<p>A method and apparatus for detecting mastitis in a short time with high accuracy by optically counting somatic cells in urine, raw milk, or an udder of a cow. 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. Visible light or near infrared radiation is applied to urine, raw milk, or an udder of a cow, the intensity of transmitted, reflected, or transmitted/reflected light of predetermined wavelength is measured, and multivariable regression analysis is conducted, thus detecting mastitis from the spectrum of the light from raw milk or an udder.</p> |
