Specific microbe drench may help reduce subacute ruminal acidosis

Alvaro Garcia

Highly productive dairy cows are oftentimes challenged with high grain to forage ratios. These cows are oftentimes prone to subacute ruminal acidosis (SARA) and even the clinical form (acidosis), with animal well-being implications and a negative economic impact for the farm. These changes are the result of drops in the ruminal pH as its microbial population shifts towards groups that produce more propionate, and in turn lactate. Earlier research has found that 19 % of early lactation and 26 % of mid-lactation dairy cows suffer from SARA.

Best non-invasive indicators to predict ruminal acidosis

Alvaro Garcia

Genetics of modern dairy cows require of high energy diets to maintain high production and adequate reproduction. To accomplish this highly fermentable feedstuffs are included in their rations. High starch-containing diets can oftentimes be responsible for ruminal acidosis and other associated problems that may challenge the cow’s well-being.

Using a blood marker for detecting ruminal acidosis in lactating cows

Fernando Diaz

Ruminal acidosis results from an excessive acid load in the rumen not neutralized by salivary or feed buffers. Cows susceptible to both subacute (SARA) and acute ruminal acidosis change their metabolism, eating behavior, and production performance. Measuring ruminal pH on commercial dairy farms is impracticable. Thus, developing alternative methods for identifying cows with low pH would help dairy veterinarians and nutritionists managing rumen health.
