It wasn’t until recently that the significance of mycotoxins was realized, said Thomas Buckley, MS, head of microbiology at the Irish Equine Centre. Buckley presented “Coping With Mycotoxin ...

Fescue Field Management 
It is estimated that 35 million acres of United States pasture are planted with tall fescue (Festuca arundinacea), and roughly 700,000 horses graze these fescue pastures. This plant is a cool-season plant, so it grows in cooler climates, is tolerant of poor drainage and poor soil, and has a good regrowth after grazing. It also lasts longer into cool ...

Forage Alternatives 
Man might not live by bread alone, but horses can live on forage just fine. As grazing, herbivorous animals, forage (grasses and plants that grow on pastureland) is what they're designed to eat. Other components of the equine diet--grains, fats, apples, and carrots, for example--are merely the "bells and whistles." It's high-fiber grasses and legumes ...

Hay FAQ 
Ask any Average Joe on the street what a horse eats, and chances are he’ll answer, ‘hay.’ Even those who’ve never picked a foot or mucked a stall recognize that fibrous dried forage as the foundation of a horse’s diet. Given that, it’s surprising how little respect hay gets. Perhaps it’s not as sexy as a bag of high-powered grain or a bucket of space-age ...

British Horse Society Warns Of Dangers Of Ragwort In Hay 
The British Horse Society has issued a warning to all horse owners to beware of ragwort in hay. With a high prevalence of ragwort last summer, it is virtually impossible to guarantee that hay is completely ragwort free, in fact the BHS received many reports of fields absolutely full of ragwort being cropped for hay. The presence of ragwort in hay is ...

Alfalfa Cubes: An Alternative Forage 
Good quality forage is the basis of feeding programs for all horses. When hay is being fed, horse owners need to select a hay that is nutritious but also free of dust and mold. However, when mold-free hay is not available, horse owners can consider the use of alfalfa cubes as a viable forage alternative. The difference between alfalfa hay and the alfalfa ...

Hay Alternatives 
Although regular baled hay is the mainstay of equine diets across North America, it's sometimes more trouble than it's worth. Heavy to stack, bulky to store, prone to vitamin breakdown, and -- heaven forbid! -- also spontaneous combustion, not to mention dust and molds that can aggravate both human and equine respiratory allergies, hay is hardly a ...

Fiber Facts 
Grazing is a full-time job for horses. Given their druthers, they'd graze for 12 hours or more every day, their broad, flat teeth and sideways chewing motions making short work of the tough, stemmy grasses and weeds they favor. Like all true herbivores, horses get most of their daily energy requirements from eating plant fibers. Yet, ironically, horses ...

Buying and Storing Feeds 
Feed is a major expenditure for any horse owner, and we all want it to be money well spent--both in terms of nutrition and quality. Getting the best value often means buying and storing feed in bulk. But unless that's done properly, you might find you lose a major portion of your investment to mold, insect infestation, or water damage, any of which ...

Hay, Look Me Over 
Horses are superbly adapted herbivores. From their wide flat molars--designed for grinding tough, gritty stems--to their gastrointestinal tracts--which process the nutrition bound in fibrous plants--they are equipped to get the maximum benefit out of food sources that many animals reject. Evolution also has provided horses with a talent for speed, ...
