I'm actually a fan of having my own feed mixed at the mill. That's what the other horses that live here get and what the above mentioned horse ate most of his life but there came a day when that just wasn't working for him any more. So...it was either try something else or have him put down before he was totally emaciated. I chose trying the shiny, colorful bags over euthanasia because I love that horse, he did whatever I asked of him for many years, and other than a weight issue and general old age stiffness there wasn't a thing else wrong with him. I can't argue that it's more expensive but it does work. At 29 he probably doesn't have a lot of time left but I'm going to enjoy each and every day I still have left with him and in the end I'm going to miss him and not the money I spent keeping him healthy.First, be sure he is free of parasites. Use a real worm medication. Second, get his teeth looked at by someone that really knows what he is doing. Horses teeth develop points that tear into the horse's mouth, making eating painful. Third, slowly increase the quality of his feed. If you are rich, buy lots of bags of Horse feed. It comes in pellets and cubes, in shiny colorful bags. If you aren't rich, get the mill to mix you some feed. About half cracked corn, 20% oats, 20% soybean meal, vitamin mineral mix and enough molasses to keep the stuff mixed up. If you are on the non-GMO bandwagon, replace the corn with oats.
Old horses, like old people don't digest as well and get chilly. A thin horse will suffer without a blanket in bad weather. Get an insulated horse blanket.
I totally agree...Triple Crown Senior is my go to preference for Senior feed. I have also used Nutrena Senior. Both are good. If your horse has mouth issues, either of these feeds are easily broken down when wet.If the horse is eating hay and still needing weight, then it may be time to add grain/concentrates. Personally, I'd go with a pre-mixed Senior feed, because they tend to be palatable and the ingredient mixture is usually consistent. I personally love Triple Crown Senior, but currently feed Nutrena Safe Choice Senior.
