Production Performances of Japanese Quail Parent Stock under Open Housing System

EFFECT OF HOUSING CONDITIONS ON PERFORMANCE OF JAPANESE QUAIL (Coturnix coturnix japonica) UNDER COLD STRESS IN WINTER

The effect of different housing conditions on body weight, weight gain, feed intake, water consumption, egg production, rectal temperature, hematocrit value and mortality rate were studied in Japanese quail. Three experimental groups: winter conditions (control), long day-light (lighted) and hot climate (heated) were used. A total of 195 quail chicks (65/group, 40 females and 25 males) were use...

Histomorphometric study of brachiocephalic artery of Japanese quail

Brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. The aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the Japanese quail. The different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old Japanese quail; (n = 6) and both sexes. Luminal diameter, th...

Development and performances of a Japanese quail line homozygous for the diabetes insipidus (di) mutation.

A strain of Japanese quail with the polyuria disorder (excessive urination) was developed from founders that regurgitated water spontaneously. A back-cross with a nonpolyuric quail line showed that the polyuric strain was fixed for an autosomal recessive mutation that also induced polydipsia (excessive drinking). Plasma levels and brain mRNA contents for avian Arg vasotocin were little affected...

The Use of Sesame Meal in Diets of Japanese Quail

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 ...
