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.

Transportation is a stressful experience for all livestock. The care of animals during transport is a significant welfare concern. Transportation begins with the selection of animals for transport and ends with unloading animals at their destination. The Health of Animals Regulations (HAR) Part XII applies to all forms of animal transport in Canada, such as trailers, trains, and vessels. It is enforced by the Canadian Food Inspection Agency (CFIA). The CFIA can conduct an inspection at any time and at any location where animals are transported, including abattoirs, auction markets, and assembly centres.

A few years ago cattle in an American feedlot went down during transport to a packing plant, and others developed severe lameness. This condition was eventually labeled fatigued cattle syndrome (FCS) and became a huge animal welfare issue due to the appearance of severely lame, non-ambulatory cattle.

Four students from the University of Alberta are conducting a capstone project with mentorship from Alberta Farm Animal Care and faculty member, Dr. Clover Bench. We were initially asked by the course professor for project ideas, and we considered multiple producer challenges on which to focus. Producer mental health was a consideration as we know that it is closely related to animal welfare. However, we realized that, with so many challenges that producers face, we need more information on what producers perceive are their biggest challenges. Regardless of what challenges are highlighted, they would have an impact on their mental health if producers feel overwhelmed and not supported.

Beak treatment of laying hens is an important management practice as it is one of the most effective methods of controlling or eliminating cannibalism within egg-production flocks. Infrared beak treatment (IRBT) is the most commonly used methodology in Canada, and the available literature shows that IRBT has less of a negative impact on production and welfare than with other methodologies.

The livestock industry is coping very well and making great strides with addressing the topic of decreasing antimicrobial usage which indirectly helps with antimicrobial resistance. From veterinarians setting the example and producers from the cow-calf sector to the feedlot implementing effective coping strategies, huge progress is being made. There are management changes which can be made to minimize disease incidence. The policymakers can also look at ways to increase research in antimicrobials or alternative treatment methods. Monitoring and surveillance of drug resistance such as the Task Force headed by the veterinary colleges to look at the evolution of antibiotic resistance has been formed. What can you do today as a cattle producer in whichever segment of the cattle industry you are involved in? This article will address changes you can make to hopefully decrease disease incidence and therefore the need for more antimicrobial usage in your calves.

In British Colombia (B.C.), there are over 1500 outdoor small lot pig producers and this is expanding in Alberta and across Canada. This type of production is growing as “farm-to-fork” movements and eating local are increasing in popularity. As this group grows, we recognize that there is a gap in knowledge about raising pigs safely, humanely, and efficiently outdoors.

How we manage birds has a huge impact on their productivity, health, behaviour, and profitability. Lighting programs are an important management tool for poultry production. Traditionally, broiler chickens have been raised with little (1 hour) or no dark, with the belief this allowed them full visual access to their environment now know that birds need a period of darkness for optimal welfare and production. When birds are given a continuous period of 4-6 hours of darkness in a 24 hour period, they are more productive, healthier, more active, and sleep better.

The objective of this research was to understand the effects of different durations of darkness on broiler performance, feeding behaviour, and feed rates.

Stocking density has the ability to directly influence economic return for producers however, it is important to consider other factors that may be affected by stocking density. While the majority of stocking density studies were conducted in the 1990’s or earlier, past studies have well documented the effects of stocking density on performance. There are few studies that evaluate how stocking density impacts the health, behaviour and overall well-being of the bird.

Another issue with stocking density research is that there are many other factors linked to stocking density that contribute to negative bird performance and welfare, such as feeder and drinker space, poor air quality, and poor litter quality. This study attempted to account for these factors by equalizing feeder and drinker space on a per bird basis, monitoring air quality for CO₂ and ammonia and adjusting ventilation based on stocking density, and by evaluating litter moisture.

The aim of this research was to study the effects of stocking density with a comprehensive approach, ensuring that confounding factors were accounted for.

