Abstract

Four cannulated dairy cows in early lactation were offered grass-silage-based diets, designed to contain either 20 or 30% starch or sucroseon a DM basis, in a 4 x 4 Latin square design. In order that the diets had the same fibre content, pure wheat starch and pure sucrose were utilized. No differences were found for digestion and passage rates ofNDF, determined by the rumen evacuation technique, when the lower proportion of either starch or sucrose was used in the diet. With the higher proportion of starch in the diet, the rate of digestion decreased,but rate of passage also decreased and consequently rumen digestibility of NDF did not change. With the higher proportion of sucrose in thediet, rate of digestion also decreased, but more markedly than with starch, and at the same time passage rate increased, resulting in a marked decrease in rumen digestibility of NDF.
