After how many days postpartum are Salmonellosis infections most common in cows?

Salmonellosis infections are typically most common in cows around 10 days postpartum. This peak can be attributed to several physiological and management factors that take place shortly after calving.

After giving birth, cows undergo significant stress, both physically and immunologically. The postpartum period is marked by changes in the cow’s immune response and metabolism, which can make them more susceptible to infections. Around the 10-day mark, the transition from the higher stress of calving can start revealing underlying infections that may not have manifested immediately after birth.

Furthermore, this time frame aligns with common herd management practices where monitoring for health issues intensifies, and any latent infections, such as Salmonellosis, become evident. This knowledge is crucial for effective herd health management, allowing producers to implement preventative measures and treatments in a timely manner to reduce morbidity and improve overall herd health.
