Reproductive and Behavioral Evaluation of a New Immunocastration Dog Vaccine [PDF]
Animals, 2020 Canine immunocastration development has been of interest for many years as a complementary strategy to surgical castration. The purpose of this paper was to verify the effect of a recombinant vaccine for dog immunocastration. Two tests were done, one under controlled conditions and a second under field conditions. Animals were injected with 1 mL of 500

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.

Multiple-Pathway Synergy Alters Steroidogenesis and Spermatogenesis in Response to an Immunocastration Vaccine in Goat [PDF]
Cells, 2023 Background: Animal reproduction performance is crucial in husbandry. Immunocastrated animals serve as an ideal animal model for studying testicular function. During androgen suppression, the testis undergoes dramatic developmental and structural changes,

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

Welfare Aspects of Raising Entire Male Pigs and Immunocastrates [PDF]
Animals, 2020 For a long time, scientists assumed that newborns have a severely limited sense of pain (if any). However, this assumption is wrong and led to a “start of the exit” from piglet surgical castration.

TEORETICAL AND PRACTICAL ASPECTS OF IMMUNOCASTRATION
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, in particular fattening of entire (EM) and immunocastrated (IC) males.
