dc.description.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 < 0.01). The egg weight progressively increased from 1161.1 ± 30.90 g to 1663.23 ± 37.02 g. Egg production was observed during all months of the year with maximum number of eggs recorded in the month of January 384 (13.3%) followed by 326 (11.3%) in December and the lowest of 163 eggs (5.6%) during May. The total number of eggs produced during the seven year period was 2886 at the rate of 412 eggs per year at a laying rate of 29.2 ± 4.6 eggs per hen. The result of this study reveals that the reproductive performances of ostriches are quite comparable and the birds had adapted to the Indian conditions. | en_US |
