Jasmine Vickaryous – H5N1, a strain of the avian flu, is on the rise in the province and conservationists are urging Albertans to help limit the spread.
This article covers the growing concern that Avian Influenza is becoming Alberta and people can do to help the limit the spread to both wild birds, and their backyard flocks. Annemarie Pedersen from AFAC and Mark Boyce, Chair of Fisheries and Wildlife for the Alberta Conservation Association, both weigh in on the the issue and what practices should be implemented.
AgForLife – The Urban Hen Program is here in Calgary! As “eggs-citing” as this may be, many city-dwellers have no idea where to begin when starting a coop of their own.
This article interviews Cassandra Kirkpatrick, who is the instructor for all of the AFAC Urban Hen and Backyard Chicken programs. Here you can learn more about what to expect with urban chicken farming, how to care for your chickens, tips for building a coop, and more.
Doug Ferguson – Jody Wacowich, executive director of AgSafe Alberta, says the organization wanted to provide a less intimidating place for farmers to learn about dangers on the farm.
This article tells readers all about the new AgSafe program, FARMERS CARE, which is aimed at teaching producers how to identify hazards and manage the risks associated. The goal of this program is to help reduce the number of farm related injuries and deaths that occur every year.
Alex McCuaig – Planning and education for a catastrophic incident are key, whether it’s disease or a natural disaster.
“Arranging a plan just before a disaster is somewhat better but producers can find themselves up against others in the same boat, all attempting to get supplies such as generators at the same time.
There are some simple steps for planning for the worst-case scenario well in advance, said Husted, who emphasized the importance of contacting local fire chiefs or emergency managers to understand regional responses to disasters.”
On March 24, 2022, AFAC hosted a Technical Large Animal Emergency Response (TLAER) webinar to teach emergency responders more about equipment used during large animal rescues and how it can be adapted to different scenarios. Attendees of the event had the opportunity to learn from Dr. Rebecca Gimenez Husted, who is the owner of TLAER inc., and has over 25 years of experience instructing about large animal emergencies. Dr. Husted was joined by Victor MacPherson who has an extensive background in emergency care for both humans and animals, instructing, and fire and rescue.
(more…)March 16, 2022 (Calgary, AB) – The Livestock Care Conference kicked off this week with three engaging sessions on Tuesday. Starting with a highly interactive student workshop, our featured keynote speaker and rounding the afternoon off with three speakers from the agriculture ministries in British Columbia, Alberta, and Saskatchewan.
- Brad Andres, Director – Emergency Management Services, Alberta Agriculture, Forestry and Rural Economic Development,
- Graham Knox, Director – Climate Action and Emergency Management, (Ministry of Agriculture) Government of British Columbia
- Trent Catley, Director of Emergency Response and Inspection, Saskatchewan Ministry of Agriculture
These three speakers provided great insight into how their provinces are effectively implementing new strategies for emergency preparedness and response protocols. Discussing the importance of shelter in place plans, such as being able to be self-sufficient for up to 72 hours, and what that looks like in the event of an emergency, such as washed-out highways.
This session dove into the many facets that surround livestock emergencies, and how the provincial governments are working with farm/ranch owners to better communicate and handle emergencies. The importance of mass carcass disposal planning guides, relocation of livestock and even what to do during extreme weather events.
B.C. saw two extreme weather events this past year, the heat dome which helped to fuel summer wildfires and the mass rainfall and flooding last fall. Disasters like these show the incredible importance of collaboration between governments, emergency responders and farm/ranch owners.
Those who are interested in how each province addresses emergencies and what they are doing to further mitigate emergencies, predict them and respond quickly, can watch the recorded session through their conference link for up to three months.
(March 15, 2022) The first day of the 2022 Livestock Care Conference was a resounding success! Our keynote speaker Dr. Rebecca Gimenez Husted, owner of Technical Large Animal Rescue Inc., set the tone for the conference with a presentation about how the livestock industry can use the lessons learned from the COVID-19 pandemic and the B.C. floods to plan for future disasters.
“We know that the responsibility for the animals ultimately aligns with their owner, whether it’s a business or an individual,” said Dr. Husted. “So, people really need to start educating themselves and plan how they could handle things in the face of disaster.”
Dr. Husted explained that many people fail to plan until an actual disaster occurs. However, following the events of the past two years, the livestock industry has learned about the importance of planning and sharing information about emergency preparedness with each other.
