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.

Gut capacity of broiler breeder hens
British Poultry Science, 2021 1. Broiler breeders are subjected to qualitative or quantitative feed restrictions to prevent obesity, which causes major health and welfare problems. Diluting their feed by adding inert or low nutrient, bulky materials can reduce obesity, but the capacity of the gut needs to be determined to apply this strategy successfully.

Studies on the Biotin Requirement of Broiler Breeders ,
Poultry Science, 1972 Abstract The minimum requirement of biotin for maximum hatchability of eggs and livability of chicks was determined for broiler breeder hens maintained in individual cages. Groups of hens were fed casein-gelatin, glucose diets containing 20, 40, 60, 100, 180 and 340 μg. biotin/kg. of diet. The requirement was found to be approximately 100 μg.
