I totally agree with the high fat diet. My vet suggested Southern States Select as the best maintance diet for my horses. They have it in two forms, pelleted and textured. I go with the textured because of smell and the horse seem to enjoy the sweet taste.
I add a mix of vitamins and minerals to everyones feed, as well as a joint supplement.
Also the price per bag on the Select is about 8.50, cant beat that when you are trying to feed four very hungry pigs twice a day and pay the rest of the bills.
My husband and I are in our early twenties, we have a house, two cars and four horses. Saving money for us is very important, and if our horses are fine with the cheaper feed and it works well for them, then I am all for it. Some may not agree, but unfortunatly the expensive horse feed doesn't look to good when I have to eat it because we spend all our money on horse feed and none on people food.
