The mature body condition EBV advantage
AngusPRO has unlocked the genetic potential for feed efficiency and reproductive success with the introduction of the Mature Body Condition (MBC) EBV. Words Sarah Horrocks.
By selecting bulls with positive values for this trait, you’re investing in cow families that will thrive in your environment while reducing production costs and improving reproductive performance.
The introduction of the Mature Body Condition EBV represents one of the most significant advancements in Angus genetic evaluation in recent years. This powerful tool, used exclusively by Angus Australia (AngusPRO) breeders here in New Zealand, allows producers to select for cows that will have improved body condition scores (BCS) at weaning, directly impacting profitability and herd sustainability. It’s important to note that the EBV provided by Angus Australia is genomically enhanced and has a very strong reference population. Within the Angus Australia database, there are more than 68,800 animals that have a phenotypic score for body condition, including females in the Angus Sire Benchmarking Program (ASBP). The greater the reference population, the greater the accuracy. MBC predicts the genetic tendency for a bull’s daughters to maintain BCS throughout lactation to weaning. This trait reflects the cow’s inherent ability to partition nutrients efficiently between maintenance, lactation and reproduction – essentially measuring metabolic efficiency at the cow level.
Cows with higher MBC EBVs possess the genetic potential to maintain adequate flesh while meeting the energy demands of milk production and reproduction. This genetic advantage typically translates into improved rebreeding rates and shorter calving intervals, greater resilience during drought or poor pasture conditions and enhanced longevity and lifetime productivity. There are also lower overall production costs per calf weaned.
Research consistently shows that cows maintaining BCS 5 or above (Beef + Lamb New Zealand system) have significantly higher conception rates.
The economic value of improved body condition maintenance is substantial. Studies indicate that cows with superior body condition genetics can increase weaning rates, extend productive life and improve overall herd profitability.
These improvements compound over time, making the MBC EBV one of the most economically important traits for commercial operations.
