Relative potencies of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 2,3,4,7,8-pentachlorodibenzofuran (PeCDF), and 2,3,7,8-tetrachlorodibenzofuran (TCDF) were determined in vitro in primary hepatocyte cultures of chicken (Gallus gallus), ring-necked pheasant (Phasianus colchicus), and Japanese quail (Coturnix japonica) embryos. Concentration-dependent effects on ethoxyresorufin O-deethylase (EROD...

All nutrients including proteins, lipids, vitamins, minerals and growth factors required by the developing embryo, as well as a number of defense factors, can be found in avian eggs. Eggs are also a source of other substances with biological functions and activities inter alia immune proteins and enzymes. Although chicken egg consumption is currently at the highest level, eggs from other specie...

Escherichia coli isolates were cultured from diseased Japanese quail and their environment. Of 31 E. coli isolates, 11 were cultured from heart blood of dead Japanese quail and 20 were from dead-in-shell embryos, fluff samples, and footbath and drinking water samples. All E. coli isolates were moderately positive on the Congo red binder test and 14 out of 31 isolates produced hemolysis on sheep...

Aim: The present study was designed to evaluate the safety of seabuckthorn (Hippophae rhamnoides L. Elaeagnaceae) leaves added in the diet of Japanese quail. Materials and Methods: A total of ninety quail chicks were randomly divided into 2 groups and fed a standard quail chick mash added with or without 2% SBT leaf powder (Group SX), and a standard quail chick mash (Group CX, control) for 21 d...

Two hundred and forty Japanese quail aged 125 days were randomly allocated to five treatment groups based on laying (%) quail’s weight (90.71 ± 1.8% egg/day × 100 178.05 9.38 g, respectively), each of which included six replicates eight quails. The diets formulated corn, soybean meal, industrial amino acids. An optimal diet achieves 100% acids required by the requirements, except for threonine....

The current study was conducted to identify the quantitative trait locus (QTL) for the body weight at age 1, 7, 14, 21 and 28 days and daily gain at age 0-1, 1-2, 2-3 and 3-4 weeks, slighter carcass weight and tonic immobility in Japanese quail. Two divergently lines of wild and white Japanese quail which maintained in the Animal Science Research Center of the Shahid Bahonar University of Kerma...

Myoglobin has an important physiological role in vertebrates, and as the primary sarcoplasmic pigment in meat, influences quality perception and consumer acceptability. In this study, the amino acid sequences of Japanese quail and northern bobwhite myoglobin were deduced by cDNA cloning of the coding sequence from mRNA. Japanese quail myoglobin was isolated from quail cardiac muscles, purified ...
