TL;DR: Respiratory activity and total lipid content were measured on whole blood samples obtained from 4-week-old sexually immature Japanese quail of both sexes and the addition of glucose to the blood samples did not alter the respiratory activity.
Abstract: 1. 1. Respiratory activity and total lipid content were measured on whole blood samples obtained from 4-week-old sexually immature Japanese quail of both sexes. 2. 2. For the combined group of males and females, the mean oxygen consumption of the blood of control quail was 164 μl/ml per hr, stilboestrol-treated birds 118 and testosterone-treated birds 174. 3. 3. Blood lipid levels were 1·89 g/100 ml in control, 1·42 in stilboestrol-treated and 1·92 in testosterone-treated quail. 4. 4. The addition of glucose to the blood samples did not alter the respiratory activity.

TL;DR: The high heritabilities for live weight (except sire-daughter regression) and for abdominal fat in Coturnix quail indicate that a selection method could be used to reduce fat and increase live weight.

TL;DR: Under intensive production system and similar feeding and management conditions, the CQ develops better nutritional qualities than JQ, and the comparison of wild and farmed species within CQ reveals more similarities than differences.

TL;DR: A low-cost method using common laboratory equipment based on Allele-Specific Multiplex-Polymerase Chain Reaction was developed to undertake reliable molecular identification of the sex of Coturnix japonica directly at hatching.
Abstract: 1. The quail is a potentially important avian model for molecular studies; a major drawback is the inability to sex visually before 3 weeks of age. Molecular sexing is therefore an absolute requirement when animals are sampled before that age. 2. A low-cost method using common laboratory equipment based on Allele-Specific Multiplex-Polymerase Chain Reaction was developed to undertake reliable molecular identification of the sex of Coturnix japonica directly at hatching. 3. This simple method works with down feathers collected from behind the neck of the newly hatched quail and includes internal controls during the PCR to limit risks of error. Males and females can be discriminated on the basis of the presence of one or two amplicons, respectively.

TL;DR: The major routes of excretion of 99mTc in the Japanese quail are by way of the growing oocytes (if present), the liver and the kidneys, where the less mature the oocyte the greater was the nuclide concentration.
