Cause.—Cows wading or standing in stagnant pools of water. Frequently stringy milk results from fungi entering the udder. This takes on an infectious form, and several cows may become affected at one time.

Symptoms.—Although the milk appear perfectly normal when first milked, it becomes stringy after standing for a few hours. If a needle is inserted in the milk and slowly withdrawn, the milk will adhere to the point and have a stringy appearance. If the cow is examined carefully, the temperature will be found to be elevated a degree or two, the appetite poor and the nose dry.

Treatment.—Feed laxative food and see that they have fresh water to drink. Also place two drams of Soda Bisulphite once or twice a day in a gelatin capsule and give with capsule gun. Do not permit the cow to come in contact with stagnant pools of water that carry this infection. Perhaps the best plan is to fence out all such stagnant pools of water.