I fell in love with honey bees after having the opportunity to do a couple hive inspections with a professor while I was studying abroad. When I returned to Canada to finish the second half of my masters degree on an invasive fish species in Alberta, I decided to take a beginner beekeeping course. Needless to say, my fascination with these creatures only grew stronger. A year after I graduated, I was lucky to land a job working as an apiculture research technician at Alberta Agriculture and Forestry. As of right now, I am hoping to expand my knowledge of honey bees and colony management, as well as develop specific technical skills to help the industry diagnose and manage pests and diseases. 

The beekeeping industry in Alberta is the largest in Canada, and is home to over 315,000 honey bee colonies. Both honey production and the provision of pollination services to crops in Alberta and British Columbia are key aspects of the industry. Our goal at Alberta Agriculture and Forestry is to support Alberta’s beekeepers to ensure the industry is strong and resilient, and honey bees are healthy for the future. One of our primary objectives is to assist beekeepers in developing and applying Integrated Pest Management (IPM) systems in their operations to reduce the risks and costs associated with colony loss from disease outbreak.

“Be kind, for everyone you meet is fighting a hard battle.” ― Socrates

There is nothing quite like the pain, of witnessing someone that you love suffer. The feeling of powerlessness in not being able to make the mental anguish of another disappear. But here’s a little secret. No one always has it together. Every life is laced with adversity, sadness and grief. The belief that we need to manage on our own is changing, bringing us back together. There is great courage in sharing our stories.

Lameness is the third most common health problem and reason for involuntary culling in the Canadian dairy industry, after reproductive performance and mastitis. This disorder is a sign of pain resulting in an abnormal locomotion, gait or posture. Beside this welfare impact, it has a major economic impact, including treatment costs and reduced milk production, reproductive performance, and cow longevity. Current scientific knowledge has not been effective in adoption of prevention strategies as the average lameness prevalence in Alberta is still 20%. The Canadian Dairy Code of Practice aims to have 10% lameness as a maximum. Two students will present the focus of their projects to mitigate lameness. (more…)

Commercial livestock systems, regardless of the species, are typically geared towards promoting good health and production of the animals. Other factors that might be important to the animals, such as ability to perform natural behaviours, do not necessarily take precedence. The Animal Welfare Team at AgResearch in New Zealand has been exploring how we can shift on-farm practices to be more focused around animals’ natural behaviours. These management shifts are often informed by the animals’ preferences and may be quite simple.

Sheep production in Canada is increasing (one million head on 11,000 farms of which 2,000 farms are in Alberta), due to the growing demand for lamb meat by consumers over the last five years as a result of growing ethnic markets. Consequently, both ewe flocks and growing/finishing lamb feedlots have been increasing in number and size within Alberta to meet the demand for this growing market.
Lameness is a common cause of welfare and economic concern in most sheep producing countries. For example, prevalence of lameness in UK sheep farms has been reported to be between eight and 10 per cent with the main cause being, interdigital dermatitis, severe footrot, ovine digital dermatitis, and shelly hoof (Kaler and Green 2009*). In Alberta, we see lame sheep on farms, feedlots, auctions and pasture. At one time, there was a provincial footrot eradication program. Veterinary inspections, foot trimming and foot-soaking were standard annual procedures for the 20,000 plus sheep that headed to B.C. forestry reserves. Despite all the effort, time and money, lame sheep are still common. (more…)

In 2014, the World Health Organization (WHO) recognized the increased development of antimicrobial resistance (AMR) as a global crisis. Dr Keiji Fukuda, Assistant Director-General of WHO stated, “Without urgent, coordinated action by many stakeholders, the world is headed for a post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill.” This will affect generations to come. Later that year, our federal Minister of Health demanded that an action plan be developed by Health Canada to address this issue in Canada. (more…)

On-farm emergency slaughter (OFES) is one end-of-life option for farm animals that cannot be transported humanely but are fit for human consumption. OFES – whereby veterinary inspection, stunning (using a firearm) and bleeding occur on the farm before the carcass is transported to a slaughterhouse for processing – is allowed in several Canadian provinces including Alberta. The stated goals of most OFES programs are to prevent undue suffering of an injured animal and to salvage meat. (more…)
