Milk is considered an equilibrate and complete aliment the reason being its richness in manynutritional elements (proteins, lipids, mineral salts, lactosesand vitamins), to evaluate theparticularities and characteristics of the milk of two species (cow and sheep), the objectives of thisstudy centers around these points : the appreciation of the hygienic qualities of the different rawmilks (cow and sheep) and the estimation of the microbial flora at the experimental farm at theuniversity of Mostaganem.The physico-chemical analyzes carried out focused on the pH, density, fat and dry matter on the onehand, and on the other hand the microbiological analyzes (the search for: FTAM, total and fecalcoliforms, staphylococcus aureus, clostridium sulfite-reducing agent, lactic acid bacteria, yeasts andmolds). this research had been carried out in the period of May - June 2021. the results of the studyshowed that the two types of milk (cow and sheep) are of hygienically acceptable quality with someproliferation of fermentation microorganisms, without pathogenic risks. Microbial loads of FTAMthat do not exceed the standards required by the Algerian official journal, and the absence of fecalcoliforms indicate good microbiological quality of the samples. And for the physicochemicalparameter show a titratable acidity higher than the standards estimated at averages (16.63; 16.50 ° D)for the samples (cow and sheep) respectively, on the other hand a good physicochemical quality isnoted for all the other criteria. studied, a density with respective means of (1.030; 1.036). From anutritional standpoint, the figures have shown that sheep's milk represents the greater load than cow'smilk. However, the lipid fraction represents a fat value (29.53 g / l), the total dry extract (156.68 g /l).
