Layer
Layer
Layer poultry farming means raising egg laying poultry birds for the purpose of commercial egg production. Layer chickens are such a special species of hens, which need to be raised from when they are one day old. They start laying eggs commercially from 18-19 weeks of age. India has emerged on the world map as the 3rd largest egg producer (75 billion eggs) and annual growth rate in egg production approximated 6% per year (BAHS 2015). The current strength of layers in India is estimated to be 214 million (livestock census 2012) and the annual percapita availability of eggs has increased from 7 eggs in 1961 to 61 eggs in 2014. However, the present availability is far below the ICMR recommendation of 180 eggs per capita per annum.
CARI DEBENDERA
CARl Debendra is a medium-sized dual-purpose bird, produced by crossing coloured synthetic broiler line as male line and Rhode Island Red as female line. It is the most suitable bird for the Indian consumers due to its attractive bright plumage colour. The bird achieves moderate body weight at eight weeks of age with economic feed conversion ratio. The meat has lower carcass and abdominal fat than broiler meat, which makes it a consumer's delight. CARl Debendra is also a suitable bird for rural poultry because of its better survivability and moderate egg production ability.

CARI PRIYA
Breeders of egg type chicken are primarily concerned with the development of quality layers in terms of high egg production, feed efficiency, livability and low chick cost. CARl Priya, earlier known as ILI-80, is one such commercial white egg layer. CARl Priya was developed by crossing superior male and female strains of White Leghorn.
