A milk sample from a captive giant panda (Ailuropoda melanoleuca), obtained at 13 days postpartum, contained 7.1% protein, 1.6% carbohydrate, 10.4% lipid and 0.9% ash. The ratio of casein to whey proteins was 5.0:2.1. Sodium dodecyl sulfate polyacrylamide electrophoresis (SDS-PAGE) of the whey protein fraction showed the presence of at least two major proteins other than α-lactalbumin and β-lactoglobulin. SDS-PAGE and urea-gel electrophoresis showed that αs-casein is not a major component. The proportions of triacylglycerol, cholesterol, cholesterol esters and phospholipid were 90.5, 5.3, 0.96 and 3.1%, of the total lipid, respectively. The dominant saccharide in the panda milk was Gal(α1-3)Gal(β1-4)Glc (isoglobotriose). The milk contained, in addition, lesser amounts of lactose, Gal(α1-3)Gal(β1-4)[Fuc(α1-3)]Glc (fucosyl isoglobotriose), Neu5Ac(α2-3)Gal(β1-4)Glc (3′-N-acetylneuraminyl-lactose), Neu5Ac(α2-6)Gal(β1-4)Glc (6′-N-acetylneuraminyl-lactose) and Neu5Ac(α2-3)Gal(β1-4)[Fuc(α1-3)]Glc.
