During the recession. I chose to not breed my own mares, and instead took in some young horses who's owners could no longer care for them. I have several friends that did the same. My trainer took in many, but one in particular was a 1. So I have actually had 1st hand experience and have seen others close up. In my experience it takes about a year to get a young hot blood horse from a 2 back to a 5. It took about 2 years for the trainer and then the horse new owner to get him from a 1 to a 5. This is with free choice Timothy, alfalfa and senior feed. It takes almost the fist month to get them built up to a proper diet. Horses that are down like this in the winter are hard to bring up because they burn so much for heat. Young horses are still growing and nutrition will go to the growth. Many hot bloods take far more calories than cold /warm bloods. TBs are notorious for being hard to build back up. The Rescue or legal owner of this horse did not post these pictures, I doubt that there was permission to post them. The Rescue did not put this horse in this state. For all we know the horse was full of ulcers and worms on top of the starvation. The horse is gaining weight and is in a healthy looking environment. I see no wrong doing on the rescues part . I would be very careful not to turn this into a witch hunt.
