Sodium Requirement for Broiler Breeder Hens
Poultry Science, 1995 Two experiments were conducted with Arbor Acres hens to determine their Na requirement. Sodium chloride was added to a corn-soybean meal diet to furnish daily intakes of 35, 65, 95, 125, and 150 mg per hen in Experiment 1. The 150 mg level was replaced with 180 mg in Experiment 2. The hens were maintained in floor pens with wood shavings used as litter.

Copper requirements of broiler breeder hens
Poultry Science, 2018 One-hundred-twenty Cobb 500 hens, 20 wk of age, were randomly allocated into individual cages with the objective of estimating Cu requirements. After being fed a Cu deficient diet for 4 wk, hens were fed diets with graded increments of supplemental Cu (0.0; 3.5; 7.0; 10.5; 14; and 17.5 ppm) from Cu sulfate (CuSO4 5H2O), totaling 2.67; 5.82; 9.38; 12.92;
