In these trials, the number of false negatives with fever as a diagnostic test predictor (i.e. those that died and did not have a fever) was 608 head. The number of false negatives with Whisper lung score of “1”as a diagnostic test predictor was 210 head, a reduction of 65 percent. The number of false negatives with a combined fever and Whisper lung score was 102 head 506 head or 83 percent less than fever alone as diagnostic test predictor and 108 less head than Whisper lung score alone as a predictor of fatality.
When used in a production animal setting, Noffsinger says, Whisper is neither perfect nor infallible. However, the utilization of auscultation via Whisper has resulted in better case definition, improved risk assessment, stratification of cattle by lung score, and targeted antibiotic treatments. The new audio technology, he says, will change the way you “see BRD.”
The Whisper Electronic Stethoscope was developed by Geissler Corporation and will be marketed by Micro Beef Technologies.
