Measures are needed to address the three main factors that contribute to gastric ulcers in hogs: feed/nutrition, stress and health challenges.  |  File photo

Multipronged strategy can prevent gastric ulcers in hogs

Gastric ulcers are commonly found in pigs. Severe cases causing death account for one to two per cent of finisher farm mortality. These ulcers, also known as stomach ulcers, are not a new phenomenon, first being reported in swine literature as early as 1897. However, the recent prevalence of mild to moderate cases showing some […] Read more


Most swine flu strains in North America have genome segments that were acquired from human strains, because flu viruses have a segmented genome that allows one virus to trade segments of its genome with another strain.  |  File photo

Managing influenza in pigs is a frustrating task

Influenza has had a lot of attention over the past several months with a highly pathogenic avian flu strain causing health challenges in dairy herds in the United States. While there have been other cattle influenza infections over the years, this is perhaps one of the more significant birds-to-bovine events. In this article, we will […] Read more

New and emerging swine diseases deserve close watch

Veterinarians are taught that when we hear hoofbeats, think of horses, not zebras. This is sage advice to help maintain a diagnostic process based on probabilities. If I come across a nursery pig that has died suddenly with organs that have tiny hemorrhages and slightly enlarged lymph nodes, I will request tests to confirm a […] Read more


Hog farms that concentrate breeding activities to allow for larger groups to be bred at the same time, farrow at the same time and subsequently wean at the same time will benefit on many levels.  |  File photo

Batch farrowing is a strategy that can improve hog health

Conventional farm health wisdom focuses on vaccines, antibiotics and other medical interventions. In addition to these hallmarks of pig health management, some farms have gone back to basics in designing pig flow through their operations to improve animal health. Pig flow also affects sustainability of the farm’s human resources, marketing of hogs and profitability. In […] Read more

Strep zoo: bacterium affects pigs in Western Canada

Western Canadian swine farms manage many bacterial challenges by controlling what pig sources are mixed together, reducing environmental and other stressors, good nutrition and control of viral diseases that act as cofactors in many bacterial challenges. A lot of farm bacterial challenges become repeatable, following similar patterns to previous outbreaks or challenges. Fortunately, many common […] Read more

Current research into pelvic organ prolapses in sows has still not provided the hog industry with solutions, but researchers are beginning to understand that there are measurable differences in sows that exhibit varying risk levels of prolapsing.  |  File photo

Getting to the bottom of pelvic organ prolapses in sows

In a previous article, I discussed sow mortality as a significant welfare concern and economic cost to many modern swine operations. Each sow mortality can have upwards of $1,500 in real or opportunity costs associated with it. A 2019 survey of more than 400 sow farms in the United States found that 0.3 to 10.3 […] Read more


Internal biosecurity has always been important on swine farms by preventing movement of the pathogen within the farrowing rooms. | File photo

New vaccine technology helps control diarrhea in piglets

It’s frustrating for veterinarians to try and make a definitive diagnosis of an ongoing health challenge if they lack the tools in the toolbox to help the situation. One such disease of young suckling piglets is Rotaviral enteritis (diarrhea). Rotavirus: the organism While there are many devastating viral diarrheas on western Canadian pig farms, Rotavirus […] Read more
