Microbial contamination and other hatching problems causing dead -in shell in ostrich (Struthio Camelus) eggs during artificial incubation

Microbial contamination and other hatching problems causing dead -in shell in ostrich (Struthio Camelus) eggs during artificial incubation [electronic resource] - p.401-411.
Includes bibliographic reference
Complete data of 451 ostrich eggs from commercial incubators and hatcheries in Egypt were collected. Hatchability rate was only 45 (10%). Fertile and infertile eggs were 266 and 185 ( 59% and 41%) respectively. Fertility varied between eggs collected from different farms. Embryonic
mortalities were higher at the start and end of incubation
period (42 days). Most of these mortalities took place at the late stage of incubation (I 0-14 days) and were found related to percentages of water loss which cause severe oedema and later mass deaths.
