摘要

1. Two calorimetric experiments were conducted to study the utilization of energy in sheep given diets of grass silage or grass silage and barley. Three silages were investigated. One was made from first-harvest grass in the spring (S) and the others from regrowth cut either early or late in the autumn (E and L respectively). All were of perennial ryegrass (Lolium perenne) and preserved with formic acid. Each silage was given at two levels of feeding, the lower providing approximately a maintenance energy intake. The S and L silages were also given supplemented with barley.

[1。进行了两次量热实验，研究了草青贮饲料或草青贮饲料和大麦饲料中绵羊的能量利用情况。研究了三种青贮饲料。一个是春季（S）的第一季收获草，另一个是秋季早期或晚期（再次分别为E和L）。所有都是多年生黑麦草（Lolium perenne）并用甲酸保存。每个青贮饲料在两个饲喂水平下给予，下部提供大约维持能量摄入量。 S和L青少年也补充了大麦。]
