Genetic relationships between water loss and shell deaths in ostrich eggs, assessed as traits of the female
The ostrich industry suffers from a high rate of embryonic mortality during artificial incubation of eggs. Data from 34285 eggs were used to derive 969 female-year records for evaporative water lossExpand
