Results showed that the embryo shape of became gradually defined as embryo aged.
On day 6, the head and body of quail were clearly differentiated, the legs became longer and the wings appeared.
At 7 embryo age, the entire embryo of quail was very clear, and the beak has formed.
During 3 to 9 days of age, quail embryos length increased quickly, showing a linearly upward trend.
At 9 day old, quail embryos length reached 2.2 cm.
The regression equation of embryo length to day old was curve regression, giving as following: y=-0.464 0.325x-0.004x2, y: embryo l...
