The actual daily amount of water that most horses need to consume (at a minimum) to maintain body functions and remain properly hydrated is from a half gallon to a gallon per 100 pounds of body weight.
On feeds which can be fed at a maximum of 50% of the diet (not that horse owners generally feed it that high), the limit is 0.6 ppm added selenium. Chronic selenium toxicity occurs at about 10X the FDA limit, so there is a pretty good safety margin. How much does a horse actually need? A horseâs basic daily requirement for selenium is 1-3 mg per day. Some chronic selenium symptoms might appear above 10-15 mg/head per day. To figure out what your horse is consuming, have your hay/pasture supply tested, and then add the amount it is consuming from the hay, to the amount it is consuming from any feed & supplements, and you will know if you need to make any adjustments to your horseâs overall diet.
