* 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/kg, consumption will vary depending
upon the caloric density of the diet, environ- mental temperature and rate
of production.
