***Pullets and hens of Leghorn-type strains are generally fed ad libitum but are occasionally control-fed to limit body weights. Values shown are typical but will vary with strain differences, season and lighting. Specific breeder guidelines should be consulted for desired schedules of weights and feed consumption.
****Based on diets containing 2,900 ME kcal per kilogram, consumption will vary depending upon the caloric density of the diet, environmental temperature and rate of production.
