Three experiments were conducted to study the Met and protein requirements of Arbor Acres broiler breeder hens. Broken line regression analysis in Experiments 1 and 3 indicated the Met requirement was 335 and 323 mg/d, respectively, with a production of a daily egg content (EC) of 42.3 or 43.0 g. A broken line could not be fitted to the data in Experiment 2. Therefore, this procedure could not be used to calculate a requirement. An average of 7.83 mg Met was required to produce 1 g of EC. Using this value, the requirement for the three experiments would be 344 mg at the level of EC produced in these experiments. The requirement would be higher with either a higher rate of lay or with larger eggs.
