Calving season is upon some of you and just around the corner for many more. Half of those calves will be castrated. Research has shown that it’s best to castrate calves at the youngest practical age to minimize pain and speed recovery. The 2019 “Adoption Rates of Recommended Practices by Cow-Calf Operators in Canada” study indicated that over half of cow-calf producers in Ontario, nearly 70% in Atlantic Canada, and over 90% in Western Canada reported castrating calves before 3 months of age. Within the last decade, practical, affordable, effective pain control products like meloxicam have become available (i.e. Metacam, Rheumocam, Oral Meloxicam, Meloxidyl). These can help reduce the pain of knife and band castration in calves as young as 2 months of age. Up to a quarter of cow-calf producers in Western Canada and Ontario report using pain control, depending on when and how they castrate calves.
But research shows that week-old calves show fewer physiological or behavioural signs of castration pain than older calves. I used to think that very young calves were simply more pain tolerant. It’s probably more complicated than that. For one thing, a newborn calf has just spent 9 months connected to their mother’s life support system. Like a cold tractor, it can take some time for the newborn’s systems to “boot up,” stabilize, and become fully operational. The pain response may be part of that – the calf may feel pain, but not fully able to respond to it, sort of like a human patient with “locked-in” syndrome who’s paralyzed and unable to speak but still fully conscious. On top of that, birth is a physically taxing experience for both the cow and calf. The newborn calf may simply be unable to respond to the additional stress or pain of castration. Continue reading
The most important day of a calf’s life is the first one. There are some key factors that play a role in whether or not a baby calf gets off to a good start and research has demonstrated that the first 24 hours of life are critical in order for a calf to survive to weaning and beyond.
Interventions – follow-up care is important
Dystocia, or calving complications, pose a health risk for both the newborn calf and the cow. While dystocia can be partially managed with careful breeding choices and culling practices, proper nutrition, and managing for a body condition score of 3 (on a scale of 1-5) before calving, difficult deliveries can still occur.
Every scenario is different, however once a water bag appears, a calf should hit the ground within one hour for cows, or up to one and a half hours for a first-calf heifer. If this doesn’t happen, intervention may be needed, especially if no progress has occurred for thirty minutes, the cow stops pushing, or there are other signs of trouble. If there is a problem, a water bag may not always appear, so be observant of other behaviours that signal labour, such as tail switching, restlessness, the appearance of membranes or discharge, or a kink in the cow’s tail.
Sometimes it can be hard to know where you’re going if you don’t look at where you’ve been. For decades, research and extension organizations have promoted many practices to beef cattle operators with the goals of improving production, product safety, and ultimately profitability. Recently, the Beef Cattle Research Council (BCRC) and Canfax Research Services created a comprehensive report outlining the adoption of recommended beef management practices over time and across Canada.
The analysis used a broad lens to examine all cow-calf practices from feeding methods to manure management, calving cows to retaining heifers, pasture management to feed testing, and everything in between. Recent data from regional cow-calf surveys and research studies were compared to foundational producer survey and Statistics Canada information dating as far back as thirty-five years.
The first of its kind, this analysis:
- Consolidated benchmarks for parameters such as conception rates, weaning weights, death loss, and calving season length;
- Compared current practices and highlighted long-term trends across Canada where possible;
- Identified gaps in adoption and potential extension opportunities;
- Recognized and addressed barriers for adoption.

