The Science Behind Superior Genetics
When investing in rams for your breeding program, data-driven decisions separate profitable operations from costly mistakes. As a fourth-generation Border Leicester breeder and SuperBorders founding member, I’ve witnessed first hand how objective genetic measurement transforms commercial success.
What Makes a SuperBorder?
SuperBorders aren’t just another marketing term—they represent Border Leicester rams ranked by LAMBPLAN as above the 50th percentile for the breed using the BLX (Border Leicester Cross) Index. The cut off is determined after the 15th of August each year.
Meaning every SuperBorder eligible ram delivers measurable genetic above average for first-cross production systems.
The BLX Index combines multiple ASBVs into one over all score, the index. It accounts for the ram’s contribution to lamb growth (50% attribution to first-cross progeny, 25% to second-cross), maternal weaning weight improvements, birth weight, growth, fat depth and fertility gains. Think of it as your ram’s earning potential translated into hard numbers.
Reading the Numbers That Matter
Our 2025 rams showcase consistent genetic progress. Our rams are consistently improving every year while still maintaining the visual traits that our family has always wanted.
Key traits driving these returns include:
- Maternal Weaning Weight (MWWT): Higher values mean more milk production and better mothering ability in first-cross daughters
- Post Weaning Weight (PWWT): Translates to faster-growing lambs reaching market weight sooner
- Weaning Rate (WR): The new improved fertility measure combining conception, litter size, and rearing ability
The Womboota advantage
Our genetic trend analysis shows consistent improvement across all economically important traits. We’re not chasing extreme values that compromise constitution—instead, we’re building balanced genetics that perform in commercial conditions.
When first-cross ewes are commanding $400-500 per head in strong markets, the genetics behind those ewes becomes crucial. SuperBorders provide that genetic foundation, backed by independent LAMBPLAN verification.
Making Informed Decisions
Don’t let impressive marketing overshadow genetic facts. Demand to see the percentile rankings, accuracy figures, and genetic trends.
At Womboota, we’re proud to share this data because it demonstrates our commitment to genuine genetic progress. Remember: the genetics you buy today will still be working in your flock for years to come. Invest in proven performers, not genetic lottery tickets.
