Influence of Sucrose on Rumen Fermentation Pattern and Milk Fat Content of Cows Fed a High-Grain Ration¹

Dairy Department, New Mexico State University, Las Cruces 88001

ABSTRACT

Milk fat content was not increased by replacing milo with sucrose at levels representing 5,10, and 15% of the dry matter in rations containing 10% alfalfa hay and fed in excess of National Research Council requirements. The experiment involving 16 cows was conducted in randomized block design. It consisted of a standardization period of two weeks, a transition period of four weeks, and a comparison period of sixteen weeks. During the standardization period the cows received ad libitum a ration comprised of 40% alfalfa hay (estimated net energy basis) and 60% ground milo plus minerals.

There were no significant differences among the covariant-adjusted treatment means for milk and solids-corrected milk production, milk fat, and solids-not-fat content, or production efficiency. In the rumen contents pH was lower (P<0.05) and lactate concentration was higher (P<0.10) with sucrose in the ration. The mean proportions of rumen volatile fatty acids were not significantly different among treatments.
