Immunocastration

Revista Colombiana de Ciencias Pecuarias, 2011
Immunocastration (IC) of pigs during their finishing phase avoids the traumatic castration surgery (Q) still practiced in many countries to prevent boar taint in pork. We have not found reports on IC evaluated on culled adult boars. In this study we evaluated boar taint, spermatogenesis, and weight loss of adult boars after castration by IC versus Q. A

Effects of immunocastration and supplementary feeding level on the performance and blood biochemical markers of farmed yearling fallow deer (Dama dama)

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.

Effects of an anti‐gonadoliberin releasing hormone vaccine on testicular, epididymal and spermatogenic development in the horse

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 ...

Welfare of pigs on farm

EFSA Journal, Volume 20, Issue 8, August 2022., 2022
Abstract This scientific opinion focuses on the welfare of pigs on farm, and is based on literature and expert opinion. All pig categories were assessed: gilts and dry sows, farrowing and lactating sows, suckling piglets, weaners, rearing pigs and boars. The most relevant husbandry systems used in Europe are described.
