The application of artificial insemination (AI) makes full use of the sperm of boars with excellent qualities and improved economic benefits (Berger & Conley, 2014). The storage of boar sperm at 17°C, as a common sperm preservation technique, inhibits sperm movement and reduces energy consumption such that sperm survive longer in vitro (Zhu et al., 2020). However, the quality and fertility of boar sperm decrease with storage time (Basioura et al., 2018). The plasma membrane of boar sperm contains a high concentration of polyunsaturated fatty acids and has a low cholesterol/phospholipid ratio (Davis, 1981). These characteristics make boar sperm more
