To evaluatethe effects of supplementing diets of growing Japanese quails (n=450; 7 days old) with chromium (Cr) yeast and / or mannan oligosaccharides (MOS) on productive performance, carcass traits and the immune system are reported. Diets were a basal diet (control) or the basal diet supplemented with 600 mg Cr-yeast/kg (Cr 1), 1200 mg Cr-yeast/kg (Cr 2), 1.0 g MOS/kg, Cr 1 + MOS or Cr 2 + MO...

The aim of this study was to investigate protein requirements for the maintenance and growth of blue-breasted quail (Excalfactoria chinensis) from 7 to 21 days of age. A total of 180 quails, 7 days old, were randomly assigned to 36 cages and for 2 weeks were fed diets with a metabolisable energy concentration of 12.13 MJ/kg and a dietary CP concentration of 125, 150, 175, 200, 225 or 250 g/kg. ...

The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.3, 6.9, 48.9, 2.1, 32.4, 83.8% and 23.6 MJ kg, respectively. The average Ca,...

The effect of genetically modified (GM) feed components comprising soya bean meal and maize on the performance indices (reproduction, survival rate, growth, egg production, relative weight of chosen internal organs, and basic chemical composition of breast muscle and egg yolk) of Japanese quails was investigated during a 10-generation trial. A total number of 8,438 healthy quail chicks were use...

Dimitrov, D. S., 2014. the lachrymal gland in manchurian and Pharaoh Japanese quails – A histometrical investigation. Bulg. J. Agric. Sci., 20: 1498-1501 the study was carried out on 40 sexually mature and clinically healthy Japanese quails (20 females and 20 males) from the stock hybrids manchurian Golden and Pharaoh. After weighing and determination of metric parameters, 80 lachrymal glands w...

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...

In 2004, 3 and 4 strains of avian influenza virus (subtype H5N1) were isolated from waterfowl and chickens, respectively, in central People's Republic of China. Viral replication and pathogenicity were evaluated in chickens, quails, pigeons, and mice. We analyzed the sequences of the hemagglutinin and neuraminidase genes of the isolates and found broad diversity among them.

An experiment was conducted to study the effect of metabolizable energy (ME) and protein of Japanese quails diets on offspring performance and antibody production against sheep red blood cell (SRBC). A total of 432 Japanese quails (13 week-old) were divided into nine treatments. Each treatment comprised four replicates of twelve birds (9 female and 3 male). Nine diets including three levels of ...
