摘要: 1. Body composition was determined in 9‐week‐old chickens sampled from four lines selected either for increased body‐weight gain (line W), food consumption F), decreased conversion ratio E), or at random C), after three, and five generations of selection. 2. After selection the proportions carcass water (678 g/kg) protein (187 were highest line E lowest (636, 180 g/kg respectively) F. The proportion fat (83 (134 3. Lines W C similar intermediate to F all constituents. 4. There more females (115 vs 98 less (177 190 (652 665 than males. 5. Line differences not appreciably altered if birds killed equal weight rather age.
