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

Immunocastration and testosterone supplementation alter testicular development and muscle collagen gene expression in male chickens [PDF]
Poultry ScienceImmunocastration using a gonadotropin-releasing hormone (GnRH) vaccine offers a potential alternative to surgical castration in poultry, yet its effects on growth performance and meat quality in chickens remain poorly characterized.

Evaluación de la eficacia de inmunocastración (Improvac) en machos porcinos y su impacto en la calidad de la carne [PDF]
, 2011 La castración quirúrgica de los lechones es un procedimiento de manejo que ha sido practicado por siglos en granjas de todo el mundo. Los cerdos machos se castran para reducir su comportamiento agresivo, facilitar el manejo y prevención del olor a verraco, un sabor/olor desagradable, distintivo que puede ser percibido durante la preparación o la ...

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence. [PDF]
AndrologyABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

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 ...

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 ...
