Developmental biology research has used various avian species as model organisms for studying morphogenesis, with the chick embryo being used by the majority of groups. The focus on the chick embryo led Hamburger and Hamilton to develop their definitive staging series nearly 60 years ago and this series is still the mainstay of all laboratories working with avian embryos. The focus on the chick...

Specific temporal phase relation of neural oscillations appears to be the regulator of gonadal development in many seasonally breeding species. To find out the specific phase angle of two neural oscillations that triggers gonado-inhibitory or gonado-stimulatory response, and to test the internal coincidence model, sexually immature male Japanese quail were administered with the serotonin precur...

The interactions between the effects of three plumage color mutations taken two-by-two (sex-linked recessive roux, autosomal recessive lavender, and autosomal dominant beige) were studied in Japanese quail by producing a total of 121 F(1) and 1118 F(2) quail from the three pure stocks. Three new plumage colors were obtained in F(2) quail: roux-diluted beige, cream, and lavender-diluted beige. T...

the present research was conducted to estimate the dietary lysine (lys) requirements of growing quails as based on performance and carcass constituents parameters at 3 to 24 d of age. the experiment was carried out in a complete randomized design arrangement the 6 dietary lys levels; 1, 1.15, 1.30 (nrc 1994), 1.45, 1.60, and 1.75 %, from 3 to 24 d of age. a dose-response diet mainly based on co...
