Growth of breast and leg muscles and excretion of N tau methyl histidine in layer (slow growing) and broiler (fast growing) chicks were measured at five time intervals between 2 and 33 days of age. 2. The results indicate that muscles of the broiler chick grow faster than in layer chicks and that breast muscles of both strains grow faster than leg muscles in the first 2 weeks after hatching. 3. N tau methyl histidine excretion by layer chicks is higher than that by broilers relative to body weight, musculature and relative maturity at all ages examined. 4. The results suggest that faster growth of muscles is accompanied by a lower rate of protein degradation although at ages of less than 2 weeks differences in protein synthesis rates may also contribute to muscle growth.

在2至33日龄的五个时间间隔内，测量了蛋鸡（生长缓慢）和肉鸡（生长迅速）雏鸡的胸肌和腿部肌肉生长情况以及N-τ-甲基组氨酸的排泄量。2. 结果表明，肉鸡雏鸡的肌肉生长速度比蛋鸡雏鸡快，并且在孵化后的前两周，两个品系的胸肌生长速度都比腿部肌肉快。3. 在所有检测的年龄段，相对于体重、肌肉组织和相对成熟度而言，蛋鸡雏鸡的N-τ-甲基组氨酸排泄量高于肉鸡。4. 结果表明，肌肉的较快生长伴随着较低的蛋白质降解率，尽管在小于2周龄时，蛋白质合成速率的差异也可能有助于肌肉生长。
