Previous investigations reported that some traits of parental relationships, including pair-bond duration or mate behavioural compatibility, influence subsequent offspring fitness by acting on their behaviour and growth and thus their early survival. We hypothesized that the development of a pair bond between sexual partners would have a prenatal influence. This study investigated the impact of...

The guideline no. 206 for testing of chemicals of the Organization for Economic Cooperation and Development (OECD) comprising an avian reproduction test using the Japanese quail (Coturnix coturnix japonica; Termminck and Schlegel 1849) as pair-hold test organisms has been applied in a version that reduced the treatment period to 6 weeks without any pretreatment. In the present study bis(tri-n-b...

The genetic diversity of domestic quail and two wild quail species, Japanese (Coturnix coturnix)and Common quail (Coturnix japonica), found in China was studied using microsatellite DNA markers. According to a comparison of the corresponding genetic indices in the three quail populations, such as Polymorphism Information Content (PIC), Mean Heterozygosity ( H ) and Fixation Index, wild Common q...

This study was performed to evaluate the efficacy of two levels of dietary oregano essential oil (OEO) on growth performances, biochemical, hematological parameters, and intestinal histomorphology in Japanese quail. A total number of 99 quail chicks were divided into three groups (33 quails per group): Control, OEO 150 mg kg-1, and OEO 300 mg kg-1 treated groups for 42 day...

this experiment was carried out to determine the effect of different levels of sumac powder (rhus coriaria l.) in the ration with and without probioenzyme on the performance and parameters of blood cholesterol and triglycerides of japanese quail, from the age of 8 to 42 days, based on a completely randomized design, containing 8 treatment, 3 repetion, and 5 chicks of quail with both sexes in ea...

The aim of the study was to investigate effect feeding Japanese quail chicks with diets containing different levels Moringa oleifera leaf and canola seed powder on growth performance, carcass yield, blood plasma constituents, egg production. trial lasted for a total 7 weeks, 5 weeks fattening two laying. first group control group, while second supplemented leaves (4g/kg diet), third fourth mix ...

BACKGROUND: Exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. OBJECTIVES: In the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. METHODS: In a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. All birds received one of four experimen...

Present preliminary scientific trial was designed to investigate of microwave effects on Japanese quails as an animal model. Thirty six three days-old quail chicks were randomly divided into 3 experimental groups and received: A) un-treated tap water, B) tap water boiled by electrical heater and then cooled and C) tap water treated by microwave oven and then cooled. The whole experimental perio...
