A Genome Scan for Quantitative Trait Locus by Environment Interactions for Production Traits [PDF]
Journal of Dairy Science, 2007 Genotype by environment interactions between milk production traits and production level have often been observed. To increase the power of quantitative trait loci (QTL) detection, QTL by environment interaction was included in QTL analyses for the milk, protein, and fat yields.

Identification of Quantitative Trait Loci for Production Traits in Commercial Pig Populations [PDF]
Genetics, 2003 Abstract The aim of this study was to investigate methods for detecting QTL in outbred commercial pig populations. Several QTL for back fat and growth rate, previously detected in experimental resource populations, were examined for segregation in 10 different populations.

Impact of environmental temperature on production traits in pigs [PDF]
Scientific Reports, 2020 AbstractThere is an urgent need to identify the effects of temperature on production traits. This study aimed to determine the impact of pig production in three environments (T°Cgrowing-°Cfattening-°Cfinishing = T24-24-21, T19-19-19, and T23-17-15) on growth curve parameters, body weight gain (DBWG), feed intake (DFI), and feed efficiency during the ...

IDENTIFICATION OF QTL FOR PRODUCTION TRAITS IN CHICKENS
Animal Biotechnology, 2005 If the poultry industry hopes to continue to flourish, the identification of potential quantitative trait loci (QTL) for production-related traits must be pursued This remains true despite the sequencing of the chicken genome. In view of this need, a scan of the chicken genome using 72 microsatellite markers was carried out on a meat-type x egg-type ...
