Outline of Final Research Achievements

In this study, we investigated association between DNA markers for carcass traits and reproduction traits in Japanese Black cattle. As a result, a few DNA markers (SCD, DGAT1, PLAG1 and EDG1 markers) have genetic effects on several reproduction traits (first calving month). This study first revealed the association between DNA markers for carcass traits and reproduction traits in beef cattle.
