摘要
越来越多的养猪场开始重视公猪信息素,在降低使用诱情公猪的生物安全风险和提高育种效率方面的作用。文章将通过回顾一系列的试验数据,包括不同性欲和年龄的公猪诱情效果上的差别,唾液腺手术后的公猪对母猪诱情的影响,以及不同的信息素产品在诱导母猪性行为以及体内激素水平的表达上的区别,来说明唾液类似物是公猪天然信息素的主要载体。不同的公猪的诱情效果差别,主要是源于唾液类似物中信息素的浓度以及分泌量的差别。通过分析雄烯酮对母猪性行为以及体内激素水平的影响,发现公猪分泌的信息素可能是多种分子的混合物,而不是单分子组成,不同性质的信息素将产生不同效应。
The role of boar pheromones in reducing the biosafety risk of using alluring boars and improving breeding efficiency has been valued by more and more pig establishments.This article will review through a series of experimental data,including differences that different sexual desires and ages on the boar seduction effects,the effects of boar surgery on sow seduction after salivary gland surgery,and the difference in pheromone products inducing sow sexual behavior and the expression of hormone levels in the body to illustrate the analogues of saliva is the main carrier of natural boar pheromone.The difference between different boars'inducement effect is mainly due to the difference in the concentration and secretion of pheromone in similar saliva.By analyzing androstenone on sow sexual behavior as well as the effects of hormone levels in the body,it was found that the pheromone secreted by the boar may be a mixture of molecules,rather than a single molecule,and pheromones of different properties will have different effects.
