With 10% to 35% of cows experiencing mastitis each lactation, grappling with its cost is a reality of milking cows. A Canadian study showed mastitis costs dairy farmers roughly $660 per cow per year, making it the costliest disease of dairy cattle.

Cases began to appear more frequently from 2021 onward, as Chilliwack, British Columbia-based veterinarian John Dick began witnessing more cattle infected with S. Dublin in his clients’ herds, noticing that clinical signs varied markedly from the clinical signs typically present in other salmonella serotypes.

The immune system is the body’s military. It is tasked with being able to recognize pathogenic invaders that have entered the body and eliminate them as quickly as possible.

A productive cow isn’t always a profitable cow. A profitable cow performs in milk volume and quality, breeds back quickly and experiences few health events.
