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. Read

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. Read

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. Read

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. Read

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. Read

An interesting study looking at the effect of feeding pattern on subacute ruminal acidosis (SARA) severity and rumen VFA concentrations in dairy cows. Read

Subacute ruminal acidosis affects fermentation and endotoxin concentration in the rumen and relative expression of the CD14/TLR4/MD2 genes involved in lipopolysaccharide systemic immune response in dairy cows Read

Feeding management factors have great potential to influence activity patterns and feeding behavior of dairy cows. Read

A study that demonstrates the importance of feeding management for lactating dairy cows. Read

High-producing, mid-lactation dairy cows are not equally susceptible to sub acture ruminal acidosis (SARA) fed a high-grain diet. Read
