Several serious livestock diseases are caused by a group of bacteria called clostridia that can produce deadly toxins. Many cattlemen are familiar with blackleg, tetanus and enterotoxemia, but some may not be familiar with redwater.

Five species of lice parasitize cattle in the U.S. Four of these are blood feeders, and the fifth is a biting or chewing louse. Cattle with hair loss, an unthrifty appearance, and leaving hair on fences and other objects from rubbing may be a sign of lice infestation.

The best way to treat flies is to first understand what fly you are treating for. Remember: Face flies are found on the face, stable flies are found on front legs, and horn flies are found on the back and sides.

Summer is here, and that means cattle are grazing, and with it, dealing with parasites. Deworming is a herd management practice that can yield a significant return on investment.
