Executive Summary: A two-generation dietary test provides a method for determining multigenerational effects of endocrine disrupting chemicals (EDCs), with varied exposures over the stages in the life cycle. The Japanese quail has been developed as a model for precocial avian species; however, northern bobwhite quail have been the standard for toxicological testing. Our purpose was to compare r...

Maternal behavior has a significant individual variability, as mothers take care differently to their young based on their own breeding experience or age. In this parent-youth system, we investigated whether the young played a role as modulator of maternal behavior. For this, we evaluated how adoptive quail (unstressed) raised chicks coming from stressed female (PS) or not (NPS) thank a social ...

Aim: The present study was designed to evaluate the safety of seabuckthorn (Hippophae rhamnoides L. Elaeagnaceae) leaves added in the diet of Japanese quail. Materials and Methods: A total of ninety quail chicks were randomly divided into 2 groups and fed a standard quail chick mash added with or without 2% SBT leaf powder (Group SX), and a standard quail chick mash (Group CX, control) for 21 d...

Information presented redundantly and in temporal synchrony across sensory modalities (intersensory redundancy) selectively recruits attention and facilitates perceptual learning in human infants. This comparative study examined whether intersensory redundancy also facilitates perceptual learning prenatally. The authors assessed quail (Colinus virginianus) embryos' ability to learn a maternal c...

Populations of red imported fire ants (RIFA; Solenopsis invtcta) have spread rapidly throughout 'the southeastern United States. RIF A, directly or indirectly, negatively affect many wildlife species, _ and northern bobwhite (Col'inus virginianus) appear to be particularly susceptible. We examined the effect of exposure to different numbers of RIF A for 15 and 60 seconds on body mass and surviv...

Aim: The present study was designed to evaluate the toxic interaction of fumonisin B and ochratoxin A, alone and in 1 combination for pathology of the kidneys in day old Japanese quail. Materials and Methods: Day old Japanese quail chicks were divided into 4 groups and fed with basal quail chick mash containing fumonisin B @ 200 ppm (Group FX), Ochratoxin A @ 2 ppm (Group OX), and fumonisin B @...

We examined whether low ambient temperatures influence foraging behavior of precocial Japanese quail chicks and alter the balance between investment in growth and thermogenic function. To test this, one group of chicks was exposed to 7 degrees C and one group to 24 degrees C during foraging throughout the developmental stage. Chicks adapted well to the temperatures through a high flexibility in...
