HOW’D YOU DO? (Answers below.)

1. B is correct. A horse without enough protein in his daily ration will lose muscle and shape along his topline, even while the poor-quality grass hay he’s eating gives him a pot belly. If you’re in doubt, have the nutritional content of your hay tested, then supplement with a protein-rich commercial feed if need be. A mature horse in hard work should have 10% to 12% protein in his daily ration to build and maintain muscle.

2. C is correct. Excess fat can spike a horse’s risk for developing insulin resistance, a diabetes-like condition that can lead to a life-threatening founder episode if left unchecked.

3. T is correct. Horses’ diets can be deficient in many different vitamins and minerals, but selenium is the most commonly lacking nutrient, especially in certain areas of the country.

4. B is correct. Blister beetles cause extensive burning of a horse’s mucous membranes. Severe blister-beetle toxicity can lead to colic, shock, damage to the kidneys or heart, and even death.
