Here at Family Circle Farms & Farm Animals Rescue we use only RE-Sorb on all our new Calves that are given to use to save. Using this product as the directions tell us, we have about a 80% recovery rate from Scours. Early treatment is always the best outcome. We live in the State of Maine and winter comes every year, along with the Scours. On a good winter I will have worked on about 50 young and new born Calves. Some day I'm hoping to have a 100% winter , before I retire. Thank You for taking the time out of your day or night to read this, and please believe me this is no bull.
