Calves, yearlings or animals with other parasites or poor nutrition tend to be more susceptible to ringworm and warts, which often develop on the ears, head and neck in the late winter and early spring, according to University of Missouri Extension livestock specialist Eldon Cole. Close quarters in the cooler months help pathogens pass between animals, and ear tattoo equipment that isn't disinfected between animals can also spread infection.
