Patchy fat deposits over ribs. In other areas (including parts of Colorado, Wyoming, and North and South Dakota), forages may contain 5–40 ppm of selenium, which is sufficient to produce clinical signs of toxicity (see Selenium Toxicosis). Today copper is known to function as an essential co-factor for numerous enzymes in the body, which makes it an important mineral, even if only required in trace amounts. The dietary copper requirement for horses is probably 8–10 ppm, although many commercial concentrates formulated for horses contain >20 ppm. However, upper safe limits have not been established, and although excesses are usually efficiently excreted by the kidneys in healthy horses, acute hyperkalemia caused by the rapid absorption of concentrated salt mixtures can induce potentially fatal cardiac arrhythmias. Many horses suffer with copper deficiency, making the horse’s coat and skin appear dull. Like zinc, its uses were centered around constructing metal objects, most commonly in the form of the copper alloys, bronze, and brass. Our requirements call for 4.5 mg/lb.
