| Rapid change in the size and ownership structure of U.S. hog production has created new and varied challenges for the industry. This report describes an industry becoming increasingly concentrated among fewer and larger farms, and becoming more economically efficient. These changes have not come without problems. The increasing market control and power concentrated among packers and large hog operations, and the manure management problem posed by an increasing concentration of hog manure on fewer operations, are paramount concerns. Addressing these concerns through regulations would likely impose economic costs that could be passed on to consumers. In addition, the relative mobility of the hog industry means that regulations could result in significant... |

| Over the last twenty five years commodity crop farms have steadily declined in number and grown in average size, and production has shifted to larger operations. During the same period, the share of agricultural payments going to large farms has increased, in large part because payments are tied to actual or historical crop production. This study evaluates whether payments from federal farm programs may have contributed to the concentration of farmland. Using zip code-level data constructed from the micro files of the 1987-2002 Agriculture Censuses the study estimates the association between government payments per acre and subsequent growth in weighted median farmland area. A semi-parametric generalized additive model controls for location and initial... |

| Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study describes the extent to which antibiotics are used in hog production and how this changed between 2004 and 2009. This study also uses a sample-selection model to examine the impact that use has on the productivity of U.S. hog operations. Using hog producer data from 2004, the analysis did not find a relationship between productivity and sub-therapeutic antibiotics fed during finishing, but productivity was significantly improved when fed to nursery pigs. These results are being evaluated... |

| Economic theory suggests several possible mechanisms through which direct government farm payments might influence the pattern of structural change in agriculture. This study estimates what effect farm payments have had on farm structure using farm-level panel data from the 1987, 1992, and 1997 Agricultural Censuses. Results suggest that the size of per-acre payments received in the past are associated with a small and weakly positive change in farm size between consecutive censuses, but that payments are significantly correlated with an increased likelihood of farm survival between consecutive periods. |

| In recent years, structural changes in the hog sector, including increasing farm size and regional shifts in production, have altered manure management practices. Over the same period, changes to the Clean Water Act, new state regulations, and increasing local conflicts over odor have influenced manure management decisions. This study uses data from two national surveys of hog farmers to examine how hog manure management practices vary with the scale of production and how these practices evolved between 1998 and 2004. The findings provide insights into the effects of structural changes and recent policies on manure management technologies and practices, the use of nutrient management plans, and manure application rates. |

| Hog production in 2004 was characterized by wide variation in the types, sizes, and economic performance of operations. Operations specializing in a single production phase generated more than three times the product value, on average, of those using the traditional farrow-to-finish approach. Low-cost operations tended to be larger, located in the Heartland, and operated by farmers whose primary occupation was farming. Small and medium operations far outnumbered large and very large operations, but large and very large operations accounted for most of the production. Average production costs declined as the size of the hog operation increased, a result of reduced capital costs and more efficient input use. Hog production was highly concentrated in the... |
