Broiler breeder farms raise parent stock which produce fertilized eggs. A broiler hatching egg is never sold at stores and is not meant for human consumption. [9] The males and females are separate genetic lines or breeds, so that each line can be selected for optimal traits for productivity in either females or males, rather than a single line in which a compromise is reached between female ...
A dual-purpose chicken is a type of chicken that may be used in the production of both eggs and meat. [42] In the past, many chicken breeds were selected for both functions. However, since the advent of laying and meat hybrids, industrial chicken breeding has made a sharp distinction between chickens with either function, [ 43 ] so that certain ...
For hens used in egg production in the US, as of 2011 the FCR was about 2, with each hen laying about 330 eggs per year. [25] When slaughtered, the world average layer flock as of 2013 yields a carcass FCR of 4.2, still much better than the average backyard chicken flock (FCR 9.2 for eggs, 14.6 for carcass). [26]
To calculate poultry feed, it is important to determine the nutritional requirements of the flock based on their age, breed, and purpose. Using suitable feed ingredients, the proportions can be calculated with the help of a balanced formula or tools like the online layer chicken feed calculator. Finally, the feed is mixed thoroughly and ...
Originally, the primary value in poultry keeping was eggs, and meat was considered a byproduct of egg production. [2] A United States Department of the Interior census in 1840 found American farmers had a total combined poultry flock valued at approximately $12 million ($366 million in today's dollars). [3]

Mass production of chicken meat is a global industry and at that time, only two or three breeding companies supplied around 90% of the world's breeder-broilers. The total number of meat chickens produced in the world was nearly 47 billion in 2004; of these, approximately 19% were produced in the US, 15% in China, 13% in the EU25 and 11% in Brazil.
Kuroilers, a dual-purpose breed producing meat and eggs, can live on a diet of kitchen and agricultural waste, and produce around 150 eggs per year whereas native Indian hens lay only 40 per year. The meat yield per bird of Kuroilers is also greater; males weigh approximately 3.5 kg (7.7 lb) and females about 2.5 kg (5.5 lb) whereas the native ...
