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 ...

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%

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.

Immunocastred Pigs: from fattening to slaughter

Boar taint is defined through the unpleasant smell and taste of the meat or meat products of male noncastrated pigs, that becomes evident after being cooked. In order to solve this problem, immunocastration appears as an alternative to the traditional methods of castration, which present some disadvantages, namely concerning animal welfare. Despite the
