Selenium: A Balancing Act
Today's horse owners are very supplement-oriented. When a new supplement hits the market, many horse owners are tempted to use it if they think it will somehow improve their horses' health.

Antioxidants and Heaves  *
When a horse inhales mold spores or other irritants, neutrophils (specific types of white blood cells) release reactive oxidants--generally very reactive substances that can break down mold in the airways.

Nonenzymatic antioxidants, such as vitamin E, are critically important to protect horses from tissue damage and disease, and they might enhance immunity during these processes.

They come in various colors and sizes. Some weigh 50 pounds, others a pound or less. But how do we know which salt and/or mineral block to place before our animals?

Can You Influence Hoof Growth?   *
We ask an awful lot of an animal who walks on his middle toenails. Humans have recognized for centuries that the foundation of a horse's soundness lies in his hooves--"No foot, no horse" is about as basic a principle as there is.

Amazing Minerals  *
Of all the ingredients of a horse's diet, minerals are unique. They contain no carbon, which makes them inorganic molecules.

The first thing to address in this story is that most "bone cysts" are not typically "cysts," by strict definition.
