Expert says prepare to raise beef in a world without growth promotants

While there’s no question beta-agonists and antibiotics work,

New limits on antimicrobials won’t be too restrictive, says Alberta rancher and CCA president Dave Solverson.

Health Canada pushing to end of routine use of antibiotics important in human medicine because of resistance threat

Health Canada’s move to end the use of “medically important” antibiotics as growth promotants won’t hurt livestock production, say an Alberta producer and industry experts. “There won’t be as much restriction as we first thought,” said Camrose rancher and Canadian Cattle Association president Dave Solverson. “(But) there will be a little more consultation with veterinarians […] Read more
