9.7 Effect of Ensiling on the Release of Soluble Carbohydrates and Nitrogen During Eating and its Relationship to Intake and Nitrogen Retention

Abstract

The object of the experiment to be reported was to determine the extent to which intake and eating behaviour are influenced by differences in the ratio of nitrogen (N) to water soluble carbohydrates (WSC) in the feed and the liquid phase of boli obtained from oesophageal fistulae. Four feeds were chosen as being likely to cover a range of N to WSC ratios in the liquid phase; these were frozen lucerne, lucerne silage, grass silage and grass silage treated with formaldehyde (46 g/100 g crude protein).
