Leading Stock Sires for Maternal Traits
• Age at First Calving GEBV/EBV (days): indicates genetic potential for heifers to hold to first service opportunity.
Look for negative values (ie less days) for heifers with genetic potential to hold to first service.
• Calving Interval GEBV/EBV (days): indicates genetic potential for the time that cows take to get back in calf. Look
for negative values (ie less days) for cows with genetic potential to get back in calf on time.
• Longevity GEBV/EBV: indicates genetic potential for the relative number of calves born in a dam’s lifetime. Look
for positive values for cows with genetic potential to be more productive in the herd.
• 200 day Milk EBV: indicates the genetic potential for the maternal component of growth at 200 days of age (ie the
contribution that the milking and maternal abilities of a bull’s daughters make towards their calves’ growth at 200
days of age). Look for high positive value for daughters with potential to wean heavier calves.
• Maternal Calving Ease EBV: indicates the genetic potential of a bull’s daughters to calve easily. Look for positive
values (ie more unassisted calvings) for daughters with potential to calve more easily.
• Beef Value (index): a weighted index incorporating the EBVs for 400 day growth, muscle depth, fat depth, birth
weight and calving ease.
The league table below details the current Top 10 Limousin stock bulls for Age at First Calving GEBV/EBV (where
accuracy is equal to or greater than 50%) that also meet the following criteria:
• All bulls also have EBVs/GEBVs above breed average for Calving Interval, Longevity, 200 Day Milk, Maternal Calving
Ease, Calf Survival and Beef Value.
• All bulls have sired a registered calf within the last two years (since 01/03/2021)
Animals are listed by their Age at First Calving breeding value in descending order. Accuracy values are shown as
% alongside each breeding value.
