Nutritional supplements are widely used in the equine industry with the aim of improving horse health, sports or reproductive performances. Over the years, a number of studies have focused on investigating the effects of several dietary compounds on the quality and preservation of stallion semen. This paper reviews the literature available on the use of nutritional supplementation for the improvement of reproductive performance and semen quality in equine species, critically appraising the benefits and negative effects of several compounds found in complementary feeds such as PUFAs from different sources, vitamins and antioxidants, carnitine and botanical extracts. Different nutraceuticals have been highlighted to improve stallion fertility by providing optimal levels of antioxidants, with the most promising results obtained by the combination of PUFAs and antioxidants that resulted to be essential for the maintenance of normal reproductive functions and the reduction of cryodamage in cooled and frozen equine semen.
营养补充剂在马术行业中被广泛应用，旨在改善马匹的健康、运动或繁殖性能。多年来，许多研究都集中在研究几种膳食化合物对种马精液质量和保存的影响。本文综述了关于营养补充剂在提高马属动物繁殖性能和精液质量方面的应用的文献，批判性地评价了在补充饲料中发现的几种化合物的益处和负面影响，如来自不同来源的多不饱和脂肪酸、维生素和抗氧化剂、肉碱和植物提取物。已经强调了不同的营养保健品通过提供最佳水平的抗氧化剂来提高种马的生育能力，最有前途的结果是通过多不饱和脂肪酸和抗氧化剂的组合获得的，这对于维持正常的生殖功能和减少冷却和冷冻马精液的冷冻损伤是必不可少的。
