Besides being the most studied digestive disorder in cattle, ruminal acidosis still presents blind spots. The fi rst intriguing fact is individual susceptibility. If one challenges animals from same herd and similar background with a high-concentrate diet protocol, animals will present a range of ...
Further studies should be conducted to determine whether the differences in acidosis symptoms in one herd are based on behavior, physiological, microbial, or multifactorial effects. 展开 关键词:Ruminants Acidosis Sustainability DOI: 10.1007/978-81-322-2401-3_21 被引量: 27 ...
Ruminal acidosis is a well-recognized digestive disorder found in dairy cattle1. In order to maintain high milk yield, dairy cattle diets have become more nutrient-dense, containing highly fermentable carbohydrates. In some cases, this can lead to an accumulation of volatile fatty acids (VFAs) an...

Symptoms of hindgut acidosis are similar to those in subacute rumen acidosis, including reductions in nutrient digestibility, fluctuations in feed intake, and milk fat depression. Additionally, watery or foamy feces, or presence of mucin in feces indicates excessive fermentation in hindgut. With ...

In case of acute acidosis, animals present signs and symptoms of gastrointestinal disorders, anorexia and impaired general health condition. With sub-clinical acidosis, the overall health impairment is rare and animals show in the short term only a reduction of feed intake, followed in the medium/...
Subacute ruminal acidosis (SARA), characterized by low rumen pH, is one of the most important metabolic disorders in dairy cattle. As dairy cows experiencing SARA often do not exhibit overt clinical symptoms, diagnostic biomarkers in milk are of interest. Data of six acidosis induction experiments...
It is a digestive disorder indicated by symptoms that are subtle, nonexclusive, and often delayed from the time of incidence (2). Rumen pH parameters are the only reliable tools to diagnose SARA, although ruminal pH varies considerably at different locations in the rumen and during the day. ...
Reduced integrity of the barrier function can result in the translocation of endotoxins from the cell wall of Gram-negative bacteria into the portal circulation, causing inflammation-mediated liver changes and laminitis [14,21,22,23]. Other symptoms of SARA include reduced or erratic feed intake,...
