• Wild pigs and cattle have 50.3% dietary overlap. • It takes 17.7 wild pigs to equal 1 Animal Unit. • Producers can use this data for management decisions. • Study calculated lost market value of beef steers. Background and objectives : Wild pigs ( Sus scrofa ) are notorious to cattle producers in the United States as causing extensive rooting damage to rangeland, transmitting livestock diseases, and preying on domestic calves. Additionally, while wild pigs are known to consume pasture/rangeland forage, the direct impact of that behavior on commercial cattle productivity remains unquantified. This study aimed to calculate wild pig Animal Unit (AU) equivalents, enabling domestic cattle producers to evaluate competition risk of wild pigs for grazing forage resources on their lands. Data collection : Biomass data (in lbs.) for this calculation was drawn from a dataset of 12,257 wild pigs harvested during control efforts at the Savannah River Site (SRS) in South Carolina. Research methods : After reviewing seven studies on wild pig diets in the U.S., a dietary overlap was calculated to determine the percentage of food wild pigs and cattle both consume. We then calculated AU equivalents for wild pigs using two approaches: population size and density. The projected lost market value for beef steers on various sized properties was also calculated. Results : We estimated the average dietary overlap of forage resources between wild pigs and domestic cattle at 50.3%. We determined that 1,498 lbs. of wild pig biomass equal 1 AU, which amounts to 17.7 wild pigs per one AU. Contributions : Using our estimated wild pig AUs equivalents for specific rangeland, producers can make informed management decisions about controlling these invasive competitors. Such decisions will largely depend on property size and local wild pig population density.
