Study on dairy cows maintained in various dairy farms in and around Shivamogga on different feeding pattern was taken up to determine risk indicators associated with Sub-acute ruminal acidosis (SARA). The presence of SARA in dairy cows was identified by measuring pH of rumen liquor falling within a range of 5.2 to 5.9. The prevalence was found to be 19.61 per cent. Risk indicators identified are laminitis, lowered milk fat and fat to protein ratio, loose faecal consistency and coarse faecal structure and rumen fluid parameters such as type of protozoa, proportion of live to dead and iodophilic activity. Univariate analysis of laminitis was found to be significantly influencing risk indicator of SARA (p=0.020). Analysis of milk fat percentage revealed its significant association with the SARA (p=0.002). Analysis of milk fat: protein ratio in SARA positive cattle indicated that the ratio is significant indicator of SARA (p=0.004). Fecal structure and fecal consistency of cows found was to be a significant indicator of SARA (p=0.000). The proportion of cows with a greater number of small sized protozoa showed a positive significant indicator of SARA (p=0.035). Protozoa grouped as live (not having dead protozoa), few dead and more dead under microscopic examination for finding the proportion of these groups of protozoa among SARA positive cows which revealed a significant indicator (p=0.013). The iodophilic activity of protozoa was found to be a significant indicator of SARA (p=0.027). Iodophilic activity of SARA affected cattle in the present study was found to be nil to moderate.
