QTL Experiment in Brief |
Animals: | Animals were Italian Holstein cows in their first, second, or third parity. |
Breeds associated:
|
Design: | Animals were genotyped using the Illumina BovineSNP50 BeadChip and analyzed for heat stress tolerance based on milk production traits. A total of 45,546 SNPs were used for analysis. |
Analysis: | A genome-wide scan was performed on PCA scores using the GRAMMAR procedure. |
Software: | GenABEL in R, SAS, AIREML90 |
