Use of nutraceuticals in the stallion: Effects on semen quality and preservation.

Abstract: 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.

This research article investigates the impact of nutritional supplements on the quality of stallion semen. It highlights that certain nutraceuticals, particularly combinations of PUFAs and antioxidants, can enhance reproductive performance and protect the integrity of cooled and frozen equine semen.

Understanding Nutritional Supplements in Equine Reproduction

  • The paper first sets the stage by discussing the popularity of nutritional supplements in the horse industry. These products are often used with the hope of enhancing horses’ overall health, performance in sports, and in this case, reproductive capabilities.
  • Notably, the article zeroes in on the potential influence of several dietary compounds on stallion semen quality and preservation. These compounds include polyunsaturated fatty acids (PUFAs), vitamins and antioxidants, carnitine, and botanical extracts – components that are usually found in complementary feeds.

The Role of PUFAs and Antioxidants

  • The researchers underscore the promising role of antioxidants and PUFAs in enhancing stallion fertility. Antioxidants are substances that can prevent or slow damage to cells caused by free radicals. Meanwhile, PUFAs, specifically omega-3 and omega-6 fatty acids, are essential fats that the body cannot produce on its own.
  • The study calls attention to the efficiacy of combining these two components, suggesting that they may play a crucial part in maintaining normal reproductive functions and reducing what’s termed “cryodamage” — the damage caused to sperm during the preservation process.

Preservation of Equine Semen: Cooled and Frozen

  • This part of the paper explains how the freezing and cooling of equine semen can cause cryodamage. Cryopreservation is a common method used to store and transport semen for artificial insemination. Despite its practicality, it can unfortunately lead to cellular damage, lowering semen quality and hence the chances of successful fertilization.
  • In this context, the article suggests, the identified combination of PUFAs and antioxidants can provide some protection against the negative effects of the preservation process, offering a promising approach to improving the preservation of equine semen.
