In this study, the performance of male pigs immunized against GnRH was determined in relation to the onset of their biological response to the immunization. Pigs were immunized at 9 and 17 wk of age and were housed in a pen together with both a surgi

We have investigated, under the normal conditions of local Chinese pig farming, castration of young male pigs by vaccination with a newly developed vaccine against gonadotrophin releasing hormone (GnRH). Because of the very early onset of puberty, lo

There are few male contraceptive methods, and research is required to broaden the scope of available male antifertility methods. Two approaches toward hormonal contraception are currently being investigated. The first relies on elimination of testost

Immunization against GnRH-like peptides to immunocastrate boars can be very effective in preventing boar taint and in reducing testis weight (TW) and size (TS). Experiments using vaccines with different efficacies resulted in a total of 203 male pigs

The aim of the present work was to define an FSH receptor (FSHR) peptide that can induce antibodies that will inhibit the bioactivity of FSH. Therefore, the hFSHR sequence was aligned with that of all other known G-protein coupled receptors. An area
