Detect Sub-Acute Ruminal Acidosis

Sub-Acute Ruminal Acidosis (SARA) usually causes a decrease in milk fat production. A drop in fat content in a large number of cows in a group, usually points to a problem with their feeding ration preparation, such as:

  • Over-mixing or over-processing of the TMR that reduces particle size and eNDF content.

  • Minimized separation of feed ingredients during TMR mixing and delivery.

  • When feeding a TMR, monitor and minimize sorting in the feed bunk.

  • Inadequate length of cut for forages and silage.

A red SARA Suspicion – Session alert is displayed when:

  • More than 10% of cows experience a drop in fat %.

  • The fat/protein ratio for the group drops to <1.0.
