A nasal breath sampling device was developed for use with dairy cattle. This device was tested as a means of supplying breath for analysis by a gas sensor array, gas chromatograph-mass spectrometer, and Fourier transform infrared spectrophotometer. Concentrations of methane, dimethyl sulphide, butan-2-one, and propanone (acetone) in cow nasal breath, under field conditions, are reported for the first time, and were detected at 70-1000 p.p.m., 80-100 p.p.m., 70-80 p.p.m., and 1-10 p.p.m., respectively. The output from a six-element gas sensor array was analysed using chemometric techniques. Breath samples were successfully classified in terms of known input odours by referencing to serum 3-hydroxybutanoate (beta-HB) concentrations. These preliminary breath odour sensing studies suggest that it may be possible to discriminate between healthy cows and cows with ketosis by developing an application-specific electronic nose (ASEN) and sampler.
