TLDR
A hatchability rate of 26% is among the best of the various culture conditions examined in the present study and the embryo culture system should facilitate advances in avian biotechnology.Abstract:
The blue-breasted quail (Coturnix chinensis), the smallest species in the order Galliforms, is a candidate model animal for avian developmental engineering because it is precocious and prolific. This species requires 17 days to hatch and 8 to 9 weeks to mature to an adult body weight of about 50 g, whereas the Japanese quail (Coturnix japonica) requires 16 days to hatch and 6 to 8 weeks to mature to an adult body weight of 100 to 150 g. The early embryo is the most challenging embryonic stage in terms of culture and manipulation for avian biotechnology. We have evaluated various conditions for the culture of blue-breasted quail embryos from the blastoderm stage to hatching. A hatchability rate of 26% (10/39) is among the best of the various culture conditions examined in the present study and the embryo culture system should facilitate advances in avian biotechnology.read more

Japanese quail: an efficient animal model for the production of transgenic avians.
TL;DR: Detailed methods for generating transgenic quail using high-titer lentivirus are provided, which offer all of the advantages of the classic avian developmental model system, such as the ability to readily produce quail:chick transplant chimeras.

A Novel Shell-less Culture System for Chick Embryos Using a Plastic Film as Culture Vessels
Yutaka Tahara,Katsuya Obara +1 more
TL;DR: A simple method for culturing chick embryos with high hatchability is established using an artificial vessel and the aeration of pure oxygen to the surviving embryos from day 17 yielded a hatchability of 57.1%.

Parthenogenesis in unfertilized eggs of Coturnix chinensis, the Chinese painted quail, and the effect of egg clutch position on embryonic development
TL;DR: The Chinese painted quail does exhibit parthenogenesis and clutch position influences the rate of naturally occurring parthenogenic development, with a steady decline in the percentage of eggs with embryonic development as position in the clutch increased.

Comparison of learning ability and memory retention in altricial (Bengalese finch, Lonchura striata var. domestica) and precocial (blue-breasted quail, Coturnix chinensis) birds using a color discrimination task.
Aki Ueno,Kaoru Suzuki +1 more
TL;DR: The results suggested that altricial and precocial birds both possess the faculty for learning and retaining discrimination-type tasks, but that Altricial birds perform better than precsocial birds in both faculties.

Developmental stages of the blue-breasted quail (Coturnix chinensis)
TL;DR: A normal developmental series is developed for the blue‐breasted quail based on developmental features as a major criterion of staging in this phase of development was the weight of embryos and the length of third toes.

A series of normal stages in the development of the chick embryo
TL;DR: The preparation of a series of normal stages of the chick embryo does not need justification at a time when chick ernbryos are not only widely used in descriptive and experimental embryology but are proving to be increasingly valuable in medical research, as in work on viruses and cancer.

A series of normal stages in the development of the chick embryo
TL;DR: In this article, a series of normal stages of the chick embryo is described in terms of the length of time of incubation, except for the first three days during which more detailed characteristics such as the number of somites are applied.

A complete culture system for the chick embryo
TL;DR: The fertilized ovum of the chick (Gallus domesticus) is cultured for the total embryonic period by growing it in a series of separate culture systems, the first report of a complete in vitro method for a homoiothermic animal.
