Feed comparison would be of most value to the most people I think, and interesting.
We all tout our favorite feeds and many of those feeds are regional, like Seminole, but that’s not truly a nutritional topic.
I had problems using the pounds to feed per day regime on the bag of feed. I just couldn’t get a handle on it mentally when if I knew that my horse needed 9K calories per day and the feed was 1500 calories per pound I can do that math fast. Two pounds of 1500 calorie feed is going to get me almost a pound of weight on the horse, if the horse is gaining at 8 pounds a week that means I have 8x3500 calories to play with and can back the feed down by what? Two pounds a day? Is that even a correct line of thought?
Maybe it relates to being a person that diets, so calorie counting is something I do often for myself. I’m trying to think of ways to make this valuable information more accessible, and save a few horses from starving due to sheer ignorance.[/QUOTE]
Well the good news is, yes you certainly can do all your energy/feed needs calculations in calories. In fact here in the USA, that’s all the energy info you will get. so if you are living here, then the only Joules and Newtons you need to worry about are how many Joules are in a Fig Newton, should you eat one!
All joking aside, the SI units are what we have to use if we plan to present a study at an international meeting, but back at home we all work in Calories (and in lbs as well no Kgs here!).
One thing to bear in mind is the huge size difference between horses and humans.
YOU are probably used to working in kcals aka Cals, with horses we work in Mcals, and yes an Mcal is a thousand kcals or a thousand Cals! So if you are used to thinking in terms of 2,000 kcals ( the normal energy requirement for a human of 150lbs) , remember your horse weighs 1,000lbs and is going to require energy in 8-10X that amount.
Also horses have hind end fermentation, which supplies a LOT of energy and is by far the safest form of energy for them.
Thus you have to follow certain restrictions when formulating a diet for horses, the number one being it HAS to be a MINIMUM of 60% fiber, preferably digestible fiber, but fiber for sure. If you feed a horse as little percentage fiber as most humans consume, they would for sure, colic, and many horses are such efficient fermenters that they can get 100% of their energy needs from their hind gut and need only a supply of vitamins and minerals on top the hay.
But by all means do your calculations in Calories.
