Chicks of a heavy-bodied strain were deprived of food on alternate days from 14 to 83 days of age. Relative food intake was depressed by intermittent feeding to 25 days of age, after which the deprived chicks resumed the relative intake of the ad libitum-fed controls, i.e., the relative intake on repletion day was twice that of the control chicks. Following an adaptation period of 2 weeks, the relative growth rate of the intermittently fed chicks exceeded that of the control group, the excessive growth being due to an increase on the day of repletion which was more than twice that of the control birds. Body fat concentration was depressed by intermittent feeding throughout the experimental period. Although, in ad libitum-fed chicks, periodical deposition of body protein and fat was parallel throughout the experimental period, in the treated chicks, protein deposition prevailed initially and fat deposition prevailed at the end of the experimental period. Intermittent feeding was accompanied by a consistent increase in the relative weight of the liver, pancreas, and gastrointestinal tract, including the small intestine. The differences in food intake, growth, body composition, and gastro-intestinal tract between heavy- and light-breed chicks exposed to intermittent feeding are discussed.
对一种重型品系的雏鸡从14日龄至83日龄隔日禁食。到25日龄时，间歇性喂食使相对采食量降低，之后禁食的雏鸡恢复到自由采食对照组的相对采食量，即饱食日的相对采食量是对照雏鸡的两倍。经过2周的适应期后，间歇性喂食的雏鸡的相对生长率超过了对照组，过度生长是由于饱食日的增长超过对照鸡的两倍多。在整个实验期间，间歇性喂食使体脂浓度降低。尽管在自由采食的雏鸡中，整个实验期间体蛋白和脂肪的周期性沉积是平行的，但在处理过的雏鸡中，最初蛋白质沉积占优势，在实验期结束时脂肪沉积占优势。间歇性喂食伴随着肝脏、胰腺和包括小肠在内的胃肠道相对重量的持续增加。讨论了重型和轻型品种雏鸡在间歇性喂食情况下采食量、生长、身体组成和胃肠道的差异。
