Livestock in 2001 included some 14,000 head of cattle, 32,000 pigs, and 4,000 goats. Pigs, traditionally kept by many households for ceremonial purposes, are being upgraded through the introduction of improved strains. Two pig farms operate on Pohnpei. The largest cattle herd is on Pohnpei Island. Eggs are produced commercially, and limited success has been achieved by commercial poultry chicken projects in the states of Pohnpei and Chuuk. Chickens are kept by many households. Goat projects are also operating in Kosrae and Chuuk. A few head of water buffalo are privately raised on Pohnpei and on Pata in Chuuk. In the mid-1990s, the government started encouraging domestic feed production in order to decrease the reliance on imported feed meal.
