All eyes are on feral pigs

Large numbers of feral pigs continue to be a problem in North America – and that by itself is already a problem, but concerns go deeper… Though African swine fever (ASF) isn’t currently present in that part of the continent, wild boars are an established vector in Europe. So, should the disease enter the country, it would be a major issue for the industry and for national security.

• The issue was discussed at the Transboundary Feral Swine Summit, a US-Canada meeting held recently, and it was noted that progress is being made to control and eradicate various wild pig populations through multiple initiatives in different Canadian provinces, including cooperation with U.S. professionals.
• In the US, feral pigs are now found across most states and control has been attempted through fencing, snare traps, cage traps, and hunting – all of which have had little effect. The exception is HogStop.

HogStop causes changes to sperm, thus affecting male fertility and preventing the proliferation of feral pigs. The product must be given continually to sustain its effect, though, and should also only be added to hog-specific feeders designed to keep out all other species.

• So far, it’s been working like a charm, but further studies are needed before it can be used in more states.
