Abstract - The Authors, after predicting that the importance of a research, even if it's indirect, on the biological worth of milk may assume about a better utilisation of it, follow, through a study on the covariance between v and st, the modifications of its bio-colloids. The examination concerns sterilized and analized milk during a whole year of storing, with the programmation of the research by time-observation-groups, bound to some determinated seasonal periods of the suns's year.
The results, marked by the absence of a linear correlation and by the absence of a linearity in the same correlation's absence between v and st, should announce a sommewhat irregular behaviour of the modifications to whose is subjected the milk's colloido-proteic phases with a covariance of values that seams to show itseff through an elicoidal type carriage. This seams to be influenced by the time-seasons's type of the research. Although the high variability, typically irregular, to whom are subjected the milk's bio-colloids, should allow to conclude that the proteic molecular building - to whom is bound, above all, the biological worth of milk - after a year of storing wille lose the typical characters of the rising status
