The four pillars of responsible beef production

/15 Comments/in , , , , /by

Alberta’s cattle feeders take great pride in the crucial role they play in producing our province’s world class beef – and in using responsible and sustainable production methods.

Here at the Alberta Cattle Feeders’ Association (ACFA), we support our members in continuous improvement under four pillars:

1. Animal care

Alberta’s cattle feeders believe in treating the animals that feed us with care and respect. They follow the National Beef Code of Practice to ensure the finest in animal care, food safety and sustainability.

Two key programs that help them maintain the highest standards of animal care are:

-The Feedlot Animal Care Assessment Program

-The Canadian Livestock Transportation Certification

2. Animal health and production

Ensuring the health and well-being of livestock is a top priority for feedlot operators. ACFA is heavily invested in helping through initiatives such as the new histophilosis vaccine, and through forage and feed grain research.

3. Environment

Cattle feeders work hard to minimize environmental impact from their operations. 

ACFA has participated in several initiatives:

-The Feedlot Emergency Preparedness Plan which protects animals, the environment and human health in the event of an incident such as a disease outbreak or a natural disaster. 

-Environmental impact studies, such as Alberta Agriculture and Resource Development’s Livestock Impact on Groundwater Quality in Alberta.

-Interaction with the Natural Resources Conservation Board on environmental initiatives.

-Membership of the Intensive Livestock Working Group and Agri-Environmental Partnership of Alberta. 

–Project Clean Cow.

4. People and communities

Protecting people, and the communities in which they operate is important for cattle feeders. Food safety, farm safety and community service are at the centre of their everyday operations.

It is on these four pillars that Alberta’s cattle feeders operate in the most responsible manner possible. They strive to ensure excellence in animal care, food safety, farm safety, and respect for people and their communities. At ACFA we are working hard to support them in those efforts.

Should Canadians be concerned about antibiotics in food animals?

/10 Comments/in , , , /by

Last week in part one of this three-part series, we explained why and how antimicrobials (of which antibiotics are one type) are used in beef cattle. This week we’re exploring the causes for concern over that use.

We continue our conversation with Dr. Sherry Hannon, research team lead and veterinary epidemiologist at Feedlot Health Management Services Ltd.

How long do antimicrobials stay in an animal’s system?

There are many different antimicrobials labelled for veterinary use in cattle in Canada. Each is classified according to its uses, its effect on bacteria and the way it works.

“As part of the label, a ‘withdrawal period’ – a period of time before which the animals are not allowed to enter the food chain – is specified. Some antimicrobials have a zero day withdrawal period (they are eliminated from the body within a very short period of time), while others are known to stay in the body for much longer periods,” Sherry explained.

Causes for concern in the use of antimicrobials

Sherry explained that there are two main concerns related to the use of antimicrobials:

1. Antimicrobial residues

A residue is a remnant of the antimicrobial molecule itself or a degradation product of that molecule, left in the animal after harvest.

“For each antimicrobial, a level of residues (usually extremely low) has been deemed to be acceptable for human health through rigorous safety trials,” said Sherry.

“Therefore, meat that goes for sale to people must be at or below that level. The withdrawal period for each antimicrobial defines the amount of time that must have elapsed from the last dose before an animal can be harvested for meat, thus ensuring any possible residues are below the acceptable level and safe for human consumption.

As an added step of food safety oversight, meat at processing plants is regularly tested for residues on an ongoing basis as part of quality assurance and compliance monitoring.”

2. Antimicrobial resistance

According to Sherry, of greater concern than residues is the issue of antimicrobial resistance, which for many reasons, has become a global health issue. As the use of antimicrobials continues, for people and animals, there is increasing development of bacteria that are resistant to them.

“There is a potential for the presence of bacteria on meat or in the environment which carry resistance genes for particular antimicrobials, and this relates to the possibility that these bacteria could multiply or infect people,” she said.

The role of continued research and monitoring

“The above concerns are actively addressed through continued research, regulatory requirements, veterinary oversight, antimicrobial stewardship practices, and producers’ commitment to provide safe and nutritious beef,” noted Sherry. “In addition, appropriate cooking of beef further protects against these concerns by inactivating any residues present, or by killing any viable microorganisms,” she stressed.

The Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) monitors and describes antimicrobial resistance (and some use) in retail meat, on farm and in animal and human populations.

Stay tuned for part three of this series, in which we’ll discuss how food safety is ensured when antibiotics are used in cattle – and ongoing changes to regulation.

Antimicrobials and food production – 4 reasons antibiotics are given to beef cattle

/15 Comments/in , , /by

Some Canadians have questions about antibiotic use in farmed animals. In an earlier post, we looked at the science behind the use of hormones in beef cattle. This week, in part one of a three-part series, we’re exploring another hot topic – antibiotics.

