Abstract :

An experiment was conducted at Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy to evaluate and compare the production performance of progenies of Australorp with F, N and P strains of White Leghorn (viz., AW-F, AW-N and AW-P) under deep litter system of reå. The mean age at sexual maturity was significantly (P<0.05) earlier in AW-P (147.40 days) than AW-F (162.60 days), meanwhile for AW-N birds it was comparable to other two groups (153 days). The mean age at 50 per cent production was significantly (P<0.01) earlier in AW-P (165.60 days) and AW-N (169.60 days) birds than AW-F (179.40 days) birds. Egg production up to 40 weeks of age was significantly (P<0.05) higher in AW-N (54.52 per cent) and AW-P (61.74 per cent ) birds than AW-F birds (46.94 per cent). Overall feed conversion ratio per dozen of eggs produced in AW-N (2.13) and AW-P (1.93) was significantly (P<0.05) higher than that of AW-F (2.53) birds. The results revealed that AW-N and AW-P birds can perform better than AW-F under deep litter system upto 40 weeks of age.
