Abstract

Subacute ruminal acidosis'(SARA) is a common health and productions problem in dairy cattle and described as repeated incidences of drop pH. of the rumen. The aim of the study was to estimate the lipopolysaccharide concentration in the content of ruminal fluid and feces of dairy cows as a diagnostic tool for subacute ruminal acidosis. Four hundred and twenty- seven cows examined in this study in Al-Qadisiyah Province, from these cows, Ninety lactating cows, were have affected with subacute ruminal acidosis. Moreover, fifty healthy lactating cows were considered as a control. Both diseased and control cows were exposed to additional tests of ruminal fluid and fecal samples. The difference observed in the lipopolysaccharide (LPS) concentration in the ruminal fluid and fecal samples 97.772 and 108.823 Eu/ml respectively, of SARA group which were significantly (P≤0.05) higher than the control group. The ruminal and fecal LPS can be used as diagnostic tools to identify the SARA.
