Method for determining the quality of a semen of a vertebrate animal
First Claim
1. A method for determining the quality of a semen of a vertebrate animal, the method comprising:
- measuring at least one absorption spectrum of a sample of said semen with a spectrometer;
selecting a number n, with n≥
4, of wave numbers σ
j (j∈
[1;
n]) where the wave numbers are spatial frequencies in the spectrum characteristic of semen of a breed or of species of said animal;
determining from said at least one absorption spectrum of at least one of a value of the absorption Xj or a value of the second derivative of the absorption Xj″
(j∈
[1;
n])for each of said n wave numbers σ
j (j∈
[1;
n]); and
calculating a non-return rate Y at a predefined number of days from at least one of said absorption values Xj or the second derivative of the absorption Xj″
previously determined.

Abstract
A method is provided for determining quality of semen of a vertebrate animal. The method includes the following steps: measuring at least one absorption spectrum of a sample of the semen; selecting a number n of wave numbers σj (j∈[1;n]) which are characteristic of the semen of the breed or of the species of the animal; determining from the absorption spectrum or spectra of a value of the absorption Xj and/or a value of the second derivative of the absorption Xj″(j∈[1;n]) for each of the n wave numbers σj (j∈[1;n]); and calculating a non-return rate Y at a predefined number of days from the absorption values Xj and/or from the second derivative of the absorption Xj″ previously determined.
