prevalence of subacute ruminal acidosis in some dairy herds of khorasan razavi province, northeast of iran
Authors
abstract
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%) were foundto be experiencing sara. no significant differences were found between sara affected and non-affectedcows in ruminal contractions, faecal quality and fat and protein components of milk.
