Well, he doesn't have a fever. What was the last dewormer that he had? Do you rotate dewormers to make sure you cover a wider variety of worms?
He looks awful skinny to be a dominate horse during feeding time. Granted, not being worked is going to make him loose muscle mass, but not to that extent. Obviously it's best if you get a vet out right away, but we all know how money problems can be. Try giving him more hay, grain him, maybe a senior feed that has beet pulp/rice bran in it? A good diet will get him to gain weight but if he has under lying health issues, no amount of food is going to help.
Keep an eye on him and have the vet out when you can.
I had a mare that had a bacterial infection and dropped weight like that. She was lathergic, still had an appetite but no amount of food helped her. After 10 days of antibiotics from the vet, she was a new horse, and within 5 weeks, she was at a healthy weight again. It was in February she caught it. Vet was super confused by how but with a horse, anythings possible...
