论文摘要

Castration of male animals is a common practice in the meat industry aimed at reducing aggressive behavior, preventing unpleasant flavor, and controlling undesirable breeding. For many years, mechanical castration and surgical castration have been practiced to sterilize the animals. However, these castration methods are not humane because of the associated risk of death, pain, and stress. Recently, immunocastration targeting the hypothalamic-pituitary-gonadal axis(HPG) axis has been reported as an animal-friendly approach that circumvents many of the concerns with conventional castration, and suggested by researches as an alternative to surgical castration. However, there is no compilation of updated information on the use of immunocastration in sheep and goats. Therefore, this review aims to summarize the developmental process from traditional surgical castration to immunocastration and to screen the process of immune targets. It also compares the respective advantages and disadvantages of traditional castration technologies and immunocastration, in particular including analyses in the characteristics, features application and welfare benefits of immunocastration in sheep and goats were also analyzed.
