Why are Indian poultry breeds cross-bred with exotic breeds to improve productivity?
Developing poultry with high yield and local adaptability.
Indian (desi) poultry breeds such as Aseel are hardy, disease-resistant and well adapted to local climate, but their egg and meat yield is low.
Exotic breeds such as White Leghorn give high yields but are less suited to Indian conditions.
Cross-breeding the two combines the desirable traits of both — high productivity from the exotic parent and adaptability, low maintenance and disease resistance from the indigenous parent.
It does not create a new species, does not make birds genetically identical, and is not aimed only at reducing feed needs.
Hence, Developing poultry with high yield and local adaptability.
