Role of the caeca in Japanese quail energetics

Canadian Journal of Zoology, 1975
We investigated the caecal contribution to the energy budget of Japanese quail (Coturnix coturnix) through feeding and metabolic studies of intact and caecectomized birds. The feeding trials indicated that, under the conditions described, the caeca contributed 5.7% of the mean daily energy requirements of the quail.

RNase A activity in Japanese quail oocytes

Zygote, 1996
SummaryThe presence of RNase A activity was studiedin vitroin homogenates of quail oocytes and early embryos using [3H]poly(U) as a substrate. The activity was measured by adsorption of the undegraded substrate onto DE-81 filter paper discs and by chromatographic separation on a Sephadex G-50 column.

Are there facial indicators of positive emotions in birds? A first exploration in Japanese quail.

Behavioural Processes, 2018
The positive aspect of emotions, like pleasure, remains overlooked in birds. Our aim was to contribute to the exploration of facial indicators of positive emotions.

Experimental Studies of Chlamydiosis in Japanese Quails

Zentralblatt für Bakteriologie, 1999
Two-week-old Japanese quails were infected intratracheally with six strains of Chlamydia psittaci isolated from calf pneumonia, swine pneumonia, goat abortion, sheep abortion, kid enteritis, and calf conjunctivitis, respectively. The Japanese quails from infected and control groups were closely observed for clinical symptoms.

Systemic Amyloidosis in Laying Japanese Quail

Avian Diseases, 1998
Systemic amyloidosis was seen in laying Japanese quail in a flock of a farm rearing 95,000 birds. The clinical signs included decreased egg production, anorexia, white diarrhea, and subcutaneous abscesses of the head. Histologically, amyloid deposited predominantly in the spleen and liver.

Genetic Resistance to Aflatoxin in Japanese Quail

Science, 1979
Progress was rapid in attempts to develop lines of quail resistant to acute aflatoxicosis induced by oral dosing with aflatoxin. After five generations of selection, 8- and 11-fold differences were present in mortality between two selected lines and their respective control lines.

Screening for Transgenic Japanese Quail Offspring

Cold Spring Harbor Protocols, 2009
INTRODUCTIONAfter mosaic founder breeding pairs of Japanese quail start to produce fertile eggs, the hatchlings must be screened for germ-line transmission to the subsequent G1 generation. This article describes how to isolate hatchling genomic DNA from the chorioallantoic membrane (CAM), which remains inside the egg after hatching.

Taste discrimination in bobwhite and Japanese quail

Animal Behaviour, 1965
Abstract Groups of bobwhite and Japanese quail, at 10 days and at 6 weeks old, were tested in the 4 taste modalities: sweet, sour, salt and bitter. Drinkers of contrasted colours were used for the test solution and for tap water, giving extra visual stimulus to aid optimum discrimination.
