I think my mare looks a little thin and I am starting to be able to see her ribs now. They get more and more prominent but she isn't emaciated. I do not want it to get to that point. I have heard that depending on what you give your horse to gain weight, they will put it on differently. She needs to gain weight all over. What is the best feed/way to do that? Should she get more hay, grain, vitamins, etc.
Right now she is being lunged every other day and is turned out to a large pasture on days she is not lunged. Her feeding is 8 oz of grain in morning and night and 1 flake of hay three times a day, unless she is out to pasture then it is 1 flake twice a day. Plus I give her vitamins as directed for her weight per the directions. She is a 14 hand Arab who currently weighs around 800 lbs (per the vet check when I first got her but she has lost weight since). She was underweight when I got her due to no muscle and that is changing because I'm working her. Before she was just standing around in a stall, no pasture turnout. However, now she is getting a ton more exercise and I think her old feeding routine isn't giving her sufficient calories.
Thank you for your help.
