Identification of Goats’ and Cows’ Milk Protein Profile in Banyumas Regency by Sodium Dedocyl Sulphate Gel Electrophoresis (Sds-Page)

Protein is one of the nutrient components in milk that related to product quality. The protein are divided into casein alpha-s1, beta, alpha-s2, kappa, and whey fractions such as alpha lactalbumin beta lactoglobulin. There no existing data fraction dairy cow goats Banyumas Regency. This study aimed determine profile form goat Banyumas. Milk sample from fifty cows thirty was taken by random sampling some areas. identified technique sodium dodecyl sulphate gel electrophoresis (SDS-PAGE) quantity prediction software. obtained were analyzed statistically Mann-Whitney between goats. results significantly different (p<0.05) molecular weight alpha-S1 (29.66 vs 33.37 kDa), alpha-S2 (27.76 29.49 (24 , 48 25.59 kDa) lactoglobulin (15.75 15.97 kDa). (7.88 4.16 g/l), (1.31 vs. 4.02 (8.74 14.24 kappa (2.41 4.28 g/l) (0.91 0.7 g / l) (p <0.05) cow's goat's milk, respectively. In conclusion, Regency different.
