Pathological studies of Japanese quail, which were inoculated intraperitoneally with JM strain of Marek's disease herpesvirus (MDHV) at one day of age or infected by contact with inoculated-quails, were described. A group of quails accidentally infected with Marek's disease (MD) and other un infected normal quails were also included in the present experiments. The quails were examined for vario...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
Retinal ganglion cell loss was investigated in the retinae of albino quails before and after the development of glaucoma. The isodensity maps of ganglion cells, the total number of ganglion cells, and the histograms of the cell size in the central region of the retina were similar between albino quails without glaucoma and pigmented quails. However, ganglion cells in the intermediate and periph...
Efficient conversion of food into body mass has been associated with altered gene expression of some proteins of the electron transport chain. We evaluated the effect of age on mRNA expression of uncoupling protein, adenine nucleotide translocase and cytochrome c oxidase complex III in quails. One-day-old broiler quails were sacrificed after 7, 14, 21, or 28 days. Six quails of each age we...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
This study was aimed at determining the effects of dietary zeolite (clinoptilolite) supplementation on fattening performance, slaughter characteristics, and some blood visceral organ parameters in Japanese quails. For this purpose, 140 (4x35) four-day-old quail chicks (Coturnix coturnix japonica) were randomly assigned to 4 groups with replicates (9+9+9+8), continued for a period 31 days. The f...

within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
1. Head injuries caused by aggressive pecking are an important welfare problem in quail farming. The aim of experiments one to three was to reduce the rate of aggressive pecking in breeder groups. 2. The quails were housed in pens containing litter, nest boxes and a dustbathing box. The experimental groups consisted of 2/14, 3/14, 5/15 or 5/35 (males/hens) quails which were introduced into the ...
In order to perform a histomorphometric study of blood cells in male adult ostrich, blood samples were obtained from jugular vein of 10 clinically healthy male adult ostriches (2 - 3 years old). The slides were stained with the Giemsa methods and the smears were evaluated for cellular morphology, with cellular size being determined by micrometry. The findings of this study revealed that the sha...
