<p>A method and apparatus for detecting mastitis in a short time with high accuracy by optically counting somatic cells in raw milk or in an udder. The apparatus comprises a light source (1) emitting measurement light, a spectroscope (9) for extracting only a desired wavelength from the light from the light source by dispersing the light, a light chopper (14) disposed between a lens (11) and a reflecting mirror (12), an integrating sphere (13) formed of a light-diffusing member, and a sample holder (40) holding a sample such as raw milk. Near infrared radiation is applied to raw milk or an udder, the intensity of transmitted, reflected, or transmitted/reflected light of predetermined wavelength is measured, and multivariable analysis by the SIMCA method is conducted, thus detecting mastitis from the spectrum of the light from raw milk or an udder.</p> |
