| Summary: | <p>Carcass traits have been efficiently improved by recent selection using DNA
markers in beef cattle. Additionally, DNA markers might have an effect on other
traits such as fertility traits; therefore attention should also be paid
to such pleiotropic effects. However, the effects of the markers on both
carcass and fertility traits have never been evaluated in the same
population, since they are generally measured in different populations. The
objective in the current study was to discuss effectiveness of DNA markers
developed for carcass traits through investigation of their effects on
carcass and fertility traits in a population. We genotyped six markers <i>SCD</i>
V293A, <i>FASN</i> g.841G>C, <i>PLAG1</i> g.49066C>G, <i>NCAPG</i> I442M, <i>DGAT1</i> K232A, and
<i>EDG1</i> g.1471620G>T in a Japanese Black cattle population (<span class="inline-formula"><i>n</i>=515</span>). To
investigate their effects on carcass and fertility traits, we performed
statistical analysis (ANOVA and the Tukey–Kramer honestly significant difference (HSD) test). In the results,
three of six markers, <i>SCD</i> V293A, <i>NCAPG</i> I442M, and <i>EGD1</i> g.1471620G>T, were
significantly associated with both carcass and fertility traits.
Remarkably, the same allele for each marker had positive effects on both
traits, suggesting that we would be able to simultaneously improve them
using these markers in this population. However, previous studies reported
that the effects of DNA markers could differ among populations. Therefore,
it is necessary to confirm the effect of the marker in each population
before it is used for improvement.</p> |
