Summary

The principle of Transmittance (T) is proposed for a test to detect mastitis cow side with the aid of a portable electronic device, called Milktester RMM. Transmittance value depends on the concentration, color and homogeneity of a sample, crossed through by a beam of monochromatic electromagnetic radiation. Milktester RMM is o prototype designed to detect and quantify modifications of homogeneity and color which characterizes an abnormal milk, in accordance with the current Regulation (EC) No 853/2004 of the European Parliament. The proposed optical device is able to measure, calculate and display, in a few seconds, the transmittance coefficient of intensity (TCI) and deviation coefficient (DC) which, in their turn, is influenced by at least three kinds of alterations: concentration in different substances, color and turbidity. Every reading for every quarter is taken into account and calculates by comparison to the average value of the other two quarters, belonging to the same animal, considered normal, healthy and taken as reference.

Key words: abnormal milk, milk tester, mastitis detection (more…)
