Abstract | Hatching time, hatchability of fertile eggs and embryo mortality under standard egg storage and incubation conditions were analysed in two lines of Japanese quail, HG and LG, that have been divergently selected for shape of the growth curve. The results showed that the genetically determined shape of the growth curve is an important factor influencing hatching time and hatchability. A relatively high growth rate immediately after hatching (typical for the LG vs HG) was associated with a shorter incubation period and higher hatchability of fertile eggs. This was due to lower embryo mortality during early and late incubation periods. |
