Effects of immunization against GnRH on gonadotropins, the GH-IGF-I-axis and metabolic parameters in barrows

Animal, 2008
Surgically castrated male piglets (barrows) reveal an increase in LH and a decrease in GH compared to untreated boars. Boars that were castrated by immunization against gonadotropin releasing hormone (GnRH) have decreased LH but maintain GH.

Field experience with surgical castration with anaesthesia, analgesia, immunocastration and production of entire male pigs: performance, carcass traits and boar taint prevalence

Animal, 2015
Male piglets are castrated to reduce boar taint and also to reduce aggressive and sexual behaviour. However, the procedure as traditionally performed is painful and negatively affects performance.
