Morphological and Hematological Responses to Hypoxia During Development in the Japanese quail, Coturnix coturnix
Hypoxic responses in quail development differ depending upon stage, duration and level of oxygen partial pressure of embryo. Incubation was switched to/from 110mmHg partial pressure (hypoxia), to/from 150mmHg (normoxia) during different stages in development, and control was incubated in normoxia …

Adrenal response to chronic and acute water stress in Japanese quail, Coturnix coturnix japonica
Adrenal corticosterone and aldosterone content, body weight changes and serum osmolality were examined during water restriction and water deprivation. Progressive water deprivation resulted in increased serum osmolality and decreased body weight; adrenal aldosterone content did not change. Adrenal …

The role of body composition in the onset of lay of Japanese quail (Coturnix coturnix japonica)
This study was designed to examine the influence of dietary protein and restricted feeding on body composition of Japanese quail at the onset of lay. The first experiment utilized five isocaloric diets containing either 26%, 24%, 20%, 16%, or 14% crude protein. Each diet was fed to three groups of …

Chromosomal localization of a proinsulin transgene inserted with a transposon-based vector into Japanese quail, Coturnix coturnix
The overall goals of this research were to develop a reproducible method of detecting stable DNA insertion into Japanese quail and provide a method for gene location on avian chromosomes. This research resulted in the development of a different method of obtaining chromosome spreads in Japanese …

Immunomodulation by dietary lipids: soybean oil, menhaden fish oil, chicken fat, and hydrogenated soybean oil in Japanese quail (Coturnix coturnix japonica) and Bobwhite quail (Colinus virginianus)
Soybean oil (SBO), menhaden fish oil (FO), chicken fat (CF) or hydrogenated soybean oil (HSBO) were incorporated at 5% of the total diet to study changes in the immunological status of both Japanese quail (JAP) and Bobwhite quail (BOB). The SBO diet, in which 66% of the total fatty acids were …

Effects of dietary fats on reproductive performance , egg quality, fatty acid composition of tissuse and Yolk and prostaglandin levels of embryonic tissues in Japanese Quail (Coturnix coturnix japonica)
… levels in embryonic tissues in Japanese quail (Coturnix, coturnix japonica) were evaluated. The addition of 5.0% chicken fat (CHX), hydrogenated soybean oil (HSBO), menhaden fish oil (MENH) or soybean oil (SBO) to the maternal and paternal diet altered tissue and yolk composition of the hens and …

The effects of induced hypothyroidism on the glucocorticoid stress response in Japanese quail (Coturnix japonica)
Many aspects of biological function are affected by hormones, from physiology to behavior, and the synthesis and release of hormones in vertebrates are regulated by the endocrine axes of control. A growing body of research shows that the mechanisms underlying the endocrine axes of control are …

The Effects of Dietary Lipids on Bone Chemical, Mechanical and Histological Properties in Japanese Quail (Coturnix C. Japonica)
Japanese quail were used as animal models in four experiments to evaluate the effects of supplementing diets with different lipids on bone chemical, mechanical, and histological properties. In Exp. 1, laying hens were fed a basal diet containing either 5% soybean oil (SBO), hydrogenated soybean oil …

Contaminants at a Shooting Range: Toxicological and Nutritional Significance to Birds and Mammals
… wildlife, I conducted controlled experiments on Coturnix quail exposed to clay targets in the lab, and collected wild birds and mammals exposed to lead pellets at a shooting range. The first Coturnix study determined whether quail voluntarily consumed target fragments or limestone fragments. In …

Chromosomal inversions and common quail diversification in Macaronesian archipelagos and the mainland
… within the highly mobile common quail (Coturnix coturnix), and the impact these structural changes have on the population fragmentation, species diversification and on its genome evolution. Since the assessment of the gene flow between populations is a key element to understand how …

Chromosomal inversions as a mechanism for sympatric differentiation in common quails
… remain poorly understood. In the common quail Coturnix coturnix, a large inversion on chromosome 1 spans about 12% of the genome and defines three karyotypes (AA, AB, BB) that differ in morphology and migratory behaviour while still coexisting and interbreeding in parts of the western …

Blood characteristics as predictors of reproductive success in quail species exposed to DDT
… and reproductive success in Japanese quail (Coturnix coturnix japonica) or northern bobwhites (Colinus virginianus). The utility of vitellogenin as a biomarker in northern bobwhites was investigated. Female northern bobwhites were dosed with 0, 1, 10, or 100 μg DDT/g body weight via corn oil …

Fat deposition in relation to sexual maturation of Japanese quail
… sexual maturity were studied in Japanese quail (Coturnix coturnix japonica). In an initial experiment, body composition and sexual maturity were examined in response to photoperiodic and hormonal manipulations. Attempts were made to modify body composition, and thereby age at sexual maturity, by …
