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
Relative reticulo-rumen pH indicators for subacute ruminal acidosis detection in dairy cows
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
Metagenomic assessment of the functional potential of the rumen microbiome in Holstein dairy cows
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. Read
Transient feeding of a concentrate-rich diet increases the severity of subacute ruminal acidosis in dairy cattle
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
Taxonomic Identification of Ruminal Epithelial Bacterial Diversity during Rumen Development in Goats
This research studies the development of ruminal epithelial bacteria populations and shows how they might participate in the anatomic and functional development of the rumen. Read
Presence of Selected Methanogens, Fibrolytic Bacteria, and Proteobacteria in the Gastrointestinal Tract of Neonatal Dairy Calves from Birth to 72 Hours
This article provides insight into rumen microbial colonization, which is essential for calves’ future growth and digestive health. Read
Effects of THI on health and growth performance
This study evaluated the relationship between the temperature–humidity index (THI), health and growth performance of Japanese black calves, by reviewing health data collected from nearly 20,000 calves and 60,000 markets weights. Read
Changes in digestive microbiota due to a grain-based SARA challenge
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
Transient feeding of a concentrate-rich diet increases the severity of SARA
An interesting study looking at the effect of feeding pattern on subacute ruminal acidosis (SARA) severity and rumen VFA concentrations in dairy cows. Read
New Functional DNA Microarray to Monitor Rumen Microbiota Activity
French scientists recently developed an innovative functional DNA microarray called FibroChip, which targets 392 genes involved in monitoring ruminal cellulose and hemi-cellulose degradation. Read
