What Is The Best Horse Feed For Weight Gain On The Market?

There are a great many horse owners who would give their back teeth to have a horse who didn’t put on weight too easily, but there are an equal number who wish their four legged friend would put on a bit of podge. Natives tend to run to fat far easier than the hot blooded or Thoroughbred types, and if you have one of these slimmer horses then you may wish to consider adding a little something to the feed to bulk them out a little. Older horses, like older humans, can often struggle to keep fat on them.
