India is an agriculture based country

(భారతదేశమువా వసాయఆధారితదేశము).

Ever increasing demand for food needs of the

growing population is not totally met by the agriculture

and it products alone.

Poultry farming is found to be the best alternative

and thus it has become the second best profession

for many people of India.

To day poultry industry is the fastest growing sector

(వేగవెంతెంగాఅభివృది్ధ చెందులతున్న రెంగము) of India’s

agriculture.

The Aseel, a famous Indian breed, was highly prized by

lovers of cock fighting all over the world.
