Abstract
LOW LEVELS of dietary protein have been found to delay sexual maturity in pullets (Waldroup and Harms, 1962). Arscott and Parker (1963) stated that adult males fed 6.9% protein had higher fertility than the males fed 10.7% or 16.0% protein; there was no effect on hatchability. Wilson et al. (1965) found that body growth was inversely related to the level of dietary protein when levels of 16.0, 9.0, 6.75 and 4.5% were fed during the growing period. Sexual maturity was delayed in the low protein groups, but after being fed a 17.0% protein diet for 7 weeks sperm concentrations were about equal in all groups. Fertility was higher in the males which had been fed 9.0 and 6.75% protein during the growing period. Hatchability of fertile eggs was not affected by the level of protein fed.The following experiments were designed to study the effects of low dietary protein during .
