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 ...

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 =
