Performance & Genetics
EBVs Made Simple
Understanding genetics doesn't have to be complicated. Discover how Estimated Breeding Values (EBVs) can help you choose the right Charolais cattle for your breeding goals.
What Are EBVs?
An Estimated Breeding Value (EBV) is an estimate of an animal's genetic potential for a particular trait, such as growth, birth weight or carcase quality.
BREEDPLAN uses pedigree and performance records to calculate EBVs, helping breeders and commercial farmers compare animals on their expected genetic merit rather than appearance alone.
Why EBVs matter
Selecting the right bull can influence the performance of future generations. EBVs provide valuable information to help farmers make more informed breeding decisions and choose genetics suited to their production system.
Compare Animals
Evaluate genetic differences between animals using recognised performance measures.
Make Informed Choices
Balance characteristics such as calving ease, growth and carcase quality to meet your breeding objectives.
Commercial Value
Use reliable genetic information to support consistent, long-term breeding progress.
Key EBVs to Understand
Calving Ease EBVs
Calving Ease EBVs help predict genetic differences in the likelihood of unassisted calving. Higher Calving Ease Direct EBVs generally indicate greater potential for calves to be born without assistance, making these values especially important when selecting bulls for heifers.
Birth Weight EBVs
Birth Weight EBVs estimate genetic differences in calf birth weight. Lower values generally indicate lighter calves at birth, which can help when considering calving difficulty. However, birth weight should always be assessed alongside Calving Ease EBVs and other breeding objectives.
Growth EBVs
200, 400 & 600 Days
Growth EBVs estimate genetic differences in liveweight at different stages of development.
- 200 Day Weight: early growth to weaning (~ 6-7 months).
- 400 Day Weight: growth during the post-weaning period (~ 13 months).
- 600 Day Weight: longer-term growth potential towards finishing or maturity (~ 20 months).
Carcase EBVs
Carcase EBVs help assess economically important characteristics, including carcase weight, eye muscle area, fat depth and retail beef yield.
These indicators can help producers select genetics suited to their intended beef markets.
Where do EBVs come from?
EBVs are calculated using a combination of information, including, pedigree records, performance data and, in some cases, genomic information.
The more relevant information available, the more reliable the EBV.

Understanding the Numbers
How to read an EBV
EBVs are expressed in the units used to measure each trait, such as kilograms for weight or percentages for some other characteristics. They describe estimated genetic differences, not guaranteed physical measurements. The accuracy of an EBV also matters, as it indicates how much confidence can be placed in the estimate.
