1. Foot Rot • Infection in the foot and surrounding hoof • Must have a break in the skin for the bacteria (Sphaeophours Necrophorus) to enter • Occurs worldwide • Organism lives in the soil, occurs both in muddy and dry conditions

2. Symptoms • Foot becomes warm (fever) • Swelling (can go as high as the fetlock joint) • Lameness • Lose weight, milk production declines

3. Treatment • Trim and clean foot • Spray foot with iodine solution or coppertox (watch for adverse reaction to these) • Treat with sulfonamides or antibiotics • Animal should recover in a few days

4. Prevention • Foot baths • 2 to 5% copper sulfate solution ( do not use for sheep, Cu is toxic to sheep) • Saturated zinc oxide solution • Provide mineral supplement containing iodine (ethylenediamine dihydroiodide (EDDI) is the best source of iodine). Fed at the rate of 200 to 400 mg/head/day in cattle feedlots prevent foot rot. • Zinc supplementation had been shown to decrease the incidence of foot rot (ZinPro =Zinc methionine)
