To compare the lysine requirement of the growing germfree and conventionnal chicks, 7-day-old chicks were fed a diet with a graded levels of lysine for 7 days. Daily gains of body weight of the germfree chicks were greater than those of the conventional chicks when the dietary lysine level was higher than the requirement level. Lysine requirement for maximum growth, however, was estimated to be 0.7% of the diet for both groups. After the feeding test, chicks were injected with L-lysine-U-14C and expired carbon dioxide was collected for 2 hours. From the recovery percentage of 14C in the expired carbon dioxide, the lysine requirement was found to be 0.4% of the diet for both groups.
