abstract
A total of 400 day old chicks comprising of two groups (T1- Nandanam broiler-2 and T2 - Nanadanam broiler-3 chickens and) with four replicates of 50 chicks each and reared up to 8^th week of age under intensive system. Production performance of birds was assessed based on biweekly bodyweight, feed conversion ratio and livability. The results revealed that there were no significant (P>0.05) differences observed in mean body weight (g) at initial growth periods, i.e., from 0-2 weeks of age between. Significantly higher (P£0.01) mean body weight (g) was observed in Nanadanam broiler-3 chickens from 4 to 8 weeks of age than Nandanam broiler-2 birds. Significantly better (P£0.01) cumulative feed conversion ratio was recorded in Nanadanam broiler-3 than Nandanam broiler-2 and per cent livability did not differ. It is concluded that Nanadanam broiler-3 chickens had significantly higher production performance than Nandanam broiler-2 birds under intensive system of management.
