A combination of heat, water and pest pressure can increase the risk of pinkeye and foot rot in cattle. NDSU Extension veterinarian Dr. Gerald Stokka says there are certainly differences in susceptibility to organisms that can cause infection. Regardless, treatment with antibiotics is required to impact the course of infection and inflammation. “There are several antibiotics labeled for pinkeye, so consult with your veterinarian for the best option,” says Stokka. “Foot rot is a little different, as the organism that carries it can be in the soil. If you see swelling between the toes, treatment is needed.” With infection comes pain, which can lead to decreased grazing activity in cattle. Therefore, treatment is always preferred and more successful earlier in the course of infection.
