My Oldenburg gelding is an easy keeper. I bought him a Natural Alternative Grazer(N.A.G. Bag) and now he has hay all the time, he is happy and he is not getting overweight as he tends to do in the winter. In the past he would park at the round bale and eat 24/7. The wasted hay was gross. He would pull out the best and stomp and poop on the rest. Best of all, he isn't as aggressive to the other horses on the same bale.
I am guessing that my feeding time is cut in half, never mind the spring cleanup of scraping yucky hay. Nag Bags are at Nag Bags | Natural Alternative Grazers | Mandy Blais)
