Bovine rumen epithelium undergoes rapid structural adaptations during grain-induced subacute ruminal acidosis.
Alterations in rumen epithelial structure and function during grain-induced subacute ruminal acidosis (SARA) are largely undescribed. In this study, four mature nonlactating dairy cattle were transitioned from a high-forage diet (HF; 0% grain) to a high-grain diet (HG; 65% grain). After feeding the HG diet for 3 wk, the cattle were transitioned back to the original HF diet, which was fed for an...
متن کاملRuminal microbial and fermentative changes associated with experimentally induced subacute acidosis in steers.
We used six ruminally cannulated steers in a two-period crossover design to study ruminal fermentative and microbial changes associated with induced subacute acidosis. Steers were adapted to either an 80% alfalfa hay (hay-adapted)- or corn grain (grain-adapted)-based concentrate diet. After feed was withheld for 24 h, steers were overfed with an all-grain diet at 3.5 x NEm daily for 3 d. Rumina...
متن کاملSubacute Ruminal Acidosis in Dairy Cattle
Ruminal acidosis is the consequence of feeding high grain diets to ruminant animals, which are adapted to digest and metabolize predominantly forage diets. Feeding diets that are progressively higher in grain tends to increase milk production, even in diets containing up to 75% concentrates. However, short-term gains in milk production are often substantially or completely negated by long term ...
متن کاملInvestigations on rumen and claw health of different wild ruminants related to subacute ruminal acidosis
In this study four ruminant species of Nuremberg Zoo were evaluated for subacute ruminal acidosis according to the feeding management. Parameters of microbiological fermentation of the rumen as well as rumen tissue samples were examined. Additionally, investigations on claw health, in terms of laminitis were made. Three of the four species, all grassand roughage feeders, showed severe character...
متن کاملImpact of Subacute Ruminal Acidosis (SARA) on Ruminal Microbiome, Lipopoly saccharide and Bioamine and Rumen Epithelial Health of Dairy Cows
Maximizing milk yield without impairing host health is a great challenge for dairy industry. However, the high concentrate feeding often unavoidably increases the risk of Subacute ruminal acidosis (SARA) in dairy cows, characterized by periodic episodes of low ruminal pH. The economic costs caused by SARA are enormous, while its pathogenesis is not very clear. As the first and the main digestiv...
