Explanation of Breedplan Figures

Breedplan is a performance recording system which uses an animal’s own performance, plus the performance of all known relatives in
the herd - sire, dam, half sisters and brothers etc.
Breedplan uses Estimated Breeding Values (EBV’s) to rank animals for different traits.
EBV is “The Estimated Value of an Animal as a Parent” expressed in kilograms.
Calving Ease EBVs (%) are based on calving difficulty scores, birth weights and gestation length information. More positive EBVs are
favourable and indicate easier calving.
CE % DIRECT = DIRECT CALVING EASE The EBV for direct calving ease indicates the influence of the sire on calving ease in purebred
females calving at two years of age.
BIRTH WEIGHT EBV (KG) is based on the measured birth weight of progeny, adjusted for dam age. The lower the value the lighter the
calf at birth and the lower the likelihood of a difficult birth. This is particularly important when selecting sires for use over heifers.
200-DAY GROWTH EBV (KG) is calculated from the weight of progeny taken between 80 and 300 days of age. Values are adjusted to
200 days and for age of dam. This EBV is the best single estimate of an animal's genetic merit for growth to early ages.
400-DAY WEIGHT EBV (KG) is calculated from the weight of progeny taken between 301 and 500 days of age, adjusted to 400 days and
for age of dam. This EBV is the best single estimate of an animal's genetic merit for yearling weight.
