Bovine Respiratory Disease from the Farm to the Feedlot

Weed seeds and invasive species may be present even in well-managed pastures and rangelands, but it is hard for them to germinate, establish and spread in healthy, competitive forage stands. Stresses like severe drought, overgrazing, heavy traffic or excavation can weaken forage stands and create opportunities for unwanted plants to take root.



Researchers are now studying whether similar principles may apply to animal health and disease processes. For example, calves that were perfectly healthy on the farm can face a serious risk of bovine respiratory disease (BRD) in the feedlot after experiencing the stresses of weaning, commingling, transportation and ration changes. Dr. Trevor Alexander of Agriculture and Agri-Food Canada’s Lethbridge Research Station and collaborators from the University of Calgary are studying bacterial populations (the microbiota) in the respiratory tract of feedlot cattle. They published the results of a small study supported by the Beef Research Cluster earlier this year (The nasopharyngeal microbiota of beef cattle before and after transport to a feedlot; BMC Microbiology 17:70).

What they did: Little is known about what the “normal” respiratory microbiota looks like in cattle, let alone how it changes in response to any given stress. Because exposing calves to multiple stresses at the same time may have produced large, complex, difficult to interpret changes in the microbiota, this team focused on the effects of simply moving cattle from the home farm into the feedlot. They used 14 Angus x Hereford heifer calves (640 lbs) from Continue reading

5 articles for cow-calf producers heading into fall

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. To learn more about the options for internal parasite control and how to prevent resistance to dewormers:

Reduce sickness and sell more pounds
Preconditioning


By spreading out the stressors that normally occur at weaning (change in diet, vaccination, transport, etc.), calves gain more weight per dollar. Does that mean
net profits for cow-calf producers? See for yourself

Bov-Innovation: Putting Theory into Practice

This article written by Dr. Reynold Bergen, BCRC Science Director, originally appeared in the June 2016 issue of Canadian Cattlemen magazine and is reprinted on the BCRC Blog with permission of the publisher.

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.

Managing calves for improved productivity and reduced antimicrobial use: Webinar September 28

Update: Missed the webinar? Find the recording and check for future webinars on our Webinars page: http://www.beefresearch.ca/resources/webinars.cfm

The ways cow-calf producers manage their calves can have a big impact on how well they’ll perform on feed and whether they end up in the feedlot’s sick pen.

Join this free webinar for practical tips and strategies to increase fed calves’ productivity by lowering their stress and disease susceptibility. This session will also walk through the economics to help producers better understand how and when the extra efforts improve their own profitability.
