Production performance of TANUVAS Aseel under different systems of rearing in Kallakuruchi district, Tamil Nadu, India

The present study was conducted to evaluate the production performance and adaptability of TANUVAS Aseel in different rearing systems (Intensive, Semi-intensive and Free range) of Kallakuruchi district in Tamil Nadu, India. As a part of Front line demonstration 2020–2021, 300 numbers of day old straight run TANUVAS Aseel chicks were purchased from Poultry Research Station (TANUVAS), Chennai and distributed to the 10 beneficiaries of Kallakuruchi district. of these, 3 farmers were from Kalvarayan hills practicing free range system, 3 farmers practicing intensive system of management with all standard procedures and 4 farmers were practicing semi-intensive system with partial feeding were included in the study. After distribution at 12^th week, intensive, semi-intensive and extensive system reared birds were scored for live body weight and our study showed live body weight of 1088.85, 802.50 and 533.86 g, respectively. Intensive system had feed consumption and feed conversion ratio of 3752.74 g and 3.45. Free range system of rearing had significantly lower body weight when compared with other two system of rearing. There was no significant difference in livability per cent of Aseel reared under different system with mean livability of 90 per cent. It was concluded that Aseel had higher adaptability to survive under varying system of rearing and it is highly suitable for backyard poultry farming.
