信息素在调控母猪夏季不孕症中的应用

Pheromone improves sow infertility in summer

每年的夏季和初秋,公猪的性欲和睾酮、雄烯酮水平都较低,唾液中排出的信息素在高温环境中较易挥发失效,这对于诱导母猪性行为以及卵泡发育会产生不利影响。采用三分子公猪信息素产品Boar Better~?配合公猪在夏季进行诱情查情,通过对2 000头母猪的试验,证明Boar Better~?+公猪能有助于改善夏季母猪的繁殖成绩,使配种率提高6%,分娩成功率提高12%,每窝增加0.54头活仔数,每窝降低0.3头死胎数,每批次多产25%的仔猪。

In summer and early autumn months,boars have low levels of libido and testosterone and androstenone.The pheromone excreted from saliva is more volatile and fails in the high temperature environment,which will have an adverse eff ect on the induction of sow sexual behavior and follicular development.Using three-molecule boar pheromones(BoarBetter®)to cooperate with boars to conduct sensation check in summer,through the test of 2000 sows,it is proved that BoarBetter®+boar can help improve the breeding performance and breeding rate of summer sows increase by 6%,delivery success rate by 12%,increase the number of live births per litter by 0.54,reduce the number of stillbirths by 0.3 per litter,and produce 25%more pigs per batch.
