This experiment was undertaken to assess the influence of thyme (Thymus vulgaris) and turmeric (Curcuma longa) essential oils on hematobiochemical parameters Japanese quails. One hundred eighty, 6-day old quail chicks were subjected five weeks trial. Quail distributed at random into dietary treatment groups each with three replicates 12 quails per treatment. Quails T0 group fed diet without (Ba...

It has generally been accepted that Aerobacter but not Escherichia spp. utilize uric acid as a primary source of nitrogen (S. A. Koser, J. Infect. Diseases 23:377, 1918; C. C. Chen and L. F. Rettger, J. Bacteriol. 5:253, 1920; N. B. Mitchell and M. Levine, J. Bacteriol. 36:587, 1938). Yet, P. J. Armstrong, Jr., and R. F. Wiseman (Bacteriol. Proc., p. 159, 1962) reported that in rats the degrada...

Parthenogenesis, embryonic development of an unfertilized egg, was studied for many years in turkeys. In fact, as many as 49% of unfertilized Beltsville Small White turkey eggs develop embryos. However, no research exists on parthenogenesis in quail. The Chinese painted quail is a close relative of the more common Japanese quail and, unlike turkeys or chickens, the small Chinese painted quail r...

The epidemiology of inclusion body hepatitis (IBH) was studied in poultry in northern India, from April 1990 to March 1994, to evaluate the various factors responsible for causing and determining the severity of the disease. Broiler chicks and Japanese quail (Coturnix coturnix japonica) were the species examined. The factor observed to be most commonly associated with IBH was the presence of af...

The aim of this study is to determine the hatching characteristics, growth performance and slaughter-carcass traits Japanese quails obtained from quail eggs divided into four classes (G1: less than 8 g, G2: between 8-10 G3: 10-12 G4: heavier 12 g) according egg size. animal material consisted chicks (60 birds were used in each group) a total 525 simultaneously parent flock (random mated, not pr...

Many precocial birds show a robust preference for the maternal call of their own species before and after hatching. This differential responsiveness to species-specific auditory stimuli by embryos and neonates has been the subject of study for more than four decades, but much remains unknown about the dynamics of this ability. Gottlieb [Gottlieb [1971]. Development of species identification in ...

Heat stress is one of the most detrimental confrontations in tropical and subtropical regions of the world, causing considerable economic losses in poultry production. Propolis, a resinous product of worker honeybees, possesses several biological activities that could be used to alleviate the deleterious effects of high environmental temperature on poultry production. The current study was aime...

the present research was conducted to estimate the dietary lysine (lys) requirement of growing female quail base on performance and carcass constitutes at 24 to 42 d of age. a dose-response diet mainly based on corn, corn gluten and soybean meal was used. lys content was minimized in dose-response diet (10 g/kg) while assuring the minimum levels of all other essential amino acids in a manner th...

Individual phenotypic characteristics of many species are influenced by non-genetic maternal effects. Female birds can influence the development of their offspring before birth via the yolk steroid content of their eggs. We investigated this prenatal maternal effect by analysing the influence of laying females' social environment on their eggs' hormonal content and on their offspring's developm...
