Abstract: Current Insights Regarding the Role of Farm Animals in the Spread of Antimicrobial Resistance from a One Health Perspective

Oct 21, 2022

Antimicrobial resistance (AMR) represents a global threat to both human and animal health and has received increasing attention over the years from different stakeholders. Certain AMR bacteria circulate between humans, animals, and the environment, while AMR genes can be found in all ecosystems. The aim of the present review was to provide an overview of antimicrobial use in food-producing animals and to document the current status of the role of farm animals in the spread of AMR to humans. The available body of scientific evidence supported the notion that restricted use of antimicrobials in farm animals was effective in reducing AMR in livestock and, in some cases, in humans. However, most recent studies have reported that livestock have little contribution to the acquisition of AMR bacteria and/or AMR genes by humans. Overall, strategies applied on farms that target the reduction of all antimicrobials are recommended, as these are apparently associated with notable reduction in AMR (avoiding co-resistance between antimicrobials).

Video: Selling Hay for 40 Years: Fritz Trauttmansdorff, Dunlea Farms

Fritz Trauttmansdorff came to Canada from Austria in 1980, bought a 45-cow dairy farm at Jerseyville, and within two years had more hay than he knew what to do with. He sold the quota in 1986, went debt-free, and built a hay business that has kept some of the same customers for forty years. Today Dunlea Farms runs about 2,500 acres — roughly 600 of it hay, the rest IP soybeans and grain corn — and Fritz makes the case that hay isn't the crop you grow when grain doesn't work. It's the crop that makes the grain work.

"If you grow corn, soybeans and wheat, you're on a three-wheeler. If you put hay in the rotation, you're on a four-wheeler."

WHAT WE COVER • Why the hay market moves independently of the Chicago Board — and what that does for farm-level risk
• The real cost of a mistake: five bushels in grain, versus the whole crop in hay
• Getting a second job out of the same iron — planting tractors that mow all summer, tillage tractors that bale
• How a grain farmer can get hay into the rotation without buying a single piece of hay equipment
• Drilling Timothy in the fall and double-cropping soybeans into it the next June
• What it actually takes to go all-in: roughly 500 acres, good sheds, and a baler you didn't buy used
• Local, regional and international hay markets — and choosing which one you're building for
• Why 40-year customer relationships are the asset, not the equipment
