Breeds of Chicken
Chickens are grown for their egg and meat. Likewise they are classified as egg-type chicken and meat-types chickens. Egg type chickens are composed of stock that has been developed for egg production and are maintained for the principal purpose of producing chicks for the ultimate production of eggs for human consumption. Breeds of meat type chickens primarily include broilers, fryers, roasters, and other meat type chickens. Here broilers and other chickens are raised for their meat. Broilers are genetically selected for fast growth and raised for meat rather than eggs e.g. White Synthetic Male line (WSML), white synthetic dam line (SDL), coloured synthetic male line (CSML), coloured synthetic female line (CSFL), introgression of frizzle gene etc.
