Horses at maintenance have significantly lower nutrient requirements than horses in moderate work.
Let’s use digestible energy (DE), or calories, as an example:
- An average 1,000 lb horse in moderate work requires a minimum of 21.2 Mcal (21,200 kcal) per day to maintain body weight.
- An average 1,000 lb horse at maintenance requires a minimum of 15.1 Mcal (15,100 kcal) per day to maintain body weight.
That’s nearly a 30% reduction in calorie requirements when a horse goes from moderate work to maintenance.
To put that into human terms, it’s similar to going from a 2,000calorie per day diet to a 1,400 calorie per day diet.
What would happen if you only needed 1,400 calories per day to maintain your weight, but continued eating 2,000 calories every day for a month?
As workloads decrease, this is a great time to re-evaluate your horse’s nutrition program and make sure calories in are matching calories out.
