The avian embryo has been a classical model to study early development because the embryo is easily accessible for manipulation of embryonic cells and structures. The usefulness of the chicken embryo increased with the development of quail-chick transplantation techniques (1,2). The ability to transplant Japanese quail cells into a chicken embryo provides a method to trace the developmental fat...

We previously showed that 3-methyl-4-nitrophenol (4-nitro-m-cresol, PNMC), a component of diesel exhaust particles and a degradation product of the insecticide fenitrothion, has reproductive toxicity in adult male and immature female Japanese quail (Coturnix japonica). Here we investigated effects of PNMC on the reproductive toxicity of mature female Japanese quail. The experiment consists of 3...

An experiment was conducted to study the effects of soybean, linseed and sunflower oil (various sources of fatty acids) with and without L-carnitine supplements (0 and 50 mg kg-1) on performance, blood biochemical parameters and carcass traits of Japanese quail. One hundred and ninety-two of 7-day old female Japanese quail were randomly assigned to 6 dietary treatments with 4 replicates and fed...

background: in the current iranian poultry industry, antibiotics are the most frequently used additive in poultry feeds to increase productivity. the negative effects on human health, resulting from the consumption of chicken whose feeds contain antibiotics, makes finding an appropriate alternative of great importance. as a result of their nature, herbal extracts could be specifically considere...

According to various reports of beneficial effects of medicinal plants on the performance of broiler chickens and less extensively studies in laying poultries, this study was conducted to find an appropriate and harmless feed additive to enhance the quality and quantity of poultry eggs. The effect of three herbal extracts on quantity and quality of eggs, blood parameters, hatchability, intestin...

The goal of this experiment was to investigating of effects of different levels of nano chromium (N-Cr) in diet on egg quality and blood chromium content of japanese quail. Two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. Experimental treatments include: 1) control national research council (NRC,...
