Feral swine are no exception to this old farmer’s anecdote “Happier than a pig in mud!”

Because they lack sweat glands, wallowing in mud and water is an instinctual behavior necessary for them to maintain a healthy body temperature. Unfortunately, this behavior has cascading impacts, not only to water quality in individual streams, ponds and wetlands, but to entire watersheds and ecosystems.

Excessive feral swine traffic around wallows and water sources causes erosion along stream banks and shorelines. Sounders, or family groups, of feral swine spend large amounts of their day around the wallow, especially in hot weather, which means they leave significant amounts of urine and feces in and around the water. The impacts to water quality go far beyond the immediate wallow site when silt, excrement and potentially harmful pathogens, are washed down stream.

Water polluted from feral swine wallowing can be contaminated with parasites and bacteria such as giardia, salmonella and pathogenic E. coli that could be transmitted to humans and other animals. This can happen when feral swine use an agricultural water source, such as an irrigation pond, or if feral swine are active in an area people use for recreation. Contamination can even occur if feral swine use a site upstream in the watershed and rain runoff carries contaminates downstream. In many watersheds, feral swine damage to water quality, wetlands and riparian habitats also threatens native wildlife, including threatened and endangered species, which depend on these ecosystems.

The pathogens transmitted by feral swine can sicken livestock, pets and people. Livestock and pets may become ill by drinking water from streams or ponds contaminated by feral swine. Humans are at risk when swimming or wading in contaminated water, from eating crops in which feral swine have rooted or defecated, or if feral swine have contaminated the irrigation source for the crops. Feral swine are suspected to have played a role in the contamination of surface water and spinach fields in California, causing a food-borne illness outbreak which sickened 205 people and resulted in three deaths.

No matter the water source, feral swine will muddy it. The USDA’s Animal and Plant Health Inspection Service National Feral Swine Damage Management Program has been appropriated $20 million annually to address the management of damage caused by invasive feral swine. The program’s overall goal in the United States and its territories, is to protect agriculture, natural resources, property, animal health, and human health and safety by managing damage caused by feral swine and, where possible, reducing or eliminating feral swine populations. The program works in cooperation with states, tribes and other federal and international agencies, universities, and other stakeholders to achieve management goals.



Everything you want to know about beef. All in one place. From live cattle working to tractor equipment and Brush Buster’s demonstrations, ranchers will get an in-depth look at the beef industry during the 62nd annual Texas A&M Beef Cattle Short Course slated for Aug. 1-3 at Texas A&M University in College Station.

Additional topics will include beef cattle business management, carcass value determination and an industry trade show.“The live cattle handling demonstration will give participants the chance to see proper low-stress cattle penning techniques, working facility design and proper calf processing techniques,” said Dr. Jason Cleere, Extension beef cattle specialist in College Station and conference coordinator.

The short course is the premier beef educational event in the Lone Star State, attracting more than 1,400 attendees annually, according to Cleere.

The program will feature 20 sessions to provide participants with an opportunity to choose workshops based on their level of production experience and needs of their ranch.

“Concurrent workshops will feature information on introductory cattle production, forage management practices, range management, nutrition and reproduction, record keeping, genetics, purebred cattle and much more,” he said.

All demonstrations will be held Aug. 3 at various locations, according to AgriLife Today.

Participants can earn at least seven Texas Department of Agriculture pesticide continuing education units if they are already licensed.

“The goal of the short course each year is to provide sessions on basic beef cattle production practices, as well as the most cutting-edge information needed by beef cattle producers,” Cleere said. “We think we have information for everyone to take home and apply to their operations.”

Registration is $180 per person before July 25 or $220 afterwards. The registration fee includes educational materials, a copy of the Beef Cattle Short Course proceedings, trade show admittance and admissions to the prime rib dinner, lunches, breakfasts and daily refreshments.
