The Effect of Added Fiber With and Without Fat in a Practical Broiler Ration

Abstract

ABSTRACT THE emphasis in recent years on broiler rations of high energy content has resulted in very little use of medium and low energy feeds. The present availability of a concentrated energy source such as inedible animal fats is such that these fats might be profitably combined with low energy feeds for use in broiler rations provided the only limiting factor in their use is low energy content. Insko and Culton (1949) compared the effect of ground oats, alfalfa meal, and wheat bran added alone and in various combinations to starter rations on an equal fiber basis. Maximum growth rate was obtained from rations containing less than 5% fiber, regardless of its source. Robertson et al. (1948) reported that a chick ration containing 3.5% crude fiber and 800 Calories per pound of productive energy promoted faster growth in White Leghorns than rations which were lower in productive energy but equal in . . .
