Effects of an anti‐gonadoliberin releasing hormone vaccine on testicular, epididymal and spermatogenic development in the horse [PDF]
Reproduction in Domestic Animals, Volume 57, Issue 8, Page 919-927, August 2022., 2022 Abstract The effects of the GnRH vaccine Improvac® on testicular and epididymal morphometrics, histology and spermatogenesis were measured in 19 young (15–20 months) colts randomly assigned to one control (saline, castration at 57 days, n = 6) or either of two GnRH vaccine‐treatment groups, T‐57 (castration at 57 days, n = 7) or T‐100 (castration at ...

Influences of Immunocastration on Endocrine Parameters, Growth Performance and Carcass Quality, as Well as on Boar Taint and Penile Injuries [PDF]
Animals, 2020 Castration of male pigs without anesthesia is a significant welfare issue. Improvac®, a GnRH vaccine induces an endogenous immune response leading to a decrease in testicular steroids.

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
