Immunocontraception of male and female giraffes using the GnRH vaccine Improvac®. [PDF]
Zoo Biol, 2022 I Protocols for contraception using the GnRH vaccine Improvac® were developed. A clear reduction of fecal hormone metabolites in female giraffes was achieved with three, and in males with four or five injections at 4‐week intervals. Effective booster injections were administered at 2‐month intervals in the first, and at three to 4‐month intervals in ...

Effects of an anti-gonadoliberin releasing hormone vaccine on testicular, epididymal and spermatogenic development in the horse. [PDF]
Reprod Domest Anim, 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 ...

Immunocastration in adult boars as a model for late-onset hypogonadism. [PDF]
Andrology, 2022 Abstract Background While immunocastration has been studied in male pre‐pubertal pigs, data on older, sexually mature animals are limited. To understand the physiological effects of androgen deprivation in the late sexual development phase, we compared mature immunocastrated boars (n = 19; average age = 480 days) to young male immunocastrated pigs (n =

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 5, Page 1158-1166, September 2023., 2023 Abstract In cervids, blood biochemical markers may reflect changes in various physiological and environmental factors, especially in response to changes in metabolism following nutrient supplementation or the manipulation of hormone production. Decreasing androgen production through immunocastration (IC) to ease the husbandry of male animals is ...

Suppression of reproductive behaviour and gonadal function in female horses—An update
Reproduction in Domestic Animals, Volume 57, Issue S4, Page 4-12, September 2022., 2022 Abstract The behaviour of mares is often detrimental to their performance resulting in frequent demand for methods to suppress gonadal function. In addition, prevention of unintended reproduction especially in feral horse populations may require methods for suppression of gonadal function.

Active immunisation against GnRH as treatment for unilateral granulosa theca cell tumour in mares
Equine Veterinary Journal, Volume 53, Issue 4, Page 740-745, July 2021., 2021 Abstract Background Stallion‐like or aggressive behaviour in mares affected by unilateral granulosa theca cell tumour (GTCT) is well‐known, but use of a GnRH‐vaccine as an alternative to surgical removal of the neoplastic ovary has not been investigated.

Immunocastration and its effects on carcass and meat traits of male pigs
Semina: Ciências Agrárias, 2018 To compose the experiment, 160 male Topgen pigs - 80 surgically castrated (treatment 1) and 80 immunocastrated (treatment 2) - were randomly selected from a commercial swine farm at the moment of slaughter.
