As many of us have heard, recent amendments to the Humane Transportation of Animals regulations took effect on February 20^th, 2020. Regulations can be difficult to interpret and understand. We can’t all read legalise!

Sheep production is on the rise in Canada, largely due to the growing ethnic market. This means that the number of lamb feedlots is also increasing to meet this demand. As with most intensive production systems, some health and welfare issues are reduced as a result of greater ability and opportunity to manage animal health while other issues may increase since disease can be more easily spread. This is true in the case of lameness, which can be caused by either infectious or non-infectious sources. Regardless of the cause, lameness is a significant animal welfare and economic concern known to be painful for the animals and costly to producers due to production losses and increased treatment and labour costs.

Digital dermatitis (DD) has been reported in North American feedlots, but the cause is still not fully clear. DD causes ulcers on cattle feet and often results in lameness. The beef lameness team at the University of Calgary, decided to look at foot and leg conformation as well as pen conditions as factors that make it more likely for a feedlot animal to have DD. A better understanding of the potential role of each variable should provide new ideas to improve prevention and treatment.

During the era of Covid-19, these unprecedented times bring high anxiety as we do not have all the answers. One minute, we’re told not to wear masks, and the next, well…you better get yourself a mask.

The pig industry is certainly not free from the anxiety of this evolving situation. Initial reactions by our pork producers regarding Covid-19 started with the concern “can pigs get Covid-19?” and “What am I going to do if our workers get sick? Who will care for our pigs?” and unfortunately in some areas, the heart wrenching question is now being asked “How do I mass euthanize my pigs?”

Surprisingly, we know very little about the effects of providing beef calves a rest (including feed and water) mid-way through a long-haul (>12 hours) transport. Finding an answer to this question has become more important due to recent changes to the Canadian humane transport regulations implemented by the Canadian Food Inspection Agency (CFIA) in February of this year. The proposed changes state that un-weaned and weaned calves can be transported a maximum of 12 and 36 hours, respectively, before an 8 hour rest is required. To provide producers and policy makers with science-based information we conducted a study evaluating the effects of different rest stop durations after different lengths of transport on indicators of welfare in 7-8-mo-old conditioned beef calves.
