Milk

Milk Bottles (DW: The Stolen Earth)

Milk was a substance secreted by mammals to feed their young.

Milk-producing species

Whether the female of a species exuded milk from its nipples or from simple ducts to nurture its young was one of the defining traits of mammals. (EDA: The Year of Intelligent Tigers) Similar nourishing substances were produced by non-mammalian species. Malmooth could drink their own internal milk, (DW: Utopia) while the green milk produced by Skarasens was fed on by the Zygons. (NSA: Sting of the Zygons, EDA: The Bodysnatchers)

The only known cure for spectrox toxaemia was the milk from a Queen Spectrox Bat. (DW: The Caves of Androzani)

The seemingly male Sontarans could be genespliced to produce milk. (DW: A Good Man Goes to War)

Milk as a beverage

Milk was also used by other species as a drink. The humans of Earth harvested and drank the milk of cows.

Milk was often used in tea and coffee to add taste. (NA: Theatre of War) Milk wase sold in cartons or glass bottles, and delivered by milkmen. (DW: The Stolen Earth) It was sometimes drunk warm as a sleep aid. (DW: Invasion of the Dinosaurs)

In some locations, such as the planet Sto, milk was sold in a Milk Market. (DW: Voyage of the Damned)
