Appreciated for their versatile nutritive value and functional properties, eggs are considered as an important item in human diet. Eggs are one of the most common foods available worldwide as they play an important role in human diet by providing humans with protein, lipids, minerals and vitamins in an adequate amount. Chicken breeds differ in physical and biochemical contents in terms of eggs ...

Phenotypic measurements of chicken egg character and production traits are restricted to mature females only. Marker assisted selection of immature chickens using quantitative trait loci (QTL) has the potential to accelerate the genetic improvement of these traits in the chicken population. The QTL for 12 traits (i.e. body weight (BW), six for egg character, three for egg shell colour and two f...

In this study, 21 microsatellite markers were used to genotype 196 Egyptian local chickens obtained from Fayoumi (n = 35), Dandarawy (n = 30), Baladi (n = 29), Sinai (n = 30), El-Salam (n = 36), and Golden Montazah (n = 36) strains. The results were compared to two pure commercial chicken populations reared in Japan-White Leghorn (n = 42) and Rhode Island Red (n = 43). A total of 162 alleles we...

Chromomeres 1 and 3 of the chicken W lampbrush chromosome contain most of the EcoRI and XhoI repeat sequence families respectively. These chromomeres were stained with DAPI and their sizes relative to other W chromomeres were observed. Their relative contents of EcoRI and XhoI repeats were determined using ̄uorescence in situ hybridization with genomic probes for each of the two repeat families....

The theme of this issue is “Collaboration for Quality”. Medical errors have been attracting increasing attention since the Institute of Medicine’s initial publication in 1999. In this issue, Dr. Harry Sax discusses lessons learned from the aviation industry on checklists. Collaboration on checklist development and dissemination has brought these lessons to practitioners throughout the state. Qu...

Although co-payments and deductibles are means of keeping health expenditures low, they have also been cited as barriers that inhibit patients from accessing necessary healthcare. We aimed to evaluate Rhode Island residents' experiences with cost-related access challenges within the state's healthcare system. We conducted a cross-sectional survey of resident experiences with healthcare in Rhode...

OBJECTIVES Compare the prevalence of recent alcohol, tobacco, and drug use among patients from two Rhode Island emergency departments (EDs) to Rhode Island state and United States national general population estimates between 2010 and 2012. METHODS Secondary analysis of ED patient data and the National Survey of Drug Use and Health. RESULTS Alcohol was the most commonly reported substance, ...

T HAS been shown by grafting potential melanophores from one embryo to I another of a genetically different breed of fowl or species of bird that the color or color pattern produced in the host feather is invariably like that of the donor breed or species (RAWLES 1939; WILLIER and RAWLES 1940). In other words, the coloration or color pattern produced seems to depend upon the genotypic constitut...

Benda V., A. Hampl, Katefina Trtkova: Evaluation of W'attle Reaction and Antibody Response in Different Chicken Breeds. Acta vet. Bmo, 59, 1990: 151-156. The intensity and kinetics of antibody production as well as wattle reaction to the natural antigens with different thymus dependence in adult birds of two layer breeds White Leghors (WL) and Rhode Island Red (RIR) were investigated. The breed...