Dr. Husted mentioned that individuals can prepare for future events by developing organized and devoted emergency efforts. These efforts can include attending local planning meetings, discussing emergency plans with fire chiefs, emergency managers and other community members, taking stock of critical infrastructure and creating biosecurity and safety measures.
“It does take effort. It does take realizing it could happen to you,” said Dr. Husted. “But we find that when people plan, it’s almost like a disaster is a non-disaster.”
Another lesson the livestock industry learned from the B.C. flood disaster was the importance of creating a variety of emergency plans. Dr. Husted mentioned that while some people had created a shelter in place plan during COVID-19, many did not have a plan for moving large animals in the event of a flood.
“That requires a lot of coordination with your local fire department, but it can be done and it has been done,” said Dr. Husted.
Throughout the session, Dr. Husted also talked about the importance of asking for help and using the internet to communicate with others during disasters to avoid personal and financial loss.
“The modern livestock person is connected,” said Dr. Husted. This is especially important in emergency situations because it can save the lives of humans and animals. “For example, many of the stranded farmers in B.C. were unreachable to the outside world and were basically on their own for several days or up to a week later.”
While mentioning the benefits of being connected during an emergency, Dr. Husted gave a nod to AFAC and Alberta’s Emergency Livestock Equipment Trailer program. With 19 trailers, Alberta is currently the most equipped province when it comes to livestock emergencies such as cattle liner rollovers and barn collapses.
“I’m really proud of the effort that your province has made to deal with not only livestock wrecks, but rescue situations where animals are in mud holes and things like that,” said Dr. Husted. “It really makes a difference, and it’s a huge part of emergency planning in Alberta.”
The main takeaways from Dr. Husted’s session were: prepare for emergencies by creating a variety of plans, share emergency plans, communicate with emergency managers and build a community of knowledgeable people to lean on in case of a livestock emergency.
If you missed this session and would like to watch it, a recording will be available for three months following the conference. We’re looking forward to hearing from more experts about PREP (prepare, respond, evaluate, progress) for Livestock Emergencies in the coming days!
March 17, 2022 (Calgary, AB) – Alberta Farm Animal Care (AFAC) is announcing Dr. Brenda Ralston, a livestock research scientist at Lakeland College in Vermilion, AB, as the recipient of the 2022 Award of Distinction. The annual Award of Distinction recognizes one individual or group who has made exceptional contributions to the field of livestock welfare, through either leadership, innovation or communication.
“Dr. Ralston’s dedication to Alberta’s livestock industry is inspiring,” said Nick Allan, president of Chinook Contract Research Inc. “Through her extensive and impressive research career, she has shown a personal and professional commitment to welfare and antimicrobial stewardship initiatives in the animal food production industry.”
Dr. Ralston began her 35-year career with Alberta Agriculture and Rural Development as a district agriculturist, moving to the role of beef specialist in 1994. During this time, she received her B.Sc. in Agriculture from the University of Alberta, M.Sc. in Veterinary Parasitology from the University of Calgary and a Ph.D. in Veterinary and Biomedical Sciences from Murdoch University in Perth, Western Australia. She is also a cattle producer and works with her family on their century farm, Twin Lakes Ranch.
Aside from her nomination from Lakeland College, AFAC received a number of other glowing recommendations from industry groups and fellow veterinarians. This is a testament to Dr. Ralston’s commitment to applied research and to her collaboration with private industry, producer groups, universities, government and most importantly the producers themselves. “Dr. Ralston’s research results in products producers can use to improve animal care practices. We can’t think of a more worthy candidate,” said Annemarie Pedersen, AFAC executive director.
Over her career, Dr. Ralston has supported and conducted multi-disciplinary livestock research for the poultry, dairy, lamb, horse and pork industries in the areas of pain control and pathogen mitigation. Most notably, she has helped bring livestock pharmaceuticals that address animal welfare issues related to management procedures to market, including:
- The Care-Ring anesthetic elastrator band to reduce the pain of castration.
- Oral Meloxicam for the beef, dairy and equine industries.
- An anti-bloat agent used to reduce animal discomfort when grazing alfalfa and enhance gains.
- Practical solutions to address antimicrobial resistance at the farm level for targeted selection of antibiotic groups for better animal outcomes and enhanced antibiotic stewardship.
One of her colleagues and nominators said it best. “As a result of her contributions, the way we think of pain in cattle has changed and now pain mitigation is common practice on farms and ranches across the province and the country,” said Dr. Denis Nagel.

