摘要
母猪产程过长导致仔猪死产率高是母猪生产力低下的主要原因之一。论文讨论母猪产程和仔猪死产率的关系,分析现代母猪的基因型和饲养制度对母猪产程的影响。客观评价了缩宫素催产、诱发分娩、分娩母猪体力的补充、预防便泌、增加母猪的运动量等缩短产程的措施。指出改进饲养方式、增加母猪的运动量、改善母猪体质是缩短母猪产程从而降低死产率的根本出路。
High mortality of piglets resulted from the prolonged farrowing progress is the main cause of low reproductive capacity of sows.The relation between prolonged farrowing length and piglets mortality rate was dicussed.The effects of such factors as maternal genentic factor and housing system of the parturient sows on the duration of farrowing were illustrated in the paper.The measures to shorten parturition length including oxytocin injections,parturition inducement,prevention of astriction,physical force supplement,movement reinforce were evaluated objectively.It pointed out that it was a fundamental way to decreasing mortality through improving breeding fashion,enhance movement and meliorating constitution.
