Semen quality directly affects the reproductive efficiency of sows and the health status of their offspring, and is therefore a key determinant of overall pig production efficiency. Dietary fiber has long been regarded as a “non-nutritive substance”. However, recent researches have progressively revealed that it not only exerts basic physiological functions such as promoting intestinal motility and optimizing microbial community composition, but also demonstrates significant ameliorative effects on boar semen quality. This review systematically summarizes the effects of dietary fiber on semen quality and its underlying mechanisms, aiming to provide theoretical guidance for the rational application of dietary fiber in the diets of breeding boars.[Chinese Journal of Animal Nutrition, 2026, 38(8):5563-5570]
