We compared proteomic profiles of male pig muscles after active immunization against gonadotropin releasing hormone (GnRH) and surgical castration. Longissimus dorsi samples were collected from immunocastration (IC) and surgical castration (SC) groups (n = 15 each). Muscle proteins were extracted and then identified by data-independent label-free nano LC-MS/MS. A total of 610 proteins were identified, 50 of which were differentially expressed (P < 0.05) between immuno- and surgical castration. Twenty-two of 50 differentially expressed proteins were higher in abundance for IC group and 27 proteins with abundance change folds greater than 1.5 differed with castration methods. Proteins involved in cytoskeleton and immunity were abundant in IC group. Several heat shock proteins (HSPs) and laminins were abundant in SC group.
