Synopsis
With pullet chicks during the first 8 weeks of life there were no significant advantages in mortality, growth, feed consumption or in the efficiency of the conversion of food to live‐weight through supplementing a basal diet composed of feeding stuffs of plant origin with inorganic phosphorus.
During the period 8–18 weeks the results showed a similar pattern. The birds in all groups grew satisfactorily and appeared normal. No consistent or significant differences occurred between the rearing groups in mortality, growth, food consumption of feed efficiency.
The results of the present experiments provide further confirmation that pullet chicks can be reared satisfactorily to 18 weeks of age on diets containing neither animal protein nor phosphorus supplements.
