Non-antibiotic approaches to control mastitis in dairy cows

Project Details

Status: Active
Investment: $322,489
Commodity: Dairy Cattle
Organization: University of Alberta
Investigator: Burim Ametaj

Economic consequences of mastitis are related to medication of dairy cows and their culling which reach $400M CAD/year.

Why is this research important for Alberta ag?

Mastitis is one of the main diseases of dairy cows that is associated with lower milk production, alteration of milk components and lower fertility. Mastitis is one of the main reasons for culling of dairy cows in Canada. Economic consequences of mastitis are related to medication of dairy cows and their culling which reach $400M CAD/year. Most cows are treated with antibiotics and a bismuth-based sealant at dry off to prevent development of mastitis, which is a very high cost to the dairy industry and its profitability. Antibiotic use has been associated with bacterial resistance and bismuth-based sealant with residues in milk.

This research proposes to test a new intramammary infusion product made of 3 lactic acid bacteria (LAB) in a non-GMO soybean carrier enriched with nutrients for LAB. Researchers are also proposing to prepare a new sealant made of the same 3 LAB dissolved in the same carrier but in a more gel-like texture to adhere to the teat canal. Previous research has proven successful in lowering the incidence of uterine infections in dairy cows by 50% and increasing milk yield by 4L per day.

What benefits can producers expect from this research?

If this treatment works as anticipated, it will bring tremendous benefits to the dairy industry with regards to the number of cows prevented to develop disease. There will also be benefits related to increased milk production from healthier cows, lower number of culled cows, greater number of replacement heifers, and lower veterinary bills.

How will these research findings reach producers on-farm?

Researchers will work closely with Alberta Milk to ensure research results are made available to dairy producers and commercialization partners. Extension papers and fact sheets will be distributed to the industry via Milking Times, published by Alberta Milk. Results will also be shared at the Western Canadian Dairy Seminar, and published in the Western Producer.

Funded in part by the Government of Canada under the Canadian Agricultural Partnership, a federal-provincial-territorial initiative.
