Sodium requirement of the turkey hen

Two experiments were conducted to determine the sodium requirement of the Large White turkey hen. A supplementation rate of 0.59 g sodium/kg diet (1.0 g sodium/kg in total) was required for maximum production when the hens were fed a maize-soyabean meal diet. The egg production of hens receiving a diet without added sodium had fallen to zero after 70 d. After 1.18 g sodium/kg was added to the diet 40% of hens returned to production within 14 d.
