the main objective of this study was to elucidate the effect of short- term exposure of japanese quail eggs to acute high incubation temperature on embryonic development and on the ability of post- hatched chicks to cope with subsequent heat stress conditions during the growing period. a total of 998 japanese quail eggs were divided into two groups, the first group (470 eggs) was maintained at ...

Feeding quail chicks diets containing soybeans fermented with two cultures of Aspergilli (A. oryzae N.R.R.L. 451 and A. oryzae N.R.R.L. 506) resulted in significantly superior weight gains (p less than 0.05) through a 4-week growth period and confirmed previous observations made with identical cultures in broiler studies. Subsequent hen-day egg production and egg size were changed little by die...

Mycotoxins are harmful auxiliary metabolites delivered by species of filamentous organisms developing on grains some time recently collect and in capacity. The study was planned to evaluate the protective role lycopene (LYC) against Aflatoxin B1 (AFB1) induces oxidative stress, hepatic toxicity, apoptosis Japanese quail. Sixty quail chicks (three-week-old) were randomly allocated into four grou...

This research was conducted in the field of poultry Department Animal Production Techniques for period 6/9/2011 until 23/11/2011 order to study effect adding alcoholic extract ginger, propolis and cinnamon (cinnamon) reducing cholesterol yolk white quail eggs, which used 280 one-day-old chicks were divided into seven groups with two replicates each group. The homogeneous weights placed 13 kanna...

Lateralization is the ascendency of one side body or brain to control and perform motor perceptual functions. Light exposure during prenatal life can modulate expression visual lateralization (strength direction) in a variety species, including birds. Individual provides cognitive advantages, but function at population level less obvious. Recent studies support hypothesis that intra-specific po...

The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...

It is obvious from several studies that the different neurotransmitters are associated with various metabolic activities of the body directly or indirectly via their effects on hypothalamic/pituitary hormone but regarding the control of reproductive system catecholamines seem to have a central role. In view of above fact the present study was designed to test whether neurotransmitter precursor ...

Cryopreservation of avian ova and embryos is challenging because of the yolky structure of the egg. As an alternative, with the development of effective cryopreservation protocols, ovarian tissue cryopreservation could be used for cryobanking for birds. Pieces of ovarian tissue of week-old Japanese quail (Coturnix japonica) were frozen at 0.5 degrees C/min in a programmable freezer or vitrified...

this study was conducted to investigate the effect of different levels of sesame meal (sm) on performance and carcass characteristics of japanese quail. one hundred sixty day-old japanese quail chick were equally distributed into 16 cage pens and reared form 10 to 42 days of age. the treatments consisted of sm0, sm50, sm100 and sm150. the diet for sm0 treatment had no sm (control), while those ...
