Regulation of Food Intake in Ruminants. 6. Influence of Caloric Density of Pelleted Rations

摘要: Abstract The objectives of this experiment were to determine voluntary feed and energy intake rations varying in digestibility density describe on which is limited by fill. A basic concentrate mixture was diluted from 5 50% at 5% increments with each four diluents: (A) oak sawdust, (B) sawdust constant 3% kaolin clay, (C) verxite, an expanded hydrobiotite, (D) as (A), except nitrogen kept 17.4% crude protein equivalent. Thus, 40 evaluated. pelleted. Each ration sequence (A–D) fed sheep maintained metabolism stalls. Density the measured a dry basis water displacement. Dry matter (g/W kg .75 ) increased digestible per gram 2.5kcal for Ration Sequences A, B, D. With having values above 2.5 kcal/g, decreased (kcal/W remained static. Apparently, fill these when less than whereas level regulated. Comparable caloric 1.45 kcal/ml (based density) 3.48 displacement density). rejected C 3.0 kcal/g (greater 15% verxite), possibly because unpalatable.
