Abstract

Study on months and seasonal influence on hatching performance of ostrich was carried out at the Post Graduate Research Institute in Animal Sciences, Tamil Nadu Veterinary and Animal Sciences University, Kattupakkam, Kanchipuram district, Tamil Nadu. To assess the hatching performance a total of 1439 ostrich eggs were used in this study. Hatching performance viz., fertility, total hatchability, fertile hatchability and embryonic mortality were assessed. The result showed that month and season had a significant influence on fertility, total hatchability, fertile hatchability and embryonic mortality. Higher per centage of fertility (48.46) and total egg hatchability (16.04) were observed during November month. Season had a highly significant (P≤0.01) influence on fertility performance in ostrich and comparatively highest percentage of fertility were observed during northeast monsoon (33.77) and winter (31.39) season followed by summer (14.55) and southwest monsoon (10.28) season. Similarly, highest total hatchability percentage was observed during northeast monsoon (11.98) and winter (8.39). Comparatively higher percentage of embryonic mortality were observed during south west monsoon (81.94) and winter (72.85) than summer (64.81) and northeast monsoon (62.47). From the above study, it can be concluded that the hatching performances in ostrich relying on season since, better hatching performance observed during northeast monsoon and winter season.

Conclusion

The above study concluded that months and different season showed significant influence on fertility and hatchability performance in ostrich and considered as a seasonal breeder in tropical climate, which is evident from that significantly better fertility and hatchability were observed during northeast monsoon and winter than summer and southeast monsoon seasons.
