Mechanistic insight into the role of immunocastration on eliminating skatole in boars
Theriogenology, 2019The accumulation of skatole in fat tissue is one of the predominant factors, causing boar taint. The present study was aimed to understand the mechanism whereby active immunization against GnRH (immunocastration) eliminates skatole in boars. Thirty-six boars were assigned within litter into three groups (n = 12): control, surgically castrated, or ...

Immunocastration of colts and immunospeying of fillies
Immunology & Cell Biology, 1993SummaryA series of experiments using an ovalbumin conjugated gonadotrophin releasing hormone was used to stimulate antibody production, suppress testosterone secretion and depress testicular function in yearling and 2 year old colts and fillies. In the preliminary experiment, an injectable oil–based formulation was administered to yearling colts ...

Immunocastration in cattle and pigs
Livestock Production Science, 1995Abstract Raising gonad-intact farm animals has many advantages over conventional castrates. Intact animals are generally more efficient in the conversion of feed into lean meat. In addition to decreasing production costs, better feed efficiency also leads to a reduction in the output of various biological pollutants, particularly nitrogen.

Immunocastration and immunospaying in horses
2022This study has concentrated on the effects of an ovalbumin conjugated GnRH vaccine on the testicular function of colts, vaccinated at various ages from pre-pubertal to 3-yr old using three forms of the vaccine: mineral oil-based, water-based and subcutaneous implant.

Seit Jahrhunderten werden in Europa männliche Ferkel chirurgisch kastriert, um Ebergeruch und eberspezifisches Aggression- und Sexualverhalten zu vermeiden. Die chirurgische Kastration von Eberferkeln erfolgt dabei meistens ohne Anästhesie oder Analgesie und darf so in der Europäischen Union innerhalb der ersten Lebenswoche durchgeführt werden.

Lysine requirement for growing-finishing immunocastrated male pigs
Tropical Animal Health and Production, 2015Eighty boars (19.3 ± 2.49 kg) were vaccinated twice (100 and 128 days of age) against gonadotropin releasing hormone (Vivax™ vaccine), for a randomised block design study aiming to evaluate five digestible lysine (DLys) level treatments, with three phase-feeding per treatments (9-8-7; 10-9-8; 11-10-9; 12-11-10 and 13-12-11 g/kg) during the growing ...

In the first chapter, the objective was to determine the metabolizable and net energy requirements for maintenance and production of entire males and immunocastrated males from 70 to 130 kg of body weight, using the factorial method. Sixty entire male pigs were randomly assigned to a performance trial with four treatments (ad libitum, 75%, 50%, and 25%

Pork production with immunocastration: welfare and environment
2018Societal pressure to end surgical castration of piglets without anaesthesia and pain relief is increasing. Twoalternatives to surgical castration currently exist: raising entire males (EM) or immunocastrated males (IC), bothwith advantages and disadvantages. Considering animal integrity, EM may be the preferred choice.