On August 18, 2021, Alberta Farm Animal Care, in partnership with Alberta Pork Producers and Prairie Swine Health Services, hosted a Small-Scale Swine Webinar for individuals interested in small-scale pig farming. During the webinar, Dr. Kelsey Gray from Prairie Swine discussed various aspects of starting and operating a small-scale pig farm.
First, she discussed three Acts related to raising pigs which include the Animal Protection Act, the Alberta Water Act, and the Agricultural Practices Operations Act. These legislations are important to know for every small-scale pig farmer as they cover animal protection from abuse and neglect, water licensing, manure management, and finally deadstock management. Next on the list were the importance of traceability and having a PID (Premises Identification Number) for an operation. Dr. Gray outlined the various traceability programs in Canada and Alberta, including Alberta Traceability and PigTRACE, which is mandatory for all pork producers in Canada.
Dr. Gray then discussed the steps one should take when considering starting a small-scale pig operation. These steps include:

Craig Lester – As the mercury in the thermometer soars into the mid-to-high 30s (Celsius) this week it’s important to keep a sharp eye on your livestock for heat stress.
Dr. Melissa Moggy is the Extension Coordinator with Alberta Farm Animal Care.
She says there are a few symptoms you should watch for including the animals breathing faster.
“We call this an increased respiratory rate and so that might just be that their sides are moving faster or you might actually see that their mouth is open and they’re open mouth breathing,” Moggy said.
She says they often see that in birds, as they will open their mouths and their whole body will be moving as they try to expel the hot air and cool down. Moggy adds you may see that the animals don’t want to eat or drink.
Dianne Finstad – Sure, a lot of ranch work really is pandemic friendly, like feeding cows, baling hay, fixing machinery.
But let’s face it. Raising cattle, and in fact all of agriculture, is really a people business. Time and again you will hear it’s the people, plus the animals, that make this a special way of life.
So what happens to the social aspect when the whole world goes into a lockdown? Well, there’s been a whole lot of ‘try’ for new ways of meeting, sharing information, and doing issues work.
One of the first agriculture organizations to face the challenge was Alberta Farm Animal Care, with its annual Livestock Care Conference scheduled for Olds on March 19, 2020 – just a week after the first COVID-19 related lockdown. Speakers were coming from California, Georgia and B.C.
AFAC renews small flock webinar series
May 13, 2021
As urban and rural communities alike trade restaurants for coops and crowds for flocks, AFAC is excited to announce new sessions for its 2021 backyard chicken webinar series featuring hen expert Cassandra Kirkpatrick. Running from spring to fall, workshops cover a wide range of material that includes: coop design, breeds and flock behaviour, home care versus vet care and more. Registrants can expect to learn about bylaws and costs as well as obtain the certification needed to own backyard chickens in some municipalities.
The renewed interest in small flocks inspired programs that provide individuals with the tools and knowledge to care for their hens and provide the highest standards of animal welfare.

Sleep reportedly regulates a range of internal processes, plays a part in memory consolidation, and is governed by homeostatic and circadian processes. Thus, sleep is considered a critically important part of both mental and physical wellbeing for all mammals, with ‘sleep debts’ occurring when an individual fails to achieve an ‘optimal’ amount of sleep. The horse is no exception. Described as a polyphasic sleeper, the horse on average engages in several short sessions of sleep interspersed with longer periods of wakefulness resulting in a total of 3-5 hours sleep per 24 hours. Most commonly, equine sleep is observed between midnight and dawn, which is considered an evolutionary adaption by reducing the risk of attack at a time when the horse is most vulnerable. In a recent questionnaire-based study of nearly 600 horse owners, 29% reported never considering the amount of sleep their horse achieved, suggesting consideration of equine sleep may be under-prioritised when evaluating equine welfare within normal husbandry practices.

