I have some questions about feeding. I know they may seem common sense, but I want to make sure I'm not making any mistakes. I have an 11 year old mare who is pretty fat right now. I exercise her as much as I can, but unfortunately, I am a full-time student and so taking the time to giver her regular exercise is challenging, even more so because she is being kept an hour away with my parents. She is kept primarily outdoors at this point. She is going to be bred in the spring (I will be finished school once the foal is born) and I know being overweight and in foal can be dangerous. I also want to get her down to a healthier weight before she is bred as I don't want her to be losing weight while in foal which is why I want to start this now so she doesn't lose weight too quickly. The other part of this is I live in Alberta, Canada and the winters here can be quite demanding on a horse kept outdoors. I want her to lose a few pounds, but I also want to make sure her calorie intake is high enough that she is able to stay warm. Any insight would be appreciated. I've included a picture of her below - and you can clearly see that she's overweight. She has lost some weight since then, but is still pretty chunky. Over the summer, she was mainly on grass, and in winter, we tend to feed her grass or timothy hay.
