Vaccines Are Cheap Insurance – Don’t Let Your Premiums Lapse

After last summer’s pasture conditions and last winter’s feed costs, it’s safe to say that many cow-calf producers are facing the upcoming grazing season with some anxiety. Some are looking for new grazing arrangements, opportunities to trim input costs, or both. No single solution can solve every challenge for every operation, but nearly all decisions have trade-offs. Using a community pasture or other shared grazing arrangement may reduce pasture costs but mixing different herds can spread reproductive (and other) diseases. This risk is magnified if you’re tempted to save costs this year by skimping on your vaccination program.

The February and March editions of this column drew from a large beef cow productivity study that happened to coincide with the 2001-02 drought in Western Canada. That study also revealed how important vaccination programs are to maintaining reproductive performance. These results were published in Livestock Science 163:126-139 and Theriogenology 79:1083-1094; 81:840-848.

What They Did:

To recap, Dr. Cheryl Waldner and her colleagues from the Western College of Veterinary Medicine studied the productivity of over 30,000 beef cows in over 200 well-managed herds in Alberta, Saskatchewan and B.C. Participating producers individually identified each cow and calf, recorded all calf births (including abortions), maintained an active veterinary-client-patient relationship, had good animal handling facilities, pregnancy tested all breeding females, had a veterinarian evaluate all herd bulls, had an established spring or summer breeding season (i.e., didn’t calve year-round), and worked with the researchers to collect the needed samples and data.

As part of the study, they compared the pregnancy and abortion rates in these herds, based on whether they used community pastures and whether they vaccinated their cows against BVD and IBR before the breeding season. These two diseases don’t just affect calves; they can also reduce reproductive success in cows. Continue reading

Calf 911 – How to Spot Dehydration in Young or Scouring Calves *New Video*

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 calves is a simple and effective practice that can make a big mark on your bottom line.

Calves with scours are at a high risk for dehydration and hypothermia. When calves infected with neonatal scours die, it is ultimately because of dehydration, not the pathogens that cause the disease. Having practices in place on your operation to identify, manage and rehydrate calves suffering from scours or other causes of dehydration can increase the chance of recovery and optimize the health and wellbeing of young calves.

Here are some steps producers can use to evaluate the dehydration and health status of young calves: Continue reading

The Cost Benefit of Using Vaccines: BVD



Vaccination is a proven tool for disease prevention. Vaccination recommendations vary by region and by farm as the environment, production, and management practices can increase or decrease the amount of risk cattle are exposed to. Disease exposure occurs in numerous places including community pastures, fenceline contact with neighbouring cattle, auction markets, and breeding cattle, such as bulls, purchased from other herds. However, vaccinating breeding females for reproductive disease and calves for respiratory disease are recommended practices across Canada. A vaccination program should be developed in consultation with a veterinarian who can determine which ones are necessary for your area.

In western Canada, one in ten producers surveyed are not vaccinating their cows for infectious bovine rhinotracheitis (IBR) and bovine viral diarrhea virus (BVD) (Waldner et al., 2019) and more than a quarter of producers do not vaccinate cows for other reproductive diseases (Beef Cattle Research Council, 2019). One third of Ontario producers do not vaccinate their cows for BVD and far fewer vaccinate for other reproductive diseases. In Atlantic Canada, 27% of producers reported not administering general vaccinations. This leaves herds vulnerable.
