Several previous work has shown that accelerated milk replacer (MR) programs reduce starter intake and therefore,affect the ruminal pH and NH3-N concentration in preweaning period, but there is limited work that evaluates the effect of varyingboth the pre- and postweaning feeding program. The aim of this study was to evaluate whether the amount of milk replacer andpostweaning feeding level affect ruminal environment around the weaning period
