Résumé:
A study of some physicochemical characteristics was undertaken on milk of three animal species (cow, ewe and goat) and of three bovine races (Red magpie, black magPie and the Brown of the Atlas) bred in the town of Jijel, and on milk coming from subclinic fungic mastitis. For this purpose, 90 milk samples were analyzed at the laboratory of the physicochemical analysis of the ITELV-Baba Ali and at the laboratory of Parasitology-Mycology of the high national veterinary school of Algiers. The rate of the fat contents and proteins are high in the ewes. There is a small difference between the local cows and the ewes and they are very different at the imported bovine races. In the mastitis milk of the same species or of the same animal race, differences in the content of proteins were noted according to mushroom in question. A significant difference was noted for Candida tropicalis in the local cow and highly significant for all the fungic species in the black Magpie.
