Abstract

The low resistance of boar sperm to cryopreservation dictates that adding antioxidants and energetic substances to the diluent to improve sperm quality is necessary. This study is designed to assess the impact of various concentrations of safflower polysaccharides (SPSs; 0, 0.5, 1.0, 1.5, and 2.0 g/L) on the quality of boar sperm following freezing and thawing. The results of the study showed that the supplementation of 1.5 g/L SPS significantly enhanced the motility, average path velocity, straight-line velocity, curvilinear velocity, beat cross frequency, acrosome integrity, plasma membrane integrity, mitochondrial activity, and DNA integrity compared with the control group (p < 0.05). In addition, the supplementation of 1.5 g/L SPS significantly enhanced the total antioxidant capacity, superoxide dismutase activity, glutathione peroxidase activity, and catalase activity while significantly decreasing malondialdehyde and hydrogen peroxide content (p < 0.05). Therefore, the supplement SPS has potentially positive implications for improving the quality of cryopreserved boar sperm, and the recommended concentration is 1.5 g/L SPS.

期刊介绍： Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
