Abstract

Our work is geared towards analyzing the quality of the milk we consume daily. This study concerns the analysis of the physico-chemical and microbiological quality of raw milk from 3 different breeds of dairy cows: local, crossed and imported in the region of Tlemcen. The results obtained after physicochemical and microbiological analyzes of the raw milk of the three breeds prove that there are variations in their physico-chemical quality essentially the fat; the milk of the imported breed is the richest followed by the cross breed and lastly the local breed. For microbiological quality it has been found that raw milk of the imported breed contains a significant microbial load, it is above the national and international hygiene standards compared to the raw milk of the local cross breed which are the norm.
