The use of an anti-gonadotropin-releasing hormone vaccine for immunocastration of male pigs has been recently approved in the European Union. This technique is potentially useful for avoiding both castration-associated pain for the animal and boar taint in pork. However, some animals may escape immunocastration and be slaughtered as entire males, potentially exhibiting boar taint. Therefore, it is important to check the efficacy of immunocastration on the slaughter line. To achieve that, the currently proposed method, based on testis weight, is not fully reliable because there is some overlap in the distributions of testis weight between immunocastrates and entire males. On the basis of literature data on the effect of immunocastration on the development of accessory sex glands, this paper provides evidence that the weight of seminal vesicles might be a much better criterion for checking the efficacy of immunocastration, because their size decreases more rapidly, and to a greater extent, than that of the testis.
一种用于公猪免疫去势的抗促性腺激素释放激素疫苗最近在欧盟获得批准。这项技术对于避免动物的去势相关疼痛和猪肉中的公猪膻味可能很有用。然而，一些动物可能逃避免疫去势并作为完整公猪被屠宰，可能会有公猪膻味。因此，在屠宰线上检查免疫去势的效果很重要。为此，目前基于睾丸重量提出的方法并不完全可靠，因为免疫去势公猪和完整公猪的睾丸重量分布存在一些重叠。基于关于免疫去势对附属性腺发育影响的文献数据，本文提供了证据表明精囊重量可能是检查免疫去势效果的更好标准，因为它们的大小比睾丸减小得更快，且程度更大。
