U.S. hog operations have become increasingly specialized
The traditional approach of farrow-to-finish hog production in the U.S.—where breeding and gestation, farrowing, nursery, and finishing to market weight are performed on one operation—is being replaced by operations that specialize in a single production phase. In 1992, more than 50 percent of U.S. hog operations used the farrow-to-finish approach. By 2009, less than 25 percent were farrow-to-finish producers. In contrast, hog operations specializing in raising feeder pigs weighing 30-80 pounds to market weights of 225-300 pounds (feeder-to-finish) accounted for less than 20 percent of hog producers in 1992, but nearly 50 percent in 2009. Specialized operations produced more than 70 percent of U.S. finished hog output in 2009, and were more likely to be producing hogs under contract than were farrow-to-finish farms.
