Animal Reproduction Science, 2011 Gonadotropin-releasing hormone (GnRH) vaccine (Improvac(®)) is effective at diminishing boar taint by interfering with testis function. Early pre-pubertal vaccination at 10 and 14 weeks-of-age could be desirable if sufficient and sustained effects could be achieved.

Effect of vaccination against gonadotrophin-releasing hormone, using Improvac®, on growth performance, body composition, behaviour and acute phase proteins [PDF]
Livestock Science, 2010 The objective of this study was to evaluate the effect of vaccination against GnRH on performance traits, pig behaviour and acute phase proteins. A total of 120 pigs (36 non-castrated males, NCM; 36 males to be vaccinated, IM; 24 castratedmales, CM; and 24 females, FE)were controlled in groups of 12 in pens with feeding stations allowing the recording ...

Two complementary methods to control gonadotropin‐releasing hormone vaccination (Improvac®) misuse in horseracing: Enzyme‐linked immunosorbent assay test in plasma and steroidomics in urine [PDF]
Drug Testing and Analysis, 2017 Since the availability on the European market of the vaccine Improvac® dedicated to male pig immunological castration, the risk of misuse of this product in horses is now considered as a threat for the horseracing industry. Immunological castration is not allowed by the racing codes (immune system, Article 6).

Histological and Morphometric Examination of the Testes of Boars and Male Pigs Immunocastrated with Improvac® [PDF]
Acta Scientiae Veterinariae, 2017 Background: Surgical castration of male piglets is frequently performed to prevent development of an unpleasant taste and flavor in meat of mature males, called boar taint. Disadvantages of this method are primarily related to the lower feed efficiency of surgically castrated male pigs, production of less lean meat and more fat on the carcasses than ...

The effectiveness of Imrovac® in industrial pork production
Theoretical and Applied Veterinary Medicine, 2021 The clinical efficacy of the use of immunobiological castration was studied in comparison with boars in which orchidectomy was performed by open method «on a ligature», as well as in non-castrated animals.

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 ...

Immunocastration in adult boars as a model for late‐onset hypogonadism
Andrology, Volume 10, Issue 6, Page 1217-1232, September 2022., 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 =

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.
