Polychlorinated biphenyls (PCBs) decrease thyroid function in laboratory rodents by inducing activity of a liver enzyme, uridine diphosphate-glucuronosyltransferase (UDP-GT), thereby increasing thyroxine (T4) clearance. This loss of T4 can lead to hypothyroidism. In this study, an assay was validated for measuring UDP-GT activity toward T4 in Japanese quail. UDP-GT induction by Aroclor 1254 was...

The objectives of this experiment were to study the effects of different environmental temperatures during the rearing phase on the heat tolerance and behavioral responses of two Japanese quail lines to heat stress. A total of 192 chicks from two lines were randomly distributed between eight brooding cages. Each line was divided into 4 treatments. Each treatment was different in experimental pe...

The restriction fragment length polymorphisms (RFLP) of the Japanese quail MHC were assayed in seven lines using PvuII-digested DNA and a chicken Class II probe. The lines of Japanese quail surveyed included a randombred control population (R1) and sublines of R1 divergently selected for 4-wk body weight (HW and LW lines) or plasma yolk precursor as measured by total plasma phosphorus (TPP) (HP...

AIM To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh. MATERIALS AND METHODS The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 ...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes and phylogenetic gr...

The purposes of this study were to develop a probe for the detection of thyroid-stimulating hormone (TSH) beta subunit mRNA, to validate the usefulness of that probe in measuring TSH, and to use it to investigate the effects of thyroid suppression on TSH and the reproductive axis in Japanese quail. The objectives of experiment 1 were to isolate and characterize a partial cDNA for quail TSH and ...

The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...

the present study was conducted to investigate the effect of corn substitution with triticale in grower diets (zero, 50 and 100%) with/without exogenous enzyme supplementation on growth performance, digestive organs relative weight, jejunal morphology and blood lipids of quail chicks. two hundred and forty one-day-old unsexed japanese quail chicks were randomly assigned to a completely randomiz...

ERUM albumin polymorphism has been reported in such animals as pigs (KRISTJANSSON 1963), horses (STORMONT and SUZUKI 1963), cattle (ASHTON 1964; ASHTON and LAMPKIN 1965), chickens (MCINDOE 1962) and turkeys ( QUINTEROS, STEVENS, TORMONT and ASMUNDSON 1964). BECKMAN, CONTERIO and MAINARDI (1963) examined the serum protein patterns of avian species hybrids and found that in eight out of 11 inters...