When Canada’s 2013 Code of Practice for the Care and Handling of Beef Cattle was being developed, some participants felt it should require pain control for castration at all ages, like the dairy code. The producers and researchers on the beef Code committee were confident that pain control was beneficial for feedlot bulls and dairy calves but were concerned that there was no research showing whether nursing beef calves and individually-housed dairy calves respond to castration or pain relief the same way.
In the end, the 2013 beef Code required that castration be performed by an experienced person using proper, clean, well-maintained equipment and accepted techniques. Producers are expected to seek guidance from their veterinarian on the optimum method and timing of castration, as well as the availability and advisability of pain control drugs for castrating beef cattle. Calves must be castrated as young as practically possible, and pain control is required when castrating bulls older than six months of age. Continue reading
Industry data provided by production surveys can serve as a benchmark for production performance across the country. Historical production surveys include the Alberta Cow-Calf Audit (1986-88, 1997-1998) and “Reproductive Efficiency and Calf survival in Ontario Beef Cow-calf Herds” (1983). Sixteen years later, the survey was revived, revised and expanded into the Western Canadian Cow-Calf Survey (WCCCS, 2014). In the last two production years, additional surveys have occurred across Canada (Western Canada, Ontario, Northern Quebec, Atlantic). These have provided an overall picture of current production and management practices on beef cow-calf operations in each region of the country for the first time. The objective of these surveys were multi-faceted.
Canadian Cow-Calf Surveys
Beef producers are busy in the spring and summer months processing cattle, performing common procedures such as castration and dehorning. Producers may also brand their cattle as a form of identification. These practices are commonplace on beef farms across Canada, and in many cases are necessary for the long-term health and welfare of the animals, however they cause pain. Reports show that producers and veterinarians who incorporate pain control measures during painful procedures often describe ease of use and potential improved gains in their herds.
Pain control is becoming a priority among producers and scientists as anesthetics and analgesics, including non-steroidal anti-inflammatory drugs, are more readily available.
How can producers mitigate pain in beef cattle effectively? Are there practical ways to manage pain in real life conditions? What is a Continue reading

Canada’s Code of Practice for the Care and Handling of Beef Cattle requires that castration be performed by an experienced person who uses proper, clean, well-maintained equipment and accepted techniques. A producer is expected to seek guidance from their veterinarian on the optimum method and timing of castration, as well as the availability and advisability of pain control drugs for castrating beef cattle. Calves must be castrated as young as practically possible, and pain control is required when castrating bulls older than six months of age.
The requirement to use pain control in older calves was based on research demonstrating its effectiveness in feedlot bulls. A lot of information was also available regarding the use of pain drugs in baby dairy calves, but the beef producers and researchers on the Code committee felt that the vast differences in genetics, herd dynamics and familiarity with people meant that nursing beef calves may respond differently to castration than individually-housed dairy calves that had been weaned at birth. A research project funded by the Beef Science Cluster is helping to determine when pain control is beneficial in beef calves. As a first step, students working with Karen Schwartzkopf-Genswein (AAFC Lethbridge) and Ed Pajor (University of Calgary) examined how Continue reading

Marketing executives for grocery and restaurant chains track consumer perceptions and attitudes towards issues like livestock production practices, animal welfare and pain control. These surveys sometimes lead to initiatives that impose specific production standards on suppliers so the company can distinguish itself and showcase its products.
From the other side, animal welfare researchers study how beef cattle respond to painful procedures like castration, dehorning and branding, and the benefit of providing pain medication. This knowledge is central to updating the science-based Code of Practice for the Care and Handling of Beef Cattle.
But what about the producer, who’s responsible for day to day animal care, and who pays for the added costs of any production requirement that is ultimately imposed by law, industry standard, or marketing programs? A better understanding of what motivates (or discourages) producers when it comes to animal care is critical, if new pain control practices are to be adopted.

With Fall around the corner, it’s a good time to (re)consider a few production practices. These 5 articles are full of ideas, scientific evidence, producer testimonials and interactive calculators. By taking a closer look at their options and potential, you may discover more ways to benefit your herd and bottom line.
Feed cows, not worms
Managing internal parasites
Internal parasites can be much more detrimental to your bottom line than you may realize. Effective parasite control can have a greater economic impact on cow calf operations than many other management procedures.

There is no shortage of beef industry conferences, workshops and meetings for Canadian beef producers to attend throughout the year. These have included the Canfax forum, the Canada Beef forum, Cattlemen’s Young Leaders forums, industry golf tournaments, tours, national, provincial and breed association meetings, the International Livestock Congress, and many more. Although they are valuable events, it is hard for producers to attend every event they might wish to. It can also be frustrating when similar speakers or themes get addressed at several different meetings, and busy producers take extra time away from their operations to hear the same presentations multiple times. The last thing anyone needs is to make time for yet another industry event.
