A USDA survey was mailed to 18,000 producers in 13 states, where the largest feral hog populations are found, to better understand the impact of feral hog damage to operations, the agency said. Damage is commonly reported to pasture grasses, various plant species and through promotion of weed growth. The results of the survey are nearing final stages with the ultimate goal of securing additional funds from Congress to control the problem. Producers still have until Aug. 18 to complete the survey online. Find out more.