(more…)Doug Ferguson – The provincial government plans to allow consumers to buy animals directly from livestock producers for on-farm slaughter.
New provincial rules that allow Albertans to buy live animals directly from local producers for slaughter on farms will help ease a processing bottleneck made worse by the COVID-19 pandemic, said a beef producer.
“I think this new regulation creates a great opportunity for farmers,” said Blake Hall of Prairie Gold Pastured Meats near Red Deer. “As consumers become more interested in local food and farmers become more interested in direct marketing their animals, I think that this regulation helps marry those two nicely.”
He spoke at a recent webinar on the new rules hosted by Mountain View County north of Calgary. It was held in partnership with Alberta Agriculture and Forestry, along with the Young Agrarians, Grey Wooded Forage Association and Alberta Farm Animal Care.

Bovine respiratory disease (BRD), accounts for most of the disease and deaths in Alberta feedlots and feedlots in North America. Although BRD is a multifactorial disease, it is mainly associated with bacterial pathogens. Therefore, BRD is treated using antimicrobials, potentially playing a role in the development of antimicrobial resistance.

Multi-stakeholder partnership brings livestock transport regs to producers
Aug 25, 2020
Calgary, ALBERTA — A presentation from this spring’s Livestock Care Conference (LCC) has led to a new webinar series, to be offered by Alberta Farm Animal Care with technical expertise provided by the CFIA.
During our LCC in March, Nancy Simmons, a CFIA Meat Hygiene Inspector with a focus on humane transport, made a presentation on some of the key changes to transport regulations that will impact all livestock transportation in Canada. “The questions afterwards highlighted the great demand producers have for this information,” says Annemarie Pedersen, AFAC Executive Director.
They both saw the opportunity. A lot of information is specific to certain livestock sectors. “There are differences even between dairy and beef cattle for example. So why not provide specific sessions focused on each species separately? These AFAC webinars allow us to work with the industry directly and reach the producers and others involved in livestock transportation,” says Simmons.
“The series will include a CFIA presentation on the updated regulations and an extensive questions and answer period. We want to hear from the people who have to deliver on these changes and have a real discussion,” says Pedersen.
The first two sessions have been scheduled:
- Wednesday, September 9th in partnership with Alberta Pork
- Tuesday, September 22nd in partnership with Alberta Beef Producers
Other sessions are in the planning stages and will be announced as they are confirmed. Although the Alberta associations are collaborating on this series, it will be relevant and open to producers and stakeholders across the country. “Registration for this virtual webinar is free and we are very grateful for our provincial partners and the support of the CFIA for helping make this series a reality. We hope we will see producers from across Canada join as well. These rules and changes are the same for everyone,” says Pedersen.

Recently, Alberta Agriculture and Forestry reviewed and amended the Meat Inspection Regulation. Some amendments were focused on enabling innovation and change by removing red tape, improving clarity, and changing to a more outcome-based regulation. What that means is that the regulation now specifies a desired outcome that must be met, rather than giving instructions on how that outcome is reached.
The Meat Inspection Regulation also includes updated definitions on meat by-products and inedibles, categories of salvage, and directions on collecting, handling, storing, shipping, and labelling different categories of salvage. These changes will help abattoirs to salvage more meat by-products, improve access to specialty ethnic markets, and increase access to animal food. However, these products cannot enter the food chain if they are not inspected but may be used by the owner of the animal.
There is also a new license under the Meat Inspection Regulation. The Uninspected Slaughter Operation Licence is for anyone who owns land where on-farm slaughter occurs. This licence allows producers to sell a live animal to a customer and offer on-farm slaughter and processing services to the customer. Again, the meat is uninspected and is not for sale, but is for the consumption of the customer, who is the owner of the animal.
The final thing to change in the Meat Inspection Regulation is the future allowance of Meat and Dairy Inspection Section inspectors to perform video ante-mortems. This change will be finalized after the government has completed its research on video ante-mortem inspections. It will allow inspectors to perform their ante-mortem inspection, which is needed to sell the meat, from a real-time ante-mortem video of the animal prior to slaughter. This is ideal for animals that are unfit for transport, in emergency situations, or as approved by the Director. The carcass of the animal must be transported to a licensed abattoir within two hours to complete the slaughter process and to complete a post-mortem inspection. The inspected meat can then be sold for public consumption.

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.

Beef lameness team: Karin Orsel, Ed Pajor, Anice Thomas and Ben Caddey
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.

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.
