亡原因主要是压死、冷应激和饥饿。从仔猪、母猪和环境等方面分析造成哺乳仔猪死亡的影响因素,以期对加强开展仔猪初乳摄入、环境温度控制、母猪营养调控、围栏饲养模式、分娩管理、仔猪寄养和代乳母猪等方面技术研究和应用,为降低哺乳仔猪死亡率和提高生猪养殖经济效益提供一定的理论依据。
High piglet pre-weaning mortality(PWM) is one of the main reproductive elements that affects animal productivity in the swine industry.Cognition of factors that influence piglet PWM are important to enhance animal welfare,to decrease production loss and to improve profits in commercial farms.The main reasons leading to PWM are chilling,starving,or being crushed by the sow.The most important non-infectious causes of piglet PWM are usually classified into three major groups:piglet,sow,and environmental factors.Scientific research on colostrums intake,ambient temperature control,sow nutrition provision,housing system,partum management,cross-fostering,nurse sow system is of great interest.The main objective of the present work was to review the most important non-infectious causes of piglet PWM and to provide the theory instruction for increasing economic efficiency of pig breeding.
