These production adjustments combine with strengthening meat exports to reduce domestic per capita consumption through 2012. The result is lower production at higher prices, which improves net returns and provides economic incentives for moderate expansion in the sector later in the projection period.Pork production declines in 2009-11 in response to high feed prices and lower demand and then grows for the remainder of the projection period as higher hog prices improve returns.
