K-State veterinarian urges cattle producers to watch for coccidiosis in weaned calves

By Jason Vance As cattle producers work through fall weaning and marketing, K-State Extension beef veterinarian AJ Tarpoff is reminding them to watch for signs of coccidiosis, a parasitic disease that can affect calves already dealing with the stress of seasonal management changes. Weaned calves are particularly vulnerable this time of year as fluctuating temperatures combine with the added stress of weaning, commingling, transportation and marketing. While producers often associate these stressors with respiratory disease, Tarpoff said coccidiosis can also become a concern. Coccidiosis is caused by a protozoal parasite to which virtually all cattle have been exposed. Although exposure is common, stress and other management factors can contribute to a resurgence of the disease. Tarpoff said producers should watch for several symptoms, including straining to defecate, loose manure and small specks of bright red blood in the manure.
