Abstract
Infrared thermography (IRT) can be used successfully to differentiate abscessed implanted ears from nonimplanted ears 8 days postimplanting. Abscessed ears averaged 5.7EF warmer than nonimplanted ears when ambient temperature was 60 to 63EF. Average daily gain and feed efficiency were reduced 8.9% and 8.3%, respectively, over the 91-day feeding period for cattle with abscessed implants compared to cattle with normal implants. Dry matter intake was not affected by an abscessed implant and averaged nearly 18.0 lb/head/day for both treatment groups. Abscessed implants reduced economic return by $17.70 per head.
