Hatching success and chick mortality of the ostrich (Struthio camelus) in a commercial farm in Nepal

Commercial ostrich farming for trading meat and feathers is relatively new in Nepal. This study investigated hatching success and chick mortality rates in the only commercial ostrich farm in Nepal- Ostrich Nepal Pvt. Ltd, Rupandehi, Lumbini Province, Nepal. The number of eggs laid, hatched and their mortality were observed from 2014 to 2020. Results revealed higher embryonic deaths than hatching percentage, however, chick’s mortality rate was comparatively lesser. Breeding population required more nutritional diet to ensure fertile eggs. Hatchability was affected by temperature, humidity and turning of eggs. Microbial contamination and infertility were the major contributors for embryonic death. Intense care is required for the young chicks as they are very vulnerable to heat, rain and infections. Nutrition, and proper temperature and humidity management are major aspects to foster the growth and development as well as to ensure better reproductive ability of ostriches in order to lower mortality and avoid economic loss.
