| 公猪的重要性越来越得到广泛的关注。尽管种公猪在猪群中占据比例不高，但是种公猪的繁殖性能可以直接影响母猪的妊娠率和产仔数，进而影响猪场的整体经济效益。公猪的精液品质是其繁殖力的基础，同时也是发挥公猪遗传性能的重要保障。文章综合了近年来国内外研究公猪营养对精液品质及繁殖力的调控，从膳食纤维、蛋白质及氨基酸、多不饱和脂肪酸、微量元素及维生素、植物提取物、有益菌群等方面分析了它们如何改善公猪精液品质，但是有关研究还很不完善、不系统。因此，需要根据种公猪不同品种、不同生长阶段、不同环境条件下对各类营养物质的需求来制定合理、合适的种公猪饲料配方，以期发挥种公猪的最大潜力和价值。 |

| The importance of boars is getting more and more attention. Although the number of boars is much less in the whole population in swine industry, the fertility potentials of boars can influence the pregnancy rate and the number of offspring directly, and even affect the total economic benefits of the swine industry. The quality of boar semen is not only the foundation of fertility, but also the important guarantee to give full play to the genetic performance of boars. This review summarized the recent publications of nutrition regulation of boar semen quality and fertility, and discussed the effects of dietary fiber, protein and amino acids, polyunsaturated fatty acids, trace elements and vitamins, plant extracts, beneficial microbe on the boar semen quality and fertility. However, these researches are still not perfect or systematic. To maximize the potential and value of boars, many more studies are needed to explore the boar formulations based on different breeds, different growth stages, and various environmental conditions. |
