How to get new feedlot calves settled and gaining quickly; advice from producers, veterinarians and feedlot consultants

Getting calves settled, keeping them healthy and getting them gaining involves serious management that considers many variables. A successful program to keep these calves healthy and growing should involve co-operative consultation between the feeder, herd health veterinarian and the livestock nutritionist. Stress on calves is the number one offender and the degree of stress can vary widely between calves and loads of calves. If not managed properly, freshly weaned calves heading to a feed yard can be very susceptible to pneumonia and other illnesses.

While herd health veterinarians and feedlot production specialists can each have slightly different approaches to getting new feeders ramped up to the intended full-feed ration, all have a common starting point — get calves unloaded into a receiving pen, don’t over crowd them, make sure they have access to good quality grass hay, are drinking water, the lot is well bedded, and the cattle get a few hours of rest before processing.

It sounds like a simple enough plan when introducing newly weaned calves to the feed yard. But, to successfully get calves eating and gaining, ideally from day one, takes both planning and management. Continue reading

Does Antibiotic Resistance Move Through the Environment?

Recent columns have talked about antibiotic use in Canadian cow-calf and feedlot operations. Contrary to common misconceptions, antibiotic resistant bacteria are very unlikely to transfer from cattle to beef, evade food safety interventions in the processing plant, survive cooking, and cause an antibiotic resistant infection in a person. But can antibiotic resistant bacteria be transmitted from cattle, through feedlot manure and runoff, across soil, through wetlands, streams and rivers, and reach humans through the environment?

A Beef Science Cluster study led by Dr. Rahat Zaheer and Tim McAllister of Agriculture and Agri-Food Canada (with collaborators from the Public Health Agency of Canada, the University of Calgary’s faculties of medicine and veterinary medicine, University of Guelph, Alberta Agriculture and Feedlot Health Management Services) examined this question.

What they did: This research focused on bacteria called enterococci that can cause infections in humans (e.g. urinary tract, liver and bile duct, heart, surgery wound, and bloodstream infections). Most enterococcal infections can be effectively treated with macrolide antibiotics. This is important because macrolides (products like Draxxin, Zuprevo, Micotil, Tylan, Zactran, etc.) are commonly used in both beef production and human medicine.

Over a two-year period, this team collected samples from feedlots (pen floor fecal samples, collection ponds, stockpiled and composted manure), agricultural soils, wetlands, streams, municipal sewage, packing plants, retail meats and human patients. Advanced lab testing was used to identify the specific types of enterococci and antibiotic resistance patterns in the samples from each location.

Antibiotic Use in Canadian Feedlots

This article written by Dr. Reynold Bergen, BCRC Science Director, originally appeared in the October 22, 2018 issue of Canadian Cattlemen magazine and is reprinted on the BCRC Blog with permission of the publisher.



September’s column summarized a Beef Cluster project that evaluated antibiotic use in Western Canadian cow-calf operations. Nearly all cow-calf farms used antibiotics, but very few animals were treated, and most of the antibiotics used were not related to the antibiotics most commonly used in humans. But when it comes to antibiotic use in the beef industry, most of the attention is focused on the feedlot sector.

Until recently, the best Canadian feedlot antibiotic use information came from a small 2006 project (Antimicrobial Resistance in Escherichia coli Recovered from Feedlot Cattle and Associations with Antimicrobial Use, PLoS ONE 10: e0143995). Antibiotic use practices change over time, so a Beef Science Cluster 2 project updated and expanded this knowledge. Continue reading
