Effects of food restriction on growth rate and relative growth rates of supply organs (liver, heart, lungs and kidneys, digestive tract) and demand organs (breast, back, thighs, abdominal fat) of broiler chickens were studied. 2. Birds were restricted in intake to 50% (group FI 50) or 75% (group FI 75) of ad libitum from 5 to 11 d of age; all birds were fed ad libitum from 12 to 39 d of age. 3. Relative growth rates from 12 to 39 d of age of group FI 50 were higher (P < 0.05) than group FI 75 and control group. 4. No significant differences in food conversion ratio, carcase fat and abdominal fat between groups were observed. 5. At 12 d of age, relative weight of the empty digestive tract of group FI 50 was higher (P < 0.05) than that of the control group and group FI 75. 6. The increased weight of the empty digestive tract may have contributed to the ability of the chickens to achieve compensatory growth after the restriction period.

研究了限饲对肉鸡供应器官（肝脏、心脏、肺、肾脏、消化道）和需求器官（胸肌、背部、大腿、腹部脂肪）生长速率及相对生长速率的影响。2. 从5日龄至11日龄，将鸡的采食量限制为自由采食的50%（FI 50组）或75%（FI 75组）；所有鸡从12日龄至39日龄自由采食。3. FI 50组12日龄至39日龄的相对生长速率高于FI 75组和对照组（P < 0.05）。4. 各组之间在饲料转化率、胴体脂肪和腹部脂肪方面未观察到显著差异。5. 在12日龄时，FI 50组空消化道的相对重量高于对照组和FI 75组（P < 0.05）。6. 空消化道重量的增加可能有助于鸡在限饲期后实现补偿生长的能力。
