Weights depend on genetic background and food availability. Generally, the wild Big Boars can reach larger weights than females but this is not a hard and fast rule. Average weights vary but run 200 pounds for adult males and 175 pounds for adult females. A 300 pound feral hog is a large wild pig. The unusually large weights of 500-Plus pounds that you hear about occasionally reported in the media are very rare.
Wild pigs are mostly nocturnal and rarely seen in the open during daylight. More readily seen is the damage they cause to farms, lawns and golf courses.- BigDaddy recommends night hunting Feeder-Lights, traps and any other method that works!
Mortality rates vary greatly and impact the very young and the very old primarily. Predation is not a big issue once they reach about 10 to 15 pounds. Hunting can be a significant mortality factor in some regions but generally is not enough to offset population growth. Average lifespan is probably between 4 and 8 years of age according to The Texas A&M AgriLife Extension Service which surveyed landowners in 2011 to determine an estimate of how many wild pigs are removed from the Texas landscape each year.
The wild pig is the most prolific large mammal on the face of the Earth - Sows have approximately 1.5 litters per year. Young females do not typically have their first litter until they are 13+ months of age, even though they can be sexually mature at 6 to 8 months of age or even earlier in some cases.
