Short 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 ...
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 کاملSubacute Ruminal Acidosis and Evaluation of Blood Gas Analysis in Dairy Cow
Subacute Ruminal Acidosis (SARA) corresponds to an imbalance between lactate-producing bacteria and lactate-using bacteria, which results in a change in ruminal pH associated with a prevalent consumption of rapidly fermentable carbohydrates. In our study, 216 primiparus and multiparus dairy cows were selected from 20 Italian intensive dairy herds and were divided into three groups based on the ...
متن کاملEffects of feeding buffering mineral mixture on subacute rumen acidosis and some production traits in dairy cows.
This trial was designed in order to evaluate the incidence of subacute rumen acidosis (SARA) during early lactation and to investigate the possibilities for its prevention by use of a buffering mineral mixture. On the beginning of the trial it was found that the pH value of rumen fluid in 4 animals was lower than normal (pH < 6.0) and that 20% of animals have had SARA. The control and the exper...
