S. suis infection in weaned pigs can result in heart valve infections that cause lesions, which vets often call “cauliflower heart,” seen here in the middle of the photo. Blood backs up into the lungs, resulting in congestive heart failure.  |  Western College of Veterinary Medicine/Dr. Ted Clark photo

Streptococcus suis is common and deadly on hog farms

Many health challenges come and go within pig populations. Recently we have had a lot of porcine epidemic diarrhea virus on Manitoba hog farms. Influenza virus and porcine reproductive and respiratory syndrome virus are also a frequent challenge on some farms. African swine fever gets a lot of attention around the world. One disease that […] Read more

Vet advises against feeding grain to wild deer

A post showed up multiple times on my Twitter feed last week. The posted video showed a covered area with a make-shift table surrounded by a herd of deer voraciously munching on the grain strewn across its surface. The text of the original post was positive and to the effect of: ‘I feed them every […] Read more

Lung defences needed for respiratory disease prevention

The respiratory system in animals serves a vital function — without the ability to breath, animals will succumb within minutes. Clean air with oxygen is breathed in through the nostrils and transported down the trachea and through the tree-like branches, where it enters the lungs. Here, oxygen is exchanged for carbon dioxide, refreshing the blood […] Read more

Vet students learn about ecosystem influences on health

Veterinary students spend most of their final year in veterinary programs refining and practicing clinical skills. For cattle, this might entail working on pregnancy checking, perfecting bull testing, designing herd health programs and optimizing parasite control. In a variety of species, vet students practice surgical and anesthesia skills. But each year, a small group of […] Read more

Stress can bring on diseases caused by H. somni, which is why the stress of weaning and then commingling and transportation to auction markets or even directly to the feedlots seems to bring it on.

Stress can open the door for Histophilus somni bacteria

The disease organism known as Histophilus somni can cause many illnesses in feedlot cattle. This bacteria has been linked to pneumonia, arthritis, ITEME (infectious thrombo-embolic-meningo-encephalitis), as well as septicemia and heart failure. Stress can bring on diseases caused by H. somni, which is why the stress of weaning and then commingling and transportation to auction […] Read more



A recent study found that the average mortality from birth to 24 hours in calves from cows averaged 2.1 percent and in calves from heifers averaged 3.6 percent.  |  File photo

Benchmark data helps producers manage calf losses

Previously, I wrote about the economic importance of the calf-crop percentage. The calf-crop percentage is defined as the percentage of calves weaned per cow exposed to the bull. The calf-crop percentage is an easily measurable productivity trait and doesn’t require a lot of detailed records other than some inventory numbers at various times of year. […] Read more
