US had lesser hog farms in 2017 than 1997, biggest farms raised most of country's pigs, USDA report states


In the space of a generation, US hog production has transformed, even if the Midwest, with Iowa foremost, is still the leader, said a new report by the United States Department of Agriculture (USDA).


There were half as many hog farms in the United States in 2017 as there were in 1997, and the largest farms, often specialised operations, raised 93% of the pigs.


"The shift to specialised operations occurred along with two other developments: The movement to widespread use of production contracts and the emergence of larger operations," said the report, written by seven USDA economists. "By capturing economies of scale, large hog operations have become more efficient than smaller ones."


The largest farms, with more than 2,000 head, held 61% of US hogs in 1997. Their share grew to 91% in 2017, although they were one-eighth of the 66,439 hogs farms in the US.


Traditionally, hogs were raised on the same farm from birth until they were ready for slaughter. Such farrow-to-finish operations accounted for 54% of hog farms and 65% of hog production in 1992. They have been displaced by feeder-to-finish operations, which specialise in the final stage of fattening market hogs for slaughter.


"By 2015, 60% of hogs farms were feeder-to-finish operations, producing 83% of all hogs," said the USDA.


Hog production was concentrated in the Midwest for most of the 20th century, and USDA's latest Hogs and Pigs report said the region is home to two-thirds of all hogs. Iowa is the number one hog state, producing nearly one-third of the total.


Minnesota is number two with 12%. Since the 1990s, production expanded in the Southeast and North Carolina is the number three state, with 11%.


"Familiarity with poultry contract production in the Southern Seaboard Region likely contributed to the acceptance of contracts for hog production in North Carolina," said the report.


All but a few hog farmers were independent operators in 1992. By 2015, 53% of farms raised hogs under contract and they produced 69% of the hogs. Production contracts were dominant in North Carolina, accounting for 91% of its hogs sold in 2017.


Iowa and Minnesota were split between independent and contract production.


Hogs reach slaughter weight about six months after birth. The US pig herd has grown in number by 18% since 1997, and market hogs weighed an additional 33 pounds per head in 2017.


"Those two factors — more hogs and larger hogs — contributed to an increased supply of US pork," said the USDA. Hog sales or removals per farm averaged 945 in 1997 and were nine times larger, 8,721 head, in 2015.


Per capita consumption of pork has been stable, so exports have become an important market. Nearly a quarter of the estimated 27.1 billion pounds of pork produced this year will be sold overseas.


"The hog sector began a major transformation in the early 1990s and since then has experienced productivity growth, structural change, increased output and expanded exports," said the USDA. "From a broad perspective, the number of hog farms declined over time, the typical farm became larger and the regional pattern of production shifted."
