Portable Electronic Nose for Analyzing the Smell of Nasal Secretions in Calves: Toward Noninvasive Diagnosis of Infectious Bronchopneumonia.

ABSTRACT: The paper demonstrates a new approach to identify healthy calves ("healthy") and naturally occurring infectious bronchopneumonia ("sick") calves by analysis of the gaseous phase over nasal secretions using 16 piezoelectric sensors in two portable devices. Samples of nasal secretions were obtained from 50 red-motley Holstein calves aged 14-42 days. Calves were subjected to rectal temperature measurements, clinical score according to the Wisconsin respiratory scoring chart, thoracic auscultation, and radiography (Carestream DR, New York, USA). Of the 50 calves, we included samples from 40 (20 "healthy" and 20 "sick") in the training sample. The remaining ten calves (five "healthy" and five "sick") were included in the test sample. It was possible to divide calves into "healthy" and "sick" gr
