Endocrine disruption caused by oral administration of atrazine in European quail (Coturnix coturnix coturnix)

open access: yesComparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2012
The widely used herbicide atrazine (ATZ) has been reported to exhibit reproductive toxicity in rats, fish and amphibians, with an avian LD(50) of 5000 mg/kg. In the present work, ATZ was administered as a single oral dose of 25 or 100 mg/kg to female European quail (Coturnix coturnix coturnix) at days 0, 5 and 10 of the experiment, being the animals ...

Non-destructive Multibiomarker Approach in European Quail (Coturnix coturnix coturnix) Exposed to the Herbicide Atrazine

open access: yesArchives of Environmental Contamination and Toxicology, 2013
The effect of orally administered atrazine (25 or 100 mg/kg on days 0, 5, and 10 of the experiment) was studied in European quail (Coturnix coturnix coturnix) on four non-destructive biomarkers: fecal porphyrins, blood glutathione-S-transferase, glutathione reductase, reduced glutathione, and malondialdehyde (MDA).

Postcopulatory sexual selection favors fertilization success of restocking hybrid quails over native Common quails (Coturnix coturnix) [PDF]

open access: yesJournal of Ornithology, 2015
Postcopulatory sexual selection plays an important role in the reproductive success of males in many species. Differences in fertilization success could affect rates of admixture and genetic introgression between divergent lineages. We investigated sperm

Elevating Testosterone and Androstenedione Produces Temporary Sex-Dependent Variation in Japanese Quail (Coturnix japonica) Embryonic Development. [PDF]

open access: yesJ Exp Zool A Ecol Integr Physiol
ABSTRACT Vertebrate growth rates may respond to maternally supplied steroids, yet injections of individual hormones into avian eggs of different species have produced inconsistent results. This might be because diverse steroids' concentrations are naturally correlated in yolks, injections are not elevating hormones at critical times in development, or ...

The potency of Lactobacillus acidophillus and L. lactis probiotics and Guazuma ulmifolia Lam. extract as feed additives with different application times to improve nutrient intake and feed efficiency in Coturnix coturnix japonica females

open access: yesJournal of Animal and Feed Sciences, 2022
. Research on the combination of Lactobacillus acidophillus and L. lactis probiotics and Guazuma ulmifolia Lam. to find an alternative to antibiotic growth promoters has never been conducted, thus the present study aimed to evaluate their effect on ...

Desenvolvimento embrionário e eclodibilidade de ovos de codornas armazenados por diferentes períodos e incubados em umidades e temperaturas distintas Embrionary development and hatchability of quail eggs stored for different periods and incubated at different humidity and temperatures levels

open access: yesRevista Brasileira de Zootecnia, 2006
Objetivou-se avaliar parâmetros relativos à incubação de ovos férteis de codornas japonesas. Os ovos foram armazenados por três períodos (0, 72 e 144 horas) e incubados em duas umidades relativas (55 e 65%) e duas temperaturas (36,5 e 37,5°C ...

Stress induced polarization of immune-neuroendocrine phenotypes in Gallus gallus [PDF]

open access: yes, 2017
Immune-neuroendocrine phenotypes (INPs) stand for population subgroups differing in immune-neuroendocrine interactions. While mammalian INPs have been characterized thoroughly in rats and humans, avian INPs were only recently described in Coturnix ...
