A method for diagnosing mastitis of cows, includes the steps of (1) irradiating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine, raw milk or a mammary gland of a cow, (2) detecting an intensity of transmitted light rays, reflected light rays or transmit
A method for diagnosing mastitis of cows, includes the steps of (1) irradiating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine, raw milk or a mammary gland of a cow, (2) detecting an intensity of transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland, and (3) effecting multivariate analysis while using a classification model based on probability, separability or similarity, and (4) diagnosing the presence of the mastitis of the cow.

1. A method for diagnosing whether a cow which is unknown to suffer from mastitis (hereinafter referred to as “unknown cow”) suffers from mastitis or not, comprising the steps of:(a) irradiating visible light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into u
1. A method for diagnosing whether a cow which is unknown to suffer from mastitis (hereinafter referred to as “unknown cow”) suffers from mastitis or not, comprising the steps of:(a) irradiating visible light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine, raw milk or a mammary gland of each of known healthy cows and known mastitic cows, detecting intensities of transmitted light rays, reflected light rays or transmitted and/or reflected light rays from said urine, raw milk or mammary gland, effecting a multivariate analysis of the spectral data consisting of wavelengths and detected intensities of the light rays by a principal component analysis, and preparing a SIMCA classification model for each of the known healthy cow group and the known mastitic cow group;(b) irradiating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine, raw milk or a mammary gland of said unknown cow, and detecting intensities of transmitted light rays, reflected light rays and/or transmitted and reflected light rays from said urine, raw milk or mammary gland; and(c) determining whether the unknown cow fits better in either the SIMCA classification model for the healthy cow group or that for the mastic cow group based on probability, separability or similarity, to thereby diagnose whether the unknown cow suffers from mastitis or not. 2. A method for diagnosing mastitis of cows set forth in claim 1, wherein the urine, raw milk or a mammary gland is irradiated with near infrared rays in a wavelength range of 700 nm to 2500 nm. 3. A method for diagnosing mastitis of cows, set forth in claim 1 wherein the urine, raw milk or a mammary gland is irradiated with near infrared rays in a wavelength range of 700 nm to 1100 nm or 1100 nm to 2500 nm. 4. The cow mastitis-diagnosing method set forth in any of claims 1 , 2 and 3 wherein wavelengths of incident rays, transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland are scanned, and wherein the multivariate analysis is applied to the thus obtained spectra of the visual light rays and/or the near infrared rays by using the classification model based on the probability, separability or similarity. 5. An apparatus for performing the method claimed in claim 1 for diagnosing whether a cow which is unknown to suffer from mastitis (hereinafter referred to as “unknown cow”) suffers from mastitis or not, comprising:an electromagnetic ray generator for generating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm;an optical system for introducing the visual light rays and/or near infrared rays into urine, raw milk or a mammary gland of a cow;a detector for detecting an intensity of transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland; anda data processor for receiving signals from said detector, effecting a principal component analysis of spectral data of the transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland, effecting a multivariate analysis of the spectral data consisting of wavelengths and detected intensities of the light rays by a principal component analysis, and preparing a SIMCA classification model for each of the known healthy cow group and the known mastitic cow group based on probability, separability or similarity, deciding which unknown cow fits better to either the SIMCA classification model for the healthy cow group or that for the mastitic cow group based on probability, separability or similarity, and judging that the unknown cow belongs to the cow group to which the unknown cow fits better. 6. The cow mastitis-diagnosing apparatus set forth in claim 5, wherein said electromagnetic ray generator is an infrared ray generator for generating near infrared rays in a wavelength range of 700 to 2500 nm, an infrared ray generator for generating near infrared rays in a wavelength range of 700 to 1100 nm, or an infrared ray generator for generating near infrared rays in a wavelength range of 1100 to 2500 nm. 7. The cow mastitis-diagnosing apparatus set forth in claim 5 or 6 which further comprises an optical fiber from said electromagnetic ray generator for introducing the visual light rays and/or near infrared rays into said urine, raw milk or a mammary gland of the cow, and transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland is led to said detector through the optical fiber. 8. The cow mastitis-diagnosing apparatus set forth in claim 7, which further comprises a feeder for introducing said raw milk into a sample container via an on-line or at line. 9. The cow mastitis-diagnosing apparatus set forth in claim 8, which further comprises a sample container for holding the raw milk, and a temperature controller for stabilizing the milk inside the sample container to a given temperature. 10. The cow mastitis-diagnosing apparatus set forth in claim 7, which further comprises a sample container for holding the raw milk, and a temperature controller for stabilizing the milk inside the sample container to a given temperature. 11. The cow mastitis-diagnosing apparatus set forth in claim 5 or 6, which further comprises a feeder for introducing said raw milk into a sample container via an on-line or at line. 12. The cow mastitis-diagnosing apparatus set forth in claim 11, which further comprises a sample container for holding the raw milk, and a temperature controller for stabilizing the milk inside the sample container to a given temperature. 13. The cow mastitis-diagnosing apparatus set forth in claim 5 or 6, which further comprises a sample container for holding the raw milk, and a temperature controller for stabilizing the milk inside the sample container to a given temperature.
