Abstract
A 100-day metabolism study with 40 ruminally cannulated steers, individually fed, was conducted to determine the efects of daily feeding of encapsulated Megasphaera elsdenii along with a one-time dose of Lactipro NXT on dry matter intake, rumen organic acid concentration, lactate disappearance and native and specific strains of Megasphaera elsdenii concentration following an acidosis challenge. Steers fed Megasphaera elsdenii daily had greater intake after an acidosis event. Cattle fed daily Megasphaera elsdenii also had a faster rate of lactic acid disappearance after an acidosis event. Feeding Megasphaeara elsdenii daily may result in a faster recovery time, after an acidosis event, comapred to a one-time drench of Megaspharea elsdenii.
