Abstract:

Traditional surgical castration technology is being challenged by animal welfare and large-scale standardized livestock production.As an alternative to surgical castration,immuno-castration can block testicular development,control sexual behavior,and avoid the pain caused by surgery.Immuno-castration uses immunological methods to destroy the hormone balance of the hypothalamic-pituitary-gonadal axis,decrease the hormone levels of GnRH,LH,FSH,and gonadal hormone,inhibit the gonadal function,and then achieve the purpose of castration.Immuno-castration includes hormone immuno-castration and gene immuno-castration,and its targets have undergone bottom-up screening on the hypothalamic-pituitary-gonadal axis,which identified are testosterone,LH,FSH,GnRH and KISS-1.The three targets of GnRH hormone,GnRH and KISS-1 genes located upstream on the hypothalamic-pituitary-gonadal axis have better castration effects.Studies on the effect and mechanism of immuno-castration show that immuno-castration has the characteristics of improving production performance,safety and reversibility.While the reversible mechanism of immuno-castration is still unclear.Castration causes the adrenal gland to play a compensatory role,and the effect of immuno-castration on adrenal compensation has not been reported.This paper introduces the immuno-castration mechanism of targets,discusses the characteristics and application of immuno-castration,in order to provide theoretical basis for promoting the application of immuno-castration technology in the field of animal production and reproduction.
