1. A method for evaluating spectra of a biological substance of animal and/or vegetable origin, the method comprising:
(a) detecting a spectrometer in a network formed of at least one spectrometer and an input/output device;
(b) requesting an individual status of each spectrometer in the network of the detecting (a), and displaying the detected spectrometers and their status on the input/output device, wherein the status reflects if a spectrometer is available for recording a spectrum or not;
(c) receiving a selection from the spectrometers being available for recording a spectrum on the input/output device;
(d) recording a spectrum of a sample material of animal origin, vegetable origin or a mixture thereof on the spectrometer selected in the receiving (c), wherein the recording (d) further comprises (dl) predicting the identity of the sample material of the recording (d) from the spectrum recorded in the recording (d) by a similarity analysis using a database DB1 of spectra of known materials; (d2a) displaying a predicted identity of the sample material obtained in the predicting (dl) on the input/output device; and (d2b) receiving (i) a confirmation of the predicted identity displayed in the displaying (d2a) or (ii) a non-confirmation of the predicted identify displayed in the displaying (d2a) and the input of the identity of the sample material on the input/output device;
(e) predicting a value for at least one parameter from the spectrum of the recording (d) by at least one calibration function and/or calibration graph suitable for predicting the value of the at least one parameter, the at least one parameter being (1) content of at least one amino acid, (2) crude protein content, (3) ammonia content, (4) total amino acid and ammonia content, (5) total amino acid content without ammonia, (6) crude fat content, (7) dry matter content, (8) crude ash content, (9) energy content, (10) biogenic amine content, (11) antinutritional factor content, antinutritional factor(s) being a trypsin inhibitor, a glucosinolate, a gossypol, and/or any derivative and/or salts thereof, (11) sugar content, (12) starch content, (13) crude fiber content, (14) neutral detergent fiber content, (15) acid detergent fiber content, (16) total phosphorous content, (17) phytate phosphorous content, (18) reactive lysine content, (19) total lysine content, (20) reactive lysine content to total lysine content ratio, (21) protein dispersibility index, (21) protein solubility, (22) trypsin inhibitor activity, (23) urease activity, and (24) proceeding conditions indicator (PCI); and
(f) displaying a result from the prediction (e) on the input/output device.
