The Chloride Requirement of the Broiler Breeder Hen
Poultry Science, 1984 An experiment was conducted to determine the chloride requirement of broiler breeder hens fed a corn soybean meal diet. Levels of .135 and .09% (daily intake of 208 and 139 mg) supplemental chloride were required for maximum egg production and egg weight, respectively. However, a supplemental level of .135% was required to maximize hatchability.
