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 regression analysis, 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: irradiating visible light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine or a mamma
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: irradiating visible light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine 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 reflected light rays from said urine or mammary gland, determining the number of somatic cells for each of said known healthy and mastitic cows, and building up a model enabling an inverse calculation of the numbers of the somatic cells in the raw milk from the near infrared spectra by a multivariate regression analysis by using said detected intensities of the light rays and said detected numbers of the somatic cells; irradiating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine or a mammary gland of said unknown cow, detecting intensities of transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine or mammary gland; determining the number of the somatic cells for an unknown cow based on said detected intensities of the light rays for the unknown cow and said inverse calculation model; and determining whether the unknown cow suffers from mastitis or not, based on the determined number of the somatic cells. 2. A method for diagnosing mastitis of cows set forth in claim 1, wherein the urine or 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 or 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 and3, wherein wavelengths of incident rays, transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine or mammary gland are scanned, and wherein the multivariate regression analysis is applied to the thus obtained spectrum of the visual light rays and/or the near infrared rays.5. The cow mastitis-diagnosing method set forth in claim 4, wherein the multivariate regression analysis is effected by multilinear regression (MLR), principal component regression (PCR) or partial least square regression (PLS).6. The cow mastitis-diagnosing method set forth in any of claims 1,2 and3, wherein the multivariate regression analysis is effected by multilinear regression (MLR), principal component regression (PCR) or partial least square regression (PLS).7. 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 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 or mammary gland; and a data processor which receives signals from said detector, and which builds and stores the model enabling the inverse calculation of the numbers of the somatic cells in the raw milk from the light spectra by the multivariate regression analysis by using said detected intensities of the light rays and said detected numbers of somatic cells. 8. The cow mastitis-diagnosing apparatus set forth in claim 7, 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 ran ge of 700 to 1100 nm, or an infrared ray generator for generating near infrared rays in a wavelength range of 1100 to 2500 nm.9. The cow mastitis-diagnosing apparatus set forth in claim 7 or8, 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 or a mammary gland of the cow, and transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, or mammary gland is led to said detector through the optical fiber.10. The cow mastitis-diagnosing apparatus set forth in claim 9, wherein the multivariate regression analysis is effected by multilinear regression (MLR), principal component regression (PCR) or partial least square regression (PLS).11. The cow mastitis-diagnosing apparatus set forth in claim 7 or8 wherein the multivariate regression analysis is effected by multilinear regression (MLR), principal component regression (PCP) or partial least square regression (PLS).
