Thanks everyone for all the info....a lot to chew on!!
Al's ribs are not as noticable now as they were one month ago. He def has put on some lbs. We are going to start him on a joint supplement this week.
We are so pleased with how he looks and acts. He is a totally different horse than when we bought him. He is happy, interested, and feeling a lot better. He was low guy in a pasture with many horses. Round bales were tossed out as feed with the alpha guys getting most of it. He had nip marks on his beautiful bay coat. And one nasty bite.
Right now he is on Nutrena Safe Choice, 2 scoops a day with pasture 5 days a week and we turn him out on the weekends. Also, three hay feedings.
Take away the stress of having to fight for his food, he is coming around very well.
I wish I had found him years ago.
