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...

Present preliminary scientific trial was designed to investigate of microwave effects on Japanese quails as an animal model. Thirty six three days-old quail chicks were randomly divided into 3 experimental groups and received: A) un-treated tap water, B) tap water boiled by electrical heater and then cooled and C) tap water treated by microwave oven and then cooled. The whole experimental perio...

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...

Growth hormone gene plays a critical role in regulating growth and metabolism which leads to potential correlations between the polymorphisms of this gene and economic trait. A 776 bp fragment within the intron 1 region of the growth hormone gene from 346 individuals of an F2 population of Japanese quail was amplified. The polymerase chain reaction (PCR) product was digested using MspI restrict...

This study was performed to evaluate the efficacy of two levels of dietary oregano essential oil (OEO) on growth performances, biochemical, hematological parameters, and intestinal histomorphology in Japanese quail. A total number of 99 quail chicks were divided into three groups (33 quails per group): Control, OEO 150 mg kg-1, and OEO 300 mg kg-1 treated groups for 42 day...
