Survivor is an easy to mix colostrum for lambs and calves. Survivor provides the energy and stimulus for the newborn animal to suckle naturally on the mother. It is essential that Survivor is fed to the newborn animal within 4 hours of birth and if necessary, repeat 4 hours later. Survivor protects from Johne’s-free disease, a contagious infection that primarily affects the small intestine of calves and helps to build a strong immune system.
