Composition
Donkey milk, along with mare’s milk, is the closest to breast milk, with notably low lipid ratios and high lactose ratios.

Donkey milk is similar to mare milk and human breast milk in that it is relatively poor in protein and fat but rich in lactose. The casein to whey protein ratio is intermediate between human breast milk and cow milk. Gross composition of milk differs by the mother's lactation stage, with ash and protein content showing a declining trend, but pH, percentage of whey protein, and amino acid content remaining the same.

Famous quotes containing the word composition:
“If I don’t write to empty my mind, I go mad. As to that regular, uninterrupted love of writing ... I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.”
—George Gordon Noel Byron (1788–1824)
“Every thing in his composition was little; and he had all the weaknesses of a little mind, without any of the virtues, or even the vices, of a great one.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nor diminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.”
—David Hume (1711–1776)
