recent experiment was performed in order to determine effects of dietary l-threonine supplementation levels in japanese quails’ diets on performance, reproductive and internal organs and feathers growth. one hundred and forty four, 1-d old japanese quails, have been selected and randomly distributed between six treatments and four replicates. basal experimental ration was based on wheat, withou...

The study is to evaluate the effect of age and sex on serological indices of Japanese quail (Coturnix coturnix japonica) reared in derived savanna area of Nigeria. A total of 200 quails comprising 100 each of male and female were selected for this study. Fifteen each of the males and females quails were randomly selected at each week of 6, 7, 8, 9, 10 and 11 respectively. Data were obtained on ...

In human bipedal walking, temporal changes in the elevation angle of the thigh, shank and foot segments covary to form a regular loop within a single plane in three-dimensional space. In this study, we quantified the planar covariation of limb elevation angles during bipedal locomotion in common quails to test whether the degree of planarity and the orientation of the covariance plane differ be...

A study was carried out to determine the effect of crude protein level in diets on Serum Biochemical Indexes and Gastrointestinal Micro flora of yellow quails. Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 yellow quails during 50-day-old to 95-day-old in this experiment. The quails were randomly assigned to 4 groups by similar body weight, e...

Male Japanese quails were treated with melatonin alone or melatonin combined with D1 and D2 dopamine receptor blockers. Following the treatment, hypothalamus, pituitary glands and testes were analyzed morphometrically. The results suggest the existence of an interaction between melatonin and dopaminergic system in the brain in the regulation of reproductive processes in immature birds. The char...

three experiments were carried out for isolation of bacteriophage against growth reducing enterococcus faecalis and evaluation of its efficacy to control enterococci colonization in intestine of japanese quails. in experiment one, 60 enterococci spp were isolated from gastrointestinal contents of adult quails, which among them seven isolates were selected based on preliminary tests. in experime...

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...
