چکیده
To estimate the prevalence of subacute ruminal acidosis (SARA) in dairy cows, a total of 196 ruminal
fluid samples were drawn by rumenocentesis from 10 dairy herds of Khorasan Razavi province, northeast of
Iran. Two groups of 12 cows, early lactation and mid-lactation cows were sampled in each dairy herd and
ruminal pH was determined immediately using a portable pH-meter. A total of 54 cows (27.6%) were found
to be experiencing SARA. No significant differences were found between SARA affected and non-affected
cows in ruminal contractions, faecal quality and fat and protein components of milk.
