Abstract: Milk samples of a wild female giant panda were collected from all the 4 nipples at 77 days postpartum in the Qinling Mountain area. At this lactation stage the giant panda milk averaged(32.0±2.1)% dry matter, (18.4±2.1)% fat, (8.34±0.16)% crude protein, (2.7±0.12)% sugar, and in two samples (7.6±0.6) kJ/g gross energy. The fat concentrations were very variable, with particularly high fat(25.9%) in milk from the nipple just suckled; the remaining nipples yielded milk containing 14.5%-19.3% fat. Protein accounts for about 22% of the energy in giant panda milk, which is higher than that of the American Black Bear(Ursus americanus)milk at the same lactation stage. This difference may due to the different selective pressure these two species faced during evolution.
