Feral Hog

  • Feral hogs (Sus scrofa) are present in all 64 parishes in Louisiana. Louisiana’s population is estimated at 700,000.
  • Gestation is 114 days and feral sows can have 2 litters per year averaging 6 piglets per litter. Statisticians have determined that 75 percent of the population must be harvested to maintain a static population.
  • Feral hogs are omnivores and can adapt to nearly any environment from desert to marsh to piney woods and hardwoods and can even survive in sub-arctic conditions.
  • Feral hogs impact wildlife by direct competition for hard mast resources and by predation on reptiles, amphibians, ground-nesting bird eggs and mammals including deer fawns.
  • Feral hogs uproot both planted and naturally regenerated coniferous and hardwood seedlings. Additionally, their heavy consumption of hard mast significantly reduces natural forest regeneration.
  • They increase erosion and shed coliform bacteria into waterways.
  • Feral hogs heavily impact agriculture, uprooting planted seeds, destroying mature crops and uprooting hayfields making hay cutting difficult to impossible. • LDWF surveillance testing of over 1,000 feral swine statewide revealed that 5 percent were serologically positive to Brucella antigen (Swine Brucellosis).
  • Other diseases found in feral hogs include Pseudorabies, Leptospira, and Trichinosis .
  • Hog control methods now currently used in Louisiana include recreational hunting and trapping by private landowners, daylight and night time shooting and aerial gunning via helicopter.
  • Possible hog control methods being researched including toxicants such as sodium nitrite and genetically-based contraception.
