Chickens display a wide spectrum of phenotypic variations in quantitative traits such as egg-
related traits. Quantitative trait locus (QTL) analysis is a statistical method used to …

Phenotypic measurements of chicken egg character and production traits are restricted to
mature females only. Marker assisted selection of immature chickens using quantitative trait …

We performed quantitative trait locus (QTL) analyses for egg production traits, including age
at first egg (AFE) and egg production rates (EPR) measured every 4 weeks from 22 to 62 …

Quantitative trait loci (QTLs) analyses for internal egg quality of chickens were performed
with 143 microsatellite markers on 27 linkage groups in 371 F2 hens obtained from an …

Expression of 12 positional candidates for QTL affecting shell thickness at 53 wk of lay age
(ST53) was investigated by real-time PCR in the distal part of chicken oviducts (uterus) with …

Исследование выявило мажорный QTL (локус количественных признаков) на
хромосоме 4 кур породы род-айленд с плейотропным эффектом на признаки яйца …

The risk posed by food borne pathogens in eggs has taken on a high priority for government
and consumer. In Europe there has been concern that plans to move from battery cages may …

MATERIALS AND METHODS Twenty four birds randomly chosen from the selected and
control line of RIR chicken maintained at experimental layer farm of ICAR-Central Avian …

Previous research on mapping QTL in a reference family of laying hens indicated that 5
microsatellite loci (MCW0133, MCW0170, MCW0114, MCW0139, and LEI0074) were …

Identification of genes determining the expression of economically important traits of plants
and animals is a main research focus in agricultural genomics. Most of these traits are …
