Bleeding induced alterations in ruminal fluid contents

Abstract

The effect of 20% bleeding on ruminal fluid contribution, ruminal water kinetics and electrolytes and biochemical profile was studied in calves. Ruminal fluid pH, buffering capacity, total protein nitrogen, sodium, chloride, rumen volume, dilution rate, flow rate per hour and total fluid out flow rate per 24 hr (TFOR) decreased initially and recovered there after in control group. The rumen volume, dilyiion rate, flow rate per hour and TFOR per 24 hr increased in hypotonic and oil emulsion isotonic infusion groups. Total volatile fatty acids (TVFA) concentration in control and hypotonic infusion groups increased postinfusion.
