Sub Acute Ruminal Acidosis (SARA) is induced by high concentrations of short-chain fatty acids (SCFA) that result in lower ruminal pH and damage to the epithelial barrier function. The present study investigated if SCFA directly contribute to epithelial barrier failure.

Cows with Sub Acute Ruminal Acidosis (SARA) are more susceptible to other health challenges than healthy cows. This study showed differences in fever symptoms, DMI and even chewing activity were more pronounced in SARA cows compared to healthy animals.

Sub Acute Ruminal Acidosis (SARA) is defined as a drop in rumen pH, but what is the most accurate way to look at these pH variations? This study addressed this important research question and even accounted for individual variabilities.

Milk yields are different between the first and subsequent lactations. This fact led researchers to investigate if there was also a difference in rumen microbiota.

Rumen health is affected by what is fed — and also how its fed. This study shows the relationship between patterns of concentrate-rich feeding and the severity of Sub Acute Ruminal Acidosis (SARA) and rumen VFAs profiles.

A study showing how a grain-based diet-induced subacute ruminal acidosis (SARA) challenge impacts the rumen microbiota of lactating dairy cows. The richness, the diversity, as well as the stability of the bacterial communities were reduced for SARA challenged cows. Both ruminal and fecal microbiota were changed, indicating that the rumen but also the hindgut microbiota are affected by SARA challenge.
