Ruminal acidosis is a common disease in high yielding dairy cows, during which the rumen pH is depressed for several hours per day. There is no general agreement of the definition of the disease, and its diagnosis based on rumen pH measurement is invasive and inaccurate. As a result, the disease often goes unnoticed, and its impact is not well recognized. Surveys suggest a prevalence of between 19 and 26% in early and mid-lactation dairy cows in North America. Many symptoms have been attributed… Expand
Subacute ruminal acidosis in dairy cows - physiological background, risk factors and diagnostic methods
TLDR
Based on the existing literature, rumenocentesis and the use of an oral stomach tube are reliable field techniques to detect SARA and Wireless indwelling pH probes may become important tools for the continuous measurement of ruminal pH in the coming years. Expand
Sub-acute Ruminal Acidosis (SARA) and its Consequence in Dairy Cattle: A Review of Past and Recent Research at Global Prospective
TLDR
This paper reviewed available article on general aspects of Sub-acute ruminal acidosis and its consequence in dairy cattle by focusing on past and recent article and helping to update the current knowledge for early recognition and limit the associated negative impact in dairy industry. Expand
Biomarkers from automatic milking system as an indicator of subclinical acidosis and subclinical ketosis in fresh dairy cows.
TLDR
According to these results, some biomarkers from the AMS have an association with SARA and SCK, however, further research with a higher number of cows is needed to confirm this conclusion. Expand
The effect of calcareous marine algae, with or without marine magnesium oxide, and sodium bicarbonate on rumen pH and milk production in mid-lactation dairy cows.
TLDR
Results indicate that the addition of CMA can benefit milk fat and protein production when included in diets based on typical feedstuffs of the northern European region. Expand
Improving milk nutritional value and processing properties through giving feed supplements to highly productive cows
Currently, it has been understudied which forms of feed supplements ensure the most positive effect on increasing milk nutritional value and processing properties. In this regard, an experiment wasExpand

Subacute ruminal acidosis in dairy cows: the physiological causes, incidence and consequences.
TLDR
Increases in acute phase proteins vary among methods of SARA induction, even when the methods result in similar rumen pH depressions, suggesting that the inflammatory response might not be solely due to bacterial endotoxin in the rumen. Expand
Understanding and preventing subacute ruminal acidosis in dairy herds: A review
Abstract Feeding diets high in grain and other highly fermentable carbohydrates to dairy cows increases milk production, but also increases the risk of subacute ruminal acidosis (SARA). SARA isExpand
Ruminal acidosis in beef cattle: the current microbiological and nutritional outlook.
TLDR
Optimal model systems for assessing effects of various management and nutritional strategies on ruminal acidosis will require technologies that allow feed intake patterns, ruminal conditions, and animal health and performance to be measured simultaneously in a large number of cattle managed under conditions similar to commercial feed yards. Expand
Acidosis in cattle: a review.
TLDR
Continued research concerning grain processing, dietary cation-anion balance, narrow-spectrum antibiotics, glucose or lactate utilizing microbes, and feeding management (limit or program feeding) should yield new methods for reducing the incidence of acute and chronic acidosis. Expand
Subacute Ruminal Acidosis and Evaluation of Blood Gas Analysis in Dairy Cow
TLDR
Results indicate that blood gas analysis is a valuable tool to diagnose acidosis in dairy cows because it provides good assessment of acidosis while being less invasive than rumen pH analysis. Expand
Feeding to Minimize Aciodosis and Laminitis in Dairy Cows
Introduction Sub-acute rumen acidosis (SARA) is a prevalent problem for dairy herds (Cook et al., 2004; Nordlund et al., 2004) as characterized by having more than 25% of cows sampled viaExpand
Nutritional Approaches to Minimize Subacute Ruminal Acidosis and Laminitis in Dairy Cattle
TLDR
Both the nutritionist and dairy managers are responsible for the delivery and consumption of a ration that is likely to produce a ruminally healthy pH, and nutritionists should consider the expected amount of physically effective neutral detergent fiber provided by ration ingredients. Expand
An Evaluation of Parameters for the Detection of Subclinical Rumen Acidosis in Dairy Herds
TLDR
The present study revealed some limitations of the rumenocentesis technique in small or medium-sized herds due to difficulties in selecting sufficient numbers of cows in the respective groups at risk, and monitoring of dairy herds for SRA should be performed routinely. Expand
Subacute ruminal acidosis (SARA) in grazing Irish dairy cows.
TLDR
The study showed that low rumen pH is prevalent in grazing Irish dairy cattle consuming perennial rye grass-based pasture and raises concerns regarding effective pasture utilisation and possible consequences for animal health. Expand
Subacute rumen acidosis in lactating cows: an investigation in intensive Italian dairy herds.
TLDR
The results indicated the presence of SARA in three herds, a critical situation in five farms and a normal rumen pH condition in two herds, and animal management seems to be one of the most important factors in developing SARA including total mixed ration preparation. Expand
