Abstract

In order to study the race effect on the physico-chemical characteristics and protein profile, two sheep or ovine breeds Hamra and Ouled Djellal were raised in the same condition sat the ITELV (National institute of breeding) (Ain Hajar-Saida, Algeria). The analyses were focused on the pH, density, freezing, fat, total protein, dry defatted extract and total dry extract. The results obtained or these parameters showed no significant differences between the two races. Then the protein fractions were isolated and analyzed by Poly Acryl Amide Gel Electrophoresis (PAGE) under different conditions (native and in presence of urea). The resulting electrophoretic profiles have identified similarities between the two breeds milk.
