- •
Changes in reticular pH during the close-up period in dairy cows were monitored.
- •
SARA cows in the period had typical pH profiles compared to non-SARA cows.
- •
The effects of yeast supplementation on reducing the risk of SARA were also evaluated.
- •
Yeast supplementation did not prevent the postpartum decrease in reticular pH.
