Hatha yoga is a moderately-paced, catch-all name for the vast menu of poses that are practiced wherever you can roll out a sticky mat.
An 1100 lb horse on a dry forage diet at an average temperature of 68 degrees Fahrenheit will need a minimum of 6-7 gallons of water per day or 48-56 lbs of water, and many horses will drink more water than the minimum.
Premium horse feeds are commonly tagged at 0.6 ppm selenium, or 0.6 mg/kg of feed. This equals 0.273 mg per pound of feed. (0.6 mg/kg divided by 2.2 kg/lb. = 0.273 mg per pound of feed) Thus, if you feed 5 lbs per day of a 0.6 ppm selenium feed, you are providing 1.365 mg of selenium per day.
