Mycotoxins.

This research article focuses on the impact of mycotoxins, a type of toxin produced by molds, on horses. It highlights the negative effects of consuming contaminated feed and the severe health complications that can result, emphasising the importance of high-quality feeds as a prevention strategy.

Understanding Mycotoxins in Horses’ Diet

The research article explains the potential harm caused by mycotoxins in the diet of horses. These are toxins produced by molds that can contaminate various elements in a horse’s diet, particularly grains and forages.

• Horses could consume a range of mycotoxins, depending on the type of feeds and grains they consume.
• Different mycotoxins can result in different forms of toxicosis, such as fumonisins or aflatoxin from grains, tremorgenic mycotoxins from dallis grass, or slaframine from red clover.

The Effects of Mycotoxins on Horses

The effects of these mycotoxins on horses can vary in terms of severity and timeframe.

• Fumonisin toxicosis is often severe and fatal to horses.
• Aflatoxin may result in either acute or chronic illnesses, leading to debilitation over time.
• Other mycotoxins may cause moderate to mild signs of poisoning, which often recede once the contaminated feedstuff is removed from the diet.

The study notes that in comparison to other domestic animals, horses may have a low prevalence of reported incidences of mycotoxicoses. However, they are particularly sensitive to fumonisins.

Preventing Mycotoxicosis in Horses

Due to the absence of effective therapies for mycotoxin poisoning, the paper emphasizes the need to focus on prevention. The most reliable way to prevent mycotoxicosis in horses is to ensure high-quality grains and forages are provided to them.

• Preventing mycotoxicoses involves maintaining high standards of quality control in sourcing and providing feed for horses.
• Since contaminants cannot be easily removed once present, it is crucial to prevent them from entering the feed chain in the first place.
