Abstract: Determining the requirement of crude protein and crude fiber in thematural-ingredient diet guinea- pig at first . Then determining theformule of fortified pelleted diet for the breeding guinea-pig accordingto aboverequirement .The reproductivity of the guinea-pigcolony byfeeding the fortifed peleted diet and autoclaved hay instead of green food is superior to the reproductivity of control animals . Realizing our ultimate aim of discontinu-ing the feeding of green food as a supplement to the breeding guinea-pigs .

Key words: guinea-pig, fortified peleted diet.

摘要： 本试验首先确定繁殖豚鼠在天然组分日粮状态下对粗蛋白质和粗纤维的需要量，然后根据此需要量制定豚鼠强化营养颗粒饲料配方构成。用此强化营养颗粒饲料加消毒干草取代青饲料饲喂繁殖豚鼠，获得优于或等同于对照组动物的各项生产指标，实现了繁殖豚鼠饲料脱青的目标。
