The Highly Digestible Fiber for Dairy Rations

NutriFiber is a forage grass technology, available in select Barenbrug grasses, that helps modern dairy producers by providing physically effective, digestible fiber for today’s high producing cows. Today’s high-producing dairy cows require both Non-Fiber Carbohydrate (NFC) and Neutral Detergent Fiber (NDF). Properly balancing NFC and NDF is critical for animal health and profitable production. Table 1 below presents ration guidelines.

Rumen acidosis is a metabolic disease of cattle, occurring when the pH of the rumen falls to less than 5.5 (normal range is 6.5 to 7.0). Like most metabolic diseases for every cow that shows clinical signs, there will be several more which are affected sub-clinically. The primary cause of acidosis is feeding a high level of rapidly digestible water-soluble carbohydrate. Acute acidosis often results in death. A milder form, called Subacute Ruminal Acidosis (SARA), is seen in dairy cattle. 


SARA: Subacute Ruminal Acidosis 

Extended periods of ruminal pH below 5.5-5.6 

Reduced feed intake 

Transient diarrhea 

Reduced milk production and butter fat 

Poor immune function 



Feeding NutriFiber forages, with more digestible physically effective fiber than wheat straw, can help to reduce acidosis.

"Acidosis is the most important nutritional problem that feedlots face daily and is a major challenge for dairies as well."1 [it is] “Caused by a rapid production and absorption of acids from the rumen when cattle consume too much starch (primarily grain) or sugar in a short period of time, acidosis causes cattle to be stressed. As long as cattle are finished on grain, cows are grazed on cornstalk fields (grain consumption) or high energy (grain) diets are fed to dairy cows, acidosis will be an important problem."2


"... grains are subject to microbial fermentation in the rumino-reticulum part of the stomach complex. ... The microbial fermentation of starches contained in grains can proceed too rapidly causing the rumen to become acidotic. The severity of the acidosis may range from mild to life threatening."1
