Thirty-four lactating dairy cows were allotted to two groups based on previous lactation mature equivalent 305-d milk production (average 30 and 23 kg/d) and assigned randomly to four dietary treatments. Diets with slow (high fill) or fast (low fill)

Continuous culture fermentations were conducted to determine the effect of pH and digesta flow rates on fermentation of a 65% grain, 35% forage ration by rumen microorganisms. The pH selected were 5.8, 6.2, 6.6, and 7.0. Imposed on each pH in a rando
