Comparison between Holstein cow's milk and Japanese-Saanen goat's milk in fatty acid composition, lipid digestibility and protein profile

The fatty acid composition, the lipid digestibility and protein profile of Japanese-Saanen goat's milk were characterized. Caprine milk contained substantial quantities of C-4:0 to C-10:0 fatty acids as compared with Holstein cow's milk. The lipids of the former showed significantly higher digestibility in vitro by porcine lipase than those of the latter (P < 0.05). As determined by SDS-PAGE, the respective contents of alpha(s1)-casein, one of the major allergens, were 3.9% and 33.7% in caprine and bovine milk.
