Respiratory Disease • Journal of the American Veterinary Medical Association (JAVMA 219:1122-1127, Oct. 15, 2001). • Best information that has ever been available to study death risk in feedlot cattle • Based on data collected on 21.8 million cattle entering 121 large feedlots over six years
Respiratory Disease • Cattle placed in feedlots in the major feedlot areas of the US more likely to die of respiratory disease in 1999 than they were in 1994 • Continual upward trend in death risk each year. • 1994 to 1999 death loss percentage from 1.03% to 1.42 % (38 % increase in death loss risk) Journal of the American Veterinary Medical Association (JAVMA 219:1122-1127, Oct. 15, 2001).
Respiratory Disease Journal of the American Veterinary Medical Association (JAVMA 219:1122-1127, Oct. 15, 2001). Their conclusion: We don’t know why death losses increased…cattle only slightly smaller on entrance My question: More calf-feds? Conclusion: The large, high plains feedlot is a poor weaning pen!!

Losses from Respiratory Disease • As long as they don’t die, perform well, and I didn’t spend too much treating them, I’m OK. Right?
University Study Impact of Bovine Respiratory Disease During the Receiving Period on Feedlot Performance and Carcass Traits T.C. Stovall, D.R. Gill, R.A. Smith and R.L. Ball
University Study • So why did these cattle respond to treatment so well (no realizers, total compensation)? • ???? • Time of treatment?
Vaccination Programs • Pre-vaccinated calves are probably overpriced and it doesn’t do much good anyway. Right?
Health as Part of “Quality Cattle” • Two-tiered marketing system • “Commodity cattle” • “Quality cattle” or “Grid cattle” • Are health verified cattle worth more just for improved health or is there additional value?
