Goat
From Tardis Wiki, the free Doctor Who reference
A goat was an animal that was a common sight in India. The most-well known breed was the Mountain Goat. Upon landing in 1947 Calcutta, the Tenth Doctor was, perhaps jokingly, worried about scaring the goats. So prevalent were goats in Indian society that it could be troubling if they were absent. Cameron Campbell once travelled in rural India and was disturbed by the fact he couldn't see even one child pulling a goat around by a string.
Like cows, goats also produced milk which humans consumed. (PROSE: Ghosts of India)
Breeds
Mountain goats were amongst the distinctive subspecies known to exist on Earth.