First up, an explanation of what antibiotics are, and how and why they are used.

Antibiotic or antimicrobial?

An antimicrobial is any agent that is used to treat microbial infection. An antibiotic is one type of antimicrobial, specifically made from natural microorganisms.

When looking at the safety or issues of using antibiotics in beef cattle, it makes the most sense to discuss the use of antimicrobials as a whole, rather than only antibiotics.

We spoke with Dr. Sherry Hannon, research team lead and veterinary epidemiologist at Feedlot Health Management Services Ltd. to learn more about the use of antimicrobials in feedlot animals.

Sherry explained that there are four main reasons for the use of antimicrobials in feedlots:

#1 To treat disease

“Diseases such as respiratory disease, arthritis and other lameness, abscesses, etc., are effectively treated with antimicrobials in injectable or oral form,” said Sherry.

#2 After surgery or injury

Antimicrobials are used to prevent infection in individual animals after specific events.

#3 As a preventative

Antimicrobials are sometimes used when animals have been exposed to disease, or unfavourable environmental conditions, and are at risk from an outbreak of infectious disease. They are also fed to groups of cattle at specific times to help prevent common diseases.

“Based on clinical field trials, we know that specific groups of animals may already be sick by the time they reach the feedlot after weaning, co-mingling in auction markets, and transport,” explained Sherry. “Antimicrobials help us prevent outbreaks that could spread through the herd.”

#4 To improve growth and production

The use of antimicrobials have historically been used to improve rumen function and enhance growth and production of meat, but this use is declining, and becoming increasingly regulated, due to the risk of antimicrobial resistance. We will discuss antimicrobial resistance further in part two of this series.

When antimicrobials are withheld

When an animal is sick, or at risk from disease, it would be cruel to withhold treatment.

“There are three main health implications when antimicrobials are withheld,” Sherry noted:

    • Poor animal welfare – animals would become sick or die.
    • Greater potential for spreading of disease among animals in a pen.
    • Food safety concerns increase because animals are more likely to have infections when sent to slaughter.

Stay tuned for next week when we will discuss the causes for concern around the use of antimicrobials in beef cattle, and what’s being done to address them.

How technology is helping improve feedlot efficiencies

/21 Comments/in , , /by

If you’ve spent any time at a feedlot or on a cattle ranch, you might have noticed the numbered ear tags worn by each animal. More than a simple numbering system, these tags are sophisticated tagging and tracking devices that contain detailed, up-to-the-minute information about each individual animal.

Radio Frequency Identification (RFID) tags are part of an industry-driven program, administered by the Canadian Cattle Identification Agency, and have many different purposes, such as age verification and traceability. But they are helping with more than just tracking. At Cattleland Feedyards, RFID tags are an integral component of a Residual Feed Intake (RFI) research program being conducted in their Integrated Beef Research Station (IBRS).

To learn more, we spoke with Sarah Van Schothorst, a research assistant at Cattleland:

Q: How is RFID technology used to monitor cattle feeding?

Sarah: Here at Cattleland, we use a feeding system created by GrowSafe Systems to measure individual feed intakes. Each animal eats at a feed bunk, which is a large feed tub on weigh bars, or load bars, which measure the food given. The system automatically reads the tag and starts collecting data on the amount consumed. The data is wirelessly transferred to a panel in the feedyard and then to a computer.

Q: Why is it important to measure intake in this way?

Sarah: We use the technology to help us monitor the feed efficiency of potential breeding bulls. We are able to determine which animals are gaining weight while eating less, through the calculation of feed to gain ratios. This is called ‘residual feed intake’, and it’s an inheritable trait. Having technology available that allows us to monitor individual intakes allows us to select genetic lines that will be more cost effective and more environmentally friendly due to less consumption of resources during the animal’s production life.

The technology also allows us to identify individual animals with reduced intakes, leading to earlier detection of animals that will need treatment.

Q: Who monitors the data, and what actions might follow?

Sarah: This technology is fairly labour intensive. GrowSafe Systems monitors all of their systems and records the data for each trial, and for each cattle pen. At Cattleland, I work with the GrowSafe support team to ensure that the animals are in the best condition, feeds are delivered properly, and the system is in working order by doing necessary maintenance and any repairs. The bunks need to remain clean and the load bars free from debris that may affect weighing of the feed or data collection.

Q: How long has this technology been used?

Sarah: GrowSafe Systems developed the technology in Canada starting in the mid- to late 90s. Cattleland implemented its use in 2002-2003.

Stay tuned for upcoming posts where we will continue our technology theme, and look at other ways innovation is helping make the cattle feeding industry more efficient and more sustainable.
