Ruminant parasite drugs are a precious tool — here’s how to use them

Rotating drugs, underdosing, and overtreating can lead to drug resistance in ruminants, says expert

By
There’s no denying it — drugs used to treat parasites in sheep and goat production need to be employed properly. If they’re not, that could lead to parasitic resistance and drugs that just don’t work. “You can’t just hammer drugs at the problem, because they won’t work forever,” said Lynn Tait, a sheep producer and […] Read more

Producers careful with antimicrobials, survey finds

Only 20 per cent of those surveyed ever used antimicrobials 
important in human medicine, but some resistance was found

By
Cow-calf producers are being careful with antimicrobials — and that’s a good news story the industry needs to share with consumers, says one of the researchers of a groundbreaking study of cattle production on the Prairies. The cattle health network, which has been tracking production practices of more than 100 cow-calf producers since 2012, found […] Read more

Bacteria share antibiotic resistance with genetic partners

By
Michigan State University researchers have uncovered a troubling trend towards multiple antibiotic resistance in concentrated animal feeding operations. A research team led by James Tiedje, distinguished professor of microbiology found that in large swine farms where antibiotics are used continuously in feed for growth promotion and disease prevention, multi-drug-resistant bacteria are likely the norm rather […] Read more

Antibiotic resistance threat can’t be dismissed, say experts

Antibiotic use in cattle doesn’t appear to be a threat 
to human medicines, but their use must still be curbed

By
Despite intense scrutiny, there’s little evidence that antibiotic use in the cattle industry is increasing resistance to human medicines. But it could be causing increased resistance to antibiotics used to treat cattle, say two experts. There’s no question that using antibiotics increases the odds of bacteria becoming resistant, said Reynold Bergen, science director of the […] Read more

Livestock drug use back in the spotlight

New ‘superbug’ gene has alarm bells ringing around world and 
will likely mean more oversight of antimicrobials here

By
The discovery that a much feared “superbug” gene has somehow crossed the border into Canada is increasing calls for more oversight of on-farm antibiotic and antimicrobial use. The new gene, called MCR-1, makes bacteria immune to a group of antibiotics used as the last defence to fight resistant bugs. MCR-1 was confirmed to have surfaced […] Read more
