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...

Gallic acid is a phenolic compound found in many plant sources with strong antioxidant activity. In this study, the bioactivity of was investigated Japanese quails induced by oxidative stress. The study performed on four groups 40–day–old male quail (Coturnix japonica). Oxidative stress created for 1 week adding 0.5% hydrogen peroxide. terminated administering 100 mg·kg-1 body weight intraperit...

A total of 240, one-day-old quail chicks (Coturnix coturnix japonica) were used to study the effects of Artichoke leaf meal (ALM) and vitamin E in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. This experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

Eggand meat-type quails were reared in groups of different sizes with a fixed female-to-male ratio of 2 to 1 and an area of 158 cm per bird. The aim was to investigate the influence of group size on quail production and reproductive variables. To this end, 360 quails (180 meat and 180 egg-type quails) were assigned in a completely randomized experimental design to one of three treatments with t...

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...

The objective of this study was to determine the influence housing system on physical, morphological, and mechanical properties Japanese quail (Coturnix coturnix japonica) eggs. A total 240 eggs were collected from quails kept in two different systems: cage aviary (120 each system). Eggs significantly (P<0.05) heavier than (11.85 g vs. 10.93 g), also longer, wider had larger geometric mean diam...

Nutrient composition of the grasshoppers Oxya hyla hyla showed that they are a rich nutrient source containing 687.7 g protein/kg of dry body weight. Their antinutrient values fell within nutritionally acceptable values of the poultry bird Coturnix japonica japonica (Japanese quail). The most required essential amino acids and fatty acids were also present in sufficient amount. For feeding tria...
