Generally highly meat productive birds or poultry breeds are called broiler poultry. But broiler chicken is a special species of poultry, which is a great secret. Only four countries of the world known about this secret and they supply and maintain all the demand of broiler chickens. Broilers are like other common poultry birds. But this broiler is made in a scientific way for producing more meat in a short time. Basically, broilers are only for meat production birds. India has emerged on the world map as the 5 th largest meat producer (2.68 mmt) and annual growth rate in meat production approximated 15% per year . The current strength of broiler in India is estimated to be 282 million (Livestock census 2012) and the annual per capita availability of meat has increased from 0.16 kg in 1961 to 3.04 kg in 2013. However, the present availability is far below the ICMR recommendation of 11 kg per capita per annum.
Two broiler stocks one each with naked and frizzle gene were developed by introgressing these genes from desi fowl to broiler stocks by conventional crossing. These naked neck and frizzle broiler stocks were crossed to develop CARIBRO Tropicana which has both naked neck and frizzle phenotype.

CARIBRO Dhanraja is a commercial cross produced by crossing coloured synthetic male and female lines. This stock is characterized by its bright plumage colour with single comb. It is also less susceptible to adverse environmental conditions. CARI BRO Dhanraja is the most preferred bird among farmers because of its multicoloured plumage and high economic returns.

CARIBRO Mrityunjay is a commercial cross produced through introgression of naked neck gene into coloured and white synthetic broiler lines by repeated backcrossing. Both coloured and white plumage stocks of CARIBRO Mrityunjay are available. The stock is characterized by its adaptability to high ambient temperature, which make it the ideal bird for tropical environment.

Development of suitable high yielding broiler stocks, entirely different from imported commercial broiler stocks available in the market, has been the endeavor of the Institute. Consequently, CARIBRO Vishal, a broiler that excels in growth, feed efficiency, livability, meat quality and also the plumage colour with high performance features in tropical climate has been developed.
