A strain of Japanese quail with the polyuria disorder (excessive urination) was developed from founders that regurgitated water spontaneously. A back-cross with a nonpolyuric quail line showed that the polyuric strain was fixed for an autosomal recessive mutation that also induced polydipsia (excessive drinking). Plasma levels and brain mRNA contents for avian Arg vasotocin were little affected...

Objective: The morphological and biochemical impact of a short-period of starvation on Japanese quail was investigated. Materials and Methods: Ten adult male Japanese quail were divided into two groups; control fed and starved. The control-fed group was offered food and water ad libitum and the starved group was subjected to a short-period of food deprivation. After 2.5 days, the serum was obta...

The quail raising in Brazil has increased through the last years and the incubation procedures are important to maintenance and improvement of quail egg production. To obtain a sufficient number of eggs to fill an incubator, eggs are usually accumulated in storage over a period from 1 day up to 3 weeks before incubation. The objective of this research was to verify the effect of egg storage on ...

It is obvious from several studies that the different neurotransmitters are associated with various metabolic activities of the body directly or indirectly via their effects on hypothalamic/pituitary hormone but regarding the control of reproductive system catecholamines seem to have a central role. In view of above fact the present study was designed to test whether neurotransmitter precursor ...

The objective of this study was to determine the impact different ambient temperatures on egg production and hatching parameters in Japanese quail. Sixteen weeks old male female quail were assigned 10 cages as 1 5 females. Quails housed a poultry yard belonging Faculty Agriculture. reared under 16 hours’ light 8 dark photoperiod. During study, water food freely available ad-libitum. Regularly e...

Newcastle disease virus (NDV) was isolated and identified for the first time from a flock of Japanese quail suspected to ND in Iran. Birds of the flock aged variously, and some of them died from the disease. Loss of appetite, weakness and decrease in egg production, diarrhea and nervous symptoms were the main clinical signs in the birds. Hemorrhagic lesions of the intestinal tracts and proventr...

Background: Small intestine and peripheral organs are the main organs for digestion and absorption in the gastrointestinal tract. OBJECTIVES: To investigate effects of different levels of Vitamin E and Selenium on growth performance and small intestine morphometry in Japanese quail. METHODS: A total of 405 mixed sex Japanese quails were randomly allocated into 9 experimental groups by 3×3 facto...

I . Adult male Japanese quail (Coturnix Coturnix Japonica) were overfed at different intensities during varying periods: (I) by gradually increasing the daily amount of food up to twice the control level in a period of 1 1 d and keeping this level constant during the subsequent 12 d period (prolonged overfeeding); ( 2 ) by gradually increasing the daily amount of food up to approximately twice ...

West Nile Virus (WNV) arrived in North America in 1999 and is now endemic. Many families of birds, especially corvids, are highly susceptible to WNV and infection often results in fatality. Avian species susceptible to WNV infection also include endangered species, such as the Greater Sage-Grouse (Centrocercus uropbasianuts) and the Eastern Loggerhead Shrike (Lanius ludovicianus migrans). The v...
