Gastric hypertrophy associated with cryptosporidiosis in a snake

Abstract

this abnormal position (malposition II) is associated with poor hatchability and usually is the result of incubating eggs in the horizontal or air cell-down position or with inadequate egg turning.11-15Gener ally, ostrich eggs are symmetrical; therefore, egg shape usually is not a useful criterion for identifying the end of the egg with the air cell (ie, the large end of the egg).In the present study, the high incidence of dead embryos in malposition II and the generally poor hatchability of artificially incubated ostrich eggs indicate that further investigation of the effects that egg turning and egg position have on hatchability and chick survival is warranted.
