When the desert is green (from the middle of March to the end of April), about one-fourth of Kuwait's meat supply is provided locally. The 2001 livestock population included: cattle, 22,000; sheep, 630,000; goats, 130,000; and chickens, 32,463,000. Kuwait's poultry production has recovered from damages inflicted during the 1990 invasion. Production in 2001 was estimated at 42,000 tons, exceeding the previous high of 21,000 tons in 1989. A small number of Bedouins raise camels, goats, and sheep for meat and milk.
