Abstract

Dairy producer increase milk production by over feeding grain diets that are high in starch and low in fiber to increase intake of energy and met dietary requirements of the high yielding dairy cows. However, these diets increase the risk of Sub Acute Ruminal Acidosis (SARA). Thus, maximizing milk production without incurring Sub-acute ruminal acidosis is a challenging most dairy producers. The main aims of this paper were to review available article on general aspects of Subacute 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. Sub-acute ruminal acidosis is a well-recognized and economically important digestive disorder found particularly in well-managed dairy cattle. It is a consequence of feeding high grain diets to dairy cows and characterized by daily episodes of low ruminal which generally occurs when ruminal pH stays in the range of 5.2 and 6 for a prolonged period resulting in depresses fiber digestion and possibly milk production. There is no typical clinical sign of illness in SARA affected cows. However, SARA is said to be associated with inflammations of different organs and tissues in dairy cows. Rumenocentesis remains the most reliable means of diagnosing SARA. The cow at risk to develop SARA includes cows in the early lactation, Primiparous cows and Cows grazing or fed with rapidly fermentable low fiber grass. SARA has long-term health and economic consequences, which include feed intake depression, fluctuations in feed intake, reduce  diet digestibility, reduced milk yield, reduced milk fat percent, gastrointestinal damage, liver abscesses and lameness. Apart from compromises to dairy cow health and economics, SARA is of concern for animal welfare reasons, since lameness and laminitis impact significantly on cow comfort and general wellbeing  Thus, it represents a significant concern for dairy industry and the cattle should be regularly monitored to facilitate early recognition of the condition and limit the associated economic losses.
