– Data acquired directly from a diverse group of collaborating
herds and from multiple sources
– Based on information from dairy producers, for dairy
producers

• RWD acquired directly
from collaborating herds
– Collected via dairy herd
records software programs,
such as DairyComp 305 and
PCDART.
ABS RWD Bull Fertility
Data Sources
• By 2012, more than 12 million inseminations
representing 10,000 dairy sires included in
the ABS database
– Large data pool provides extremely accurate fertility
estimates on ABS sires and early detection of
ABS Pregnancy Kings
ABS RWD Bull Fertility
Data Sources
• Initial data compiled from U.S. sources.
– Additional data are being collected from U.S., Mexico, UK, Italy,
Chile, Brazil and Argentina, with plans to incorporate in the
future
– Data from all sources with dairy records software compatible
with the ABS database are being accepted
ABS RWD Bull Fertility Rankings
• A 1- to 5-star ranking scale is applied across active
ABS bulls
– ABS publishes data for bulls with more than 250
conventional inseminations, from at least 4 herds
• A typical benchmark of 90% reliability requires
2,100+ inseminations
• Holsteins and Jerseys rated separately: no crossbreeding
data used currently
ABS RWD Bull Fertility Rankings
• Star rankings:
– 10% 2-3% points above average fertility
– 20%
– 40% Average fertility
– 20%
– 10% 2-3% points below average fertility
•
ABS Pregnancy Kings: 4 or 5 star ranking based
on 1,000+ inseminations
ABS RWD Bull Fertility Analyses
• Analyses completed in-house using ABS proprietary
processes
– Evaluations include only confirmed pregnancy events
– RWD Bull Fertility model accounts for:
• Age of the cow, as lactation number
• Stage of lactation, as service number or times bred
• Management and environmental related differences, as herd-yearseason effects
– Only lactating cow breedings are accounted for in the
conventional evaluations
– ABS Sexation® evaluation includes heifer breedings only

genetic potential and bull fertility of ABS Sires
