| QTL Experiment in Brief |
|---|
| Animals: | Seven full-sib families including 222 offspring from a broodstock population at the NCCCWA in Leetown, West Virginia, USA, were used for QTL mapping. |
| Breeds associated:
n/a
|
| Design: | Two stress response phenotypes were used for QTL analyses. First, we estimated animal breeding value (EBV) using four repeated measurements of plasma cortisol and fitting a mixed inheritance linear model under a Bayesian framework with software iBay version 1.46. We also estimated an animal effect using best linear unbiased prediction (BLUP) and fitting four repeated measurements of plasma cortisol in a multivariate mixed model with the software ASReml version 2.0. |
| Analysis: | We performed combined sire-family (five HS (half-sib) families) and dam-family (seven HS families) HS regression analysis, separately. We also performed a genome scan for genetic loci linked to stress response phenotypes (animal BLUP index and EBV for plasma cortisol) using a variance components (VARCOMP) method. |
| Software: | GridQTL and SOLAR version 4.0 |
