My hubby and I rescued a 20 year old gelding in October. He was a bag of bones. My friend said to start feeding him at least 2 times (preferably 3) a day of alfalfa cubes and equine senior. We did that, soaking the alfalfa and mixing it with the senior. The devil would eat sit and pick out the senior and leave the cubes. Was told try beet pulp. Again, he picks out the senior and leaves the beet pulp. Since, all three of them have free choice hay, he has picked up some weight, but needs more. Even our other two horses turn their noses up at the soaked beet pulp and alfalfa cubes. What am I doing wrong? I have tried leaving out the senior feed to get him or the other to eat it and they just turn away from it. I have tried adding sugar, molasses, syrup, minerals, and suppliments. All three of them turn away form it. I have tried buying the senior feed in it and they will all pick it out. Are they just that picky? I need to get more weight on the old guy, but he seems to be fighting me every turn. The vet has checked him out and has said his teeth are fine and he is in good health just underweight.
