Bucket covers are very useful when you need to prepare your horse's feed in advance, particularly if you need to ask someone else to feed them while you are out. The feed can be mixed ready and covered to protect it from vermin and contamination. Some covers also have labels to ensure that the correct bucket is fed at the correct time. They are handy when you are away competing with your horse overnight and need to prepare their feed in advance.  Manger covers are also available which are shaped to fit a corner manger.
