ABSTRACT

Ostriches are being reared in India from 2000 onwards. The data on reproductive performance recorded over a period of seven years (2002 – 2008) were analysed. Ostriches revealed sexual dimorphism at an age of around 270 days and the mean age of sexual maturity observed was 787.8 ± 29.9 days. The average annual egg production over seven years of study was 18.6 ± 2.9, 35.1 ± 4.9, 34.4 ± 5.8, 28.7 ± 4.6, 32.5 ± 5.0, 26 ± 5.4 and 25.1 ± 3.4 per female and no significant variations were observed. The mean egg weight during this period was 1480.02 ± 56.35 g and the effect of year of production was significant (P
