Immunocastration (vaccination against boar taint) is an alternative method to prevent boar taint without the need for surgical castration. This study investigates the evolution of boar taint compounds in serum and fat, serum steroid compounds as well as behavior in immunocastrated pigs from 3 sire lines: 15 stress positive Belgian Piétrain (BP), 20 stress negative French Piétrain (FP), and 20 stress negative Canadian Duroc (CD). Hormone and boar taint compounds in serum were determined at 4 time points; boar taint compounds in fat were determined at 3 time points. Behavior, skin lesions, animal and pen fouling were also recorded before the first vaccination (<V1), between the first and second vaccination (<V2), and after the second vaccination (>V2). Aggressiveness, eating and drinking and general activity behavior declined from <V1 to
免疫去势（针对猪体味的疫苗接种）是一种替代方法，可以在不进行手术去势的情况下预防猪体味。本研究调查了 3 个公猪品系（15 头应激阳性比利时皮特兰猪（BP）、20 头应激阴性法国皮特兰猪（FP）和 20 头应激阴性加拿大杜洛克猪（CD））的血清和脂肪中的猪体味化合物、血清类固醇化合物以及免疫去势猪的行为变化。在 4 个时间点测定血清中的激素和猪体味化合物，在 3 个时间点测定脂肪中的猪体味化合物。在第一次接种疫苗前（<V1）、第一次和第二次接种疫苗之间（<V2）以及第二次接种疫苗后（>V2），还记录了行为、皮肤损伤、动物和猪圈污染情况。所有公猪品系的攻击性、进食和饮水以及一般活动行为均从<V1 下降到<V2 和>V2。BP 猪比 FP 和 CD 猪更干净。尽管免疫去势对所有公猪品系都有效（降低了血清中的睾酮、雌二醇和雄烯酮），但一些个体猪的脂肪中仍存在雄烯酮或粪臭素水平超过临界值。虽然免疫去势机制对雄烯酮有效，对三个公猪品系的粪臭素也有效，但仍然存在一定程度的风险，即胴体中的猪体味化合物含量超过临界值（分别为 1.9%和 3.7%）。
