I am considering feeding my horse oat hay for the winter, as it is cheaper and I hear is a little fattier.
I have a Thoroughbred mare, with a hyper speed metabolism. Impossible to keep weight on and keep calm!
I understand Oat hay has a lot of sugar, but it will be winter and I won't be riding as much anyway. But there is a lot of nitrate? What is that and how is too much harmful?
What are your guys' opinions on it?
