Calculation formula for using the above breeding value of each individual
in relation to the reference carbon emission information
Y = Xb + Zu + e
  • Y : Meat production by individual
  • X : Environmental effect information
  • Z : Genome information
  • b : fixed effect vector
  • u : breeder vector
  • e : error vector

Superior breeding genome analysis

Distribution of genetic capacity of cow herds by farm (example)
: 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
Set a target of 90% or more in the future through continuous R&D
from 70% of the current superior breeding object prediction accuracy
