Immunocastration of colts and immunospeying of fillies

Immunology & Cell Biology, 1993
SummaryA 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 ...

Lysine requirement for growing-finishing immunocastrated male pigs

Tropical Animal Health and Production, 2015
Eighty 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 ...

Immunocastration with gene vaccine (KISS1) induces a cell-mediated immune response in ram testis: A transcriptome evaluation.

Reproduction in domestic animals = Zuchthygiene, 2022
Immunocastration vaccines achieve their effects through neutralization of the endogenous hormone by the humoral antibody produced against the immunized genes. But there is little information regarding cell-mediated immune response on the gonadal function

Immunocastration of goats using anti-gonadotrophin releasing hormone vaccine

Theriogenology, 2018
The aim of this study was to evaluate the immuno-sterilizing action of anti-gonadotrophin-releasing hormone (anti-GnRH) vaccine in goats. Eighteen male goats were randomly distributed to receive three treatments: T1 (control) - whole animals, and T2 and T3 - application of 0.5 and 1.0 mL of anti-GnRH vaccine, respectively, with six replicates and one ...

Sustainability in pork production with immunocastration

2021
The ERA-NET project SuSI deals with immunocastration (IC) as a sustainable alternative to pork production with surgical castrates and boars with the aim to optimize pork production on a social, environmental and economic level. Most male piglets in the EU are surgically castrated, which is painful and violates their physical integrity.

Immunocastration in Bísaro Pig

2022
O porco Bísaro (BP), raça autóctone reconhecida pelos seus produtos de fumeiro de elevado valor, desempenha um papel importante na economia local. Os animais desta raça são abatidos em idades mais avançadas, normalmente acima do ano de idade, e com pesos vivos mais elevados, comparativamente aos dos sistemas industriais.

Protein requirements in finishing immunocastrated male pigs

2019
Immunocastration is a method for raising male pigs without surgical castration and with reduced boar taint. It consists in two vaccinations against GnRH. After the second vaccination (V2) performed a few weeks before slaughter, pigs increase their feed intake whereas protein deposition remains constant.

Metabolizable and net energy requirements for entire and immunocastrated male pigs and digestible lysine for immunocastrated males

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%
