Subacute 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 کاملPrevalence of subacute ruminal acidosis in some dairy herds of Khorasan Razavi province, northeast of Iran
To estimate the prevalence of subacute ruminal acidosis (SARA) in dairy cows, a total of 196 ruminalfluid samples were drawn by rumenocentesis from 10 dairy herds of Khorasan Razavi province, northeast ofIran. Two groups of 12 cows, early lactation and mid-lactation cows were sampled in each dairy herd andruminal pH was determined immediately using a portable pH-meter. A total of 54 cows (27.6%...
متن کاملShort communication: Effect of subacute ruminal acidosis on in situ fiber digestion in lactating dairy cows.
Subacute ruminal acidosis (SARA) was induced by replacing 25% of the total mixed ration intake [dry matter (DM) basis] with pellets consisting of 50% wheat and 50% barley. This reduced dietary forage content (DM basis) from 39.7 to 29.8% and increased the dietary concentrate content from 60.3 to 70.2%. Induction of SARA reduced the 24- and 48-h in situ neutral detergent fiber (NDF) degradabilit...
متن کاملSubacute ruminal acidosis: prevalence and risk factors in Greek dairy herds
Subacute ruminal acidosis (SARA) represents one of the most important metabolic subclinical disordersof high producing dairy cows, having serious impact in both animal health and herd profitability. The aim ofthis study was to confirm the presence of SARA in Greek dairy herds and record its prevalence and riskfactors. Ruminal fluid samples, via rumenocentesis, were obtained from a total of 153 ...
