The way I understand equine nutrition is this: if your horse is too thin, he needs more food. While Izzy isn't "thin," he also doesn't have anything extra which means he needs at least a bit more food. There are three "types" of food for horses: fiber (hays and other forages), starches (grains like corn, oats, and barley), and fats (oils, rice bran, seeds).
I was hoping that the Cool Calories would do that, but alas, it did not. To check that Thursday's ride wasn't just due to "one of those days," I did not give Izzy the Cool Calories in his Thursday lunch bucket. On Friday morning, I hopped up on him and found a PERFECT gentleman. In fact, I had to give him a pretty hard kick to get him to even trot. From the moment I got on, he was pliable, malleable, and soft as butter. He was that way on Wednesday, too, as well as over the weekend. Thursday, the morning after the full dose of Cool Calories, was the only day where he was anything but pleasant. While this is a teeny tiny data set from which to draw a conclusion, I am going to anyway. A single scoop of Cool Calories was about the same as giving the Big Brown Horse crack.
I also know that Izzy tolerates flaxseed oil very well, and we all know that it's rich in protein, dietary fiber, and Omega-3 fatty acids. Unlike flaxseed oil, this stuff is easy to feed, and since it's already milled, I can just scoop and top dress his beet pulp and rice bran with no grinding. Cost-wise, it's also really cheap at $0.39 for a two-ounce serving.
Let's hope the milled flaxseed adds calories but not energy because if not, Speedy's going to be eating flaxseed for six straight months whether he likes it or not!
