Waste Not Want Not

When I was a kid, “no dessert if you don’t finish your supper” encouraged us to eat everything on our plates. Others grew up with the guilt-based “children are starving in the third world” approach. There are more than twice as many people on earth today as there were 40 years ago, so issues like food security and “food loss and waste” are gaining attention. Every year in Canada nearly a tonne of food is lost or wasted per person. The federal Food Waste Challenge is part of Canada’s commitment to the United Nations (UN) goal to reduce global food loss and waste by 50% by 2030.  Food waste is more than just the unidentifiable and vaguely menacing leftovers in the back of your fridge. In fact, food loss and waste are defined as any crop or livestock product that doesn’t directly reach a human mouth.

But some of this food loss and waste does reach human mouths indirectly, through livestock. As part of a Beef Cluster project, Dr. Kim Ominski and collaborators from the Universities of Manitoba and Lethbridge and Agriculture Canada are examining how livestock help reduce food loss and waste. Their first report “Utilization of by-products and food waste in livestock production systems: A Canadian Perspective” will be published in Animal Frontiers. Here are some of their key findings so far. Continue reading

The Cost Benefit of Using Vaccines in Beef Cattle

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, fence line 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. Continue reading
