Research at Oklahoma State University resulted in the following suggestions to reduce death loss, morbidity and treatment costs and increase the productivity of newly received stocker cattle.


  • In determining sick animals, use 104 degrees F as a fever point. If an animal is not visibly ill but has a body temperature of 104 degrees F or higher, treat him as sick. Pull as sick all visibly ill animals, regardless of the body temperature.
  • Be prepared to treat cattle as they come through the chute. Have treatments planned in advanced and select drugs before cattle arrive. Use drugs which remain in the tissues for 24 hours, not just for 8 to 12
    hours. Vaccinate and worm sick cattle the same as non-ill cattle.
  • Identify the sick animal for future reference through the use of an ear tag, a forehead tag cemented to the forehead, or a grease stick and keep records of physical signs, body temperature and medication.
  • Keep sick cattle together and away from non-ill cattle.
