Abstract

An apparatus for detecting the reproductive status, in particular the oestrus cycle, of a mammal, comprising detecting means (10) to detect a blood amount perfused in a predetermined region of the vagina canal of a mammal, and generating a corresponding main signal (20); the apparatus (1) further comprises a processing unit (40) associated with said detecting means (10) to determine the reproductive status of said mammal depending on said main signal (20). Also disclosed is a method of detecting the reproductive status, in particular the oestrus cycle, of a mammal.

Claims

1. A method of detecting a reproductive status of a non-human animal which undergoes oestrus, said method comprising the following steps:

detecting a blood amount perfused in a predetermined region of a vaginal canal of said animal by;

illuminating said predetermined region with a first electromagnetic radiation having a first wavelength between 760 nm and 1400 nm, a second electromagnetic radiation having a second wavelength between 600 nm and 760 nm, and a third electromagnetic radiation having a third wavelength between 490 nm and 600 nm,

receiving a reflected radiation of each of said first, second and third radiations from said region,

obtaining values for each of said reflected radiations,

comparing using a processing unit said values for each of said reflected radiations with each other and comparing, using said processing unit, said values from said first, second, and third wavelengths with, respectively, values predetermined from reflected radiations of said first, second, and third wavelengths, the predetermined values being typical of said animal'"'"'s vulva during an oestrus period; and

determining using a processing unit a reproductive status of said animal depending on said comparisons.

2. A method as claimed in claim 1, further comprising a step of inserting detecting means into said animal'"'"'s vaginal canal for detecting said blood amount.

3. A method as claimed in claim 1, wherein said first and second electromagnetic radiations are generated in different time intervals.

4. A method according to claim 1, wherein the comparison step between the radiation emissions or components at different wavelengths includes calculating ratios between the intensities of said reflected radiations.

5. A method according to claim 2, wherein the first wavelength is representative of vaginal redness of the region of the vaginal canal, and the second and the third wavelengths are used to determine whether the variations of intensities of the first wavelength correspond to variations of said vaginal redness or mere movements of the detecting means.
