1.试验一比较了无菌雏鸡和常规雏鸡饥饿过程中身体成分的变化。8日龄时，将无菌雏鸡分为两组，即无菌雏鸡和常规雏鸡。CVL鸟类被接种了常规饲养的鸟类的粪便。直到14日龄，这两只鸟都被随意喂食。然后挨饿6天。2.CVL鸟类在饥饿期间的氮素损失显著较低，而水分损失则相反。在两种环境中，禁食产热量是相当的。3.试验2研究了饲喂高蛋白和低蛋白饲料的雏鸡在饥饿过程中肠道微生物区系对体重和氮损失的影响。饲喂高蛋白饲料的雏鸟体重严重减轻，而饲喂低蛋白饲料的雏鸟氮损失较低。
1. Changes in body composition during starvation were compared between germ-free (GF) and conventionalized (CVL) chicks in experiment 1. At 8 days of age, the GF birds were divided into two groups, ie GF and CVL groups. The CVL birds were inoculated with faeces from conventionally reared birds. Until 14 days of age, both birds were fed a diet ad lib. and thereafter starved for 6 days. 2. Nitrogen loss during starvation was significantly lower in CVL birds, though the reverse was true for water loss. Fasting heat production was comparable between two environments. 3. Influence of the gut microflora on body weight and nitrogen losses during starvation was investigated in birds prefed diets high or low in dietary protein in experiment 2. 4. No significant effect of the gut microflora was observed in body weight and nitrogen losses. Body weight was severely reduced in birds prefed the high protein diet and nitrogen loss was lower in birds prefed the low protein diet.
