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...

The development of genetic markers for animal breeding is an effective strategy to reduce the time and cost required to improve economically important traits. To implement genomic selection in the multibreed chicken population of Korea, an understanding of the linkage disequilibrium (LD) status of the target population is essential. In this study, we performed population genetic analyses to inv...

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, ...

two breeds of chickens were used to develop reference family and detect qtls affecting egg quality traits: cocks of a native polish breed green-legged partidgenous (glp) and hens of rhode island red (rir). during the first 100 days of the laying period, the glp hens lay about 40 eggs weighting on average 50 g, whilst the rir flock laid 83 eggs with a mean weight of 60 g. qtl analysis of egg qua...
