Abstract :
This work concerns a statistical study whose objective is to study the variation in non-protein nitrogen content on samples from cow milk collection centers (cooperative collection centers) and farms in the Doukkala region (DKK), Chaouia, Fkih Ben Salh (FBS), El-Kalaa, Meknes and Gharb, and the possibility of eliminating the non-protein nitrogen determination phase to calculate the protein milk. Samples were collected throughout the year 2015. Analysis results show that there is a relationship (factor) between the total nitrogen (NT) and protein nitrogen (NP) parameters and also show that the effect Of the milk origin and the period does not significantly affect non-protein nitrogen (NPN) in milk.
