Tóm tắt

SummaryThe aim of the study was to investigate quantitative trait loci (QTL) in previously identified regions of chicken chromosomes 1, 4 and 5 relating to 40‐day body weights and conformation scores. Half‐sib (HS) and variance component analyses were implemented and compared using QTL Express software. Data were from a two‐generation design and consisted of 100 dam families nested in 46 sire families with trait values for 2708 offspring. Chicken chromosome 4 showed nominal significance for QTL affecting body weight and conformation, and linkage was confirmed for both traits on chromosome 5. Results varied according to method of analysis and with common parent in the HS method.
