Sub-acute ruminal acidosis is a well-recognized and economically important digestive disorder in well-managed dairy cattle. It results from feeding high-grain diets to dairy cows and is characterized by daily episodes of low ruminal pH. This condition generally occurs when the ruminal pH stays between 5.2 and 6 for a prolonged period, resulting in depressed fibre digestion, rumen defaunation, reduced milk production and reduced feed efficiency. Remarkably, there are typically no clinical signs of illness in SARA-affected cows.

SARA primarily arises from the feeding practices in dairy cattle management. It occurs when cows are fed high-grain diets as part of an intensive feeding regimen or a high amount of low-fibre, high-moisture forage in free-range conditions. The excess grain consumption disrupts the balance of the rumen’s microbial ecosystem, leading to an accumulation of lactic acid and a decrease in ruminal pH. This acidic environment hinders fibre digestion and can negatively affect milk production, inverse the protein to milk fat ratio in the tank and erode the herd health. Factors such as diet composition, feeding frequency, and cow stress levels can influence the likelihood of SARA occurrence.

The consequences of SARA are multifaceted. While it may not exhibit typical clinical signs of illness, the chronic nature of SARA can lead to several detrimental effects. Reduced fibre digestion means that cows are less efficient in extracting nutrients from their diet, potentially leading to lower milk yields and increased feed costs. Furthermore, SARA can negatively impact cattle health over time, increasing the risk of secondary health issues. Therefore, managing and preventing SARA is crucial for maintaining both the economic viability and the overall well-being of dairy cattle herds.

Key Take Away Points


  • SARA is a digestive disorder primarily found in dairy cattle.
  • It results from high grain diets and prolonged low ruminal pH.
  • SARA can lead to reduced milk production and is economically significant even in well-managed dairy operations.


  • High-grain diets and imbalanced rumen ecosystems are primary causes of SARA.
  • Factors like diet composition, feeding frequency, and stress levels influence SARA risk.
  • Dairy cows, due to their specific dietary requirements, are more susceptible to SARA.


  • SARA reduces fiber digestion, leading to inefficient nutrient extraction.
  • It results in lower milk yields and increased feed costs.
  • The chronic nature of SARA can negatively affect cattle health over time, increasing the risk of secondary health issues.
