Calf 911: Managing colostrum so newborn calves thrive
Ensuring newborn calves consume colostrum is one of the most important management strategies cow-calf operations can implement to promote healthy calves. Colostrum provides essential antibodies (such as immunoglobulin G or IgG) to a calf with virtually no immune system. Colostrum also contains fats, vitamins, proteins and other immune cells essential to provide the calf energy, […] Read more

Calf 911: How to spot dehydration in young or scouring calves
It’s a great feeling when a calf arrives on the ground safe and sound. Ideally, things go well, and cows and newborn calves thrive. However, it’s important for producers to take the time to look for signs of early illness in neonatal calves. Being able to recognize the symptoms of disease and dehydration in baby […] Read more

Dust a risk factor in calf pneumonia
Vet Advice with Dr. Ron Clarke
When drought and the Great Depression introduced the 1930s, the wheat market collapsed. Oceans of wheat had replaced the sea of prairie grass that anchored the topsoil into place. Once the wheat dried up, the land was defenseless against the winds that buffeted the Plains. The term “dust pneumonia” originated during the Great Depression when […] Read more

A tale of two calving systems
Confined and pasture methods each have risks and benefits
For beef producers, calving season can be both stressful and enjoyable. Witnessing new life can be refreshing, but calving time is the most critical period in the cow-calf production cycle. Whether or not calving season is a success will set the tone for an operations’ entire year or longer, having an impact on animal health, […] Read more

Everything old is new again – treating chronic mycoplasma
Research on the Record with Reynold Bergen
Cattle were ideally created (or evolved) to consume and digest high fibre diets. Whoever (or whatever) was responsible for designing the rumen so elegantly probably should have paid more attention to the respiratory tract. The design of the bovine respiratory tract makes it easy for BRD bacteria such as Mannheimia, Pasteurella, Histophilus and Mycoplasma to […] Read more

BVD still a threat to Canadian cattle herds
Even closed herds can be at risk for BVD, making vaccination key to preventing this disease
Bovine viral diarrhea (BVD) can affect cattle in many ways, causing abortion, birth defects, stillborn calves, immune deficiencies in persistently infected animals, and other acute or chronic illness. BVD is also an indirect cause of many other diseases because it has adverse effects on the immune system. An estimate a few years ago suggested that […] Read more

Make vaccinations work for your cattle herd
When giving a shot, make sure it isn’t a shot in the dark
As ranchers begin another calving season and vets stock their shelves with vaccines and supplies, now is the time to review vaccination protocols and management practices to make sure the herd is protected. Dr. Glen Griffin of South West Animal Health Centre in Swift Current, Sask., has been serving the southwest since 2004, when he […] Read more

Scours in calves
Scours is a common illness in young calves. Understand the causes and effects of this disease to treat and prevent it
Scours can be caused by certain kinds of bacteria, viruses or protozoa, but other factors come into play as well. “It’s often the interaction between the immune system, the environment and the pathogen load. The old saying is that the solution to pollution is dilution (or) minimizing the pathogen load,” says Dr. Paul Hardes, a […] Read more

Keeping trichomoniasis out of cattle herds
Prevention and early detection are vital to managing this disease
Trichomoniasis is a disease that can sneak into a herd without any obvious signs. This sexually transmitted disease is caused by protozoa that inhabit the cow’s reproductive tract and the bull’s sheath. It doesn’t affect a bull’s fertility rate, but a bull can spread the disease to many cows during breeding. An infected cow can […] Read more

Managing resistance to internal parasites in cattle
Producers need to tailor parasite control to align with their herds and management systems
Managing internal parasite resistance starts with asking the right questions and understanding the principles of antiparasitic resistance and the range of control products. From there, a producer needs to develop a deworming strategy and pin it to the spring and summer grazing calendar. A veterinarian can help. Antiparasitic resistance is typically defined as the genetic […] Read more
