The control of egg production using a low‐sodium diet

Synopsis

Experiments have shown that egg production can be controlled by using a low‐sodium diet. When a diet containing 0.038% sodium was fed to birds prior to point of lay, egg production was severely restricted. When this diet was fed to hens already in lay, production ceased but the subsequent feeding of an adequate diet resulted in rapid re‐attainment of production to a level higher than that of normally‐fed birds. There were also improvements in egg and shell quality. Birds fed on the low‐sodium diet remained in good condition and mortality did not increase.
