Early Immunocastration of Pigs: From Farming to Meat Quality [PDF]
Animals, 2021 The study aimed to test a very early immunization of pigs to prevent boar taint with regard to its practicability and influence on production performance, its reliability in ensuring good meat and fat quality, and animal welfare. Immunization was already conducted at piglet production stage and could be easily integrated into routine vaccination (week ...

Welfare Aspects of Raising Entire Male Pigs and Immunocastrates [PDF]
Animals, 2020 For a long time, scientists assumed that newborns have a severely limited sense of pain (if any). However, this assumption is wrong and led to a “start of the exit” from piglet surgical castration. Some of the currently discussed or already implemented alternatives such as general or local anaesthesia during surgical castration raise additional welfare

Journal of Animal Breeding and Genetics, Volume 137, Issue 6, Page 545-558, November 2020., 2020 Abstract Pig production contributes to environmental pollution through excretion of phosphorus and nitrogenous compounds. European pig production requires annual imports of currently 36 million tons of soya bean, because domestic plant protein sources often do not meet the required protein quality.

Immunocastration of Male Pigs – Situation Today
Procedia Food Science, 2015 AbstractImmunological castration of male pigs is an attractive alternative to surgical castration and nowadays is increasingly used in many countries to reduce boar taint and improve pork quality. Moreover, immunocastrated pigs showed reduced sexual and aggressive behaviour compared to entire male pigs, thus improving animal welfare.

Testicular morphometry as a tool to evaluate the efficiency of immunocastration in lambs
Animal Reproduction, 2022 This study aimed to evaluate the efficiency of immunocastration in lambs using testicular morphometry. Thirty lambs were randomly divided into two treatments (subcutaneous administration of 1.0 mL and 0.5 mL of an anti-GnRH vaccine) and a control group (1.0 mL saline solution).

Immunocontraceptives: New Approaches to Fertility Control
BioMed Research International, Volume 2014, Issue 1, 2014., 2014 The rapidly increasing global population has bowed the attention of family planning and associated reproductive health programmes in the direction of providing a safe and reliable method which can be used to limit family size. The world population is estimated to exceed a phenomenal 10 billion by the year 2050 A.D., thus presenting a real jeopardy of ...

The effect of immunocastration on adipose tissue deposition and composition in pigs
animal, 2021 Immunocastrated pigs (IC) exhibit intensive fat deposition after immunisation, but the underlying mechanisms of intensified fat metabolism and deposition are not yet fully understood. Moreover, there is also a lack of comparative studies performed on IC, entire males (EM) and surgical castrates (SC).

Journal of Vaccines, Volume 2013, Issue 1, 2013., 2013 We have investigated the effect of immunization against gonadotropin releasing hormone (GnRH) using a commercial canine GnRH vaccine on testosterone concentration, testicular volume, testicular histology, and intermale behavior in intact male llamas and alpacas.

Considerations on the performance of immunocastrated male pigs
Animal, 2011 With the ongoing social pressure on surgical castration of pigs, an increase in the population of pigs that are either not castrated or immunocastrated (IC) can be expected. In both cases, their nutrient requirements and performance will differ from surgically castrated pigs and will require changes in their management. Immunocastration is performed by

EFSA Journal, Volume 23, Issue 7, July 2025.Abstract This Scientific Opinion provides an assessment of beef cattle welfare focusing on risks related to flooring, water access, nutrition and feeding, high environmental temperatures, lack of environmental enrichment, lack of outdoor access, minimum space allowance and mixing practices. In addition, risks related to pasture and feedlots, weaning of
