Male Reproductive Organ Weight: Criteria for Detection of Androstenone-Positive Carcasses in Immunocastrated and Entire Male Pigs [PDF]
Animals, 2023 Immunocastration and rearing of entire males (EMs) are sustainable alternatives to surgical castration. However, these animal carcasses have variable risk of boar taint and should be identified at the slaughter line.

Effects of Dietary Bromide, Magnesium and Tryptophan and Immunocastration on Growth Performance and Behaviour of Entire Male Pigs [PDF]
AnimalsThe growth of boars may be inhibited because of aggressive and/or sexual activity. Dietary Br, Mg and tryptophan (Trp) as well as immunocastration may reduce these behaviours. In Experiment 1, 200 boars and 40 barrows were allocated to six groups of four

TEORETICAL AND PRACTICAL ASPECTS OF IMMUNOCASTRATION [PDF]
Stočarstvo : Časopis za unapređenje stočarstva, 2014 Due to animal welfare problems and strong public opposition a ban on surgical castration of male piglets is foreseen in EU until the end of 2018. To cope with this major change in pig production, intensive research of possible alternatives is carried out,
