Superior breeding genome analysis
Distribution of genetic capacity of cow herds by farm (example)
: Analysis of genetic factors for carbon emissions and intramuscular fat
: Analysis of genetic factors for carbon emissions and intramuscular fat
Criteria: Genetic ability is high when the standard breeding value distribution by trait (total including females and males) is 0 or more
