Breeding Program
Brahman & Brangus Breeding
At Tarramba Brahmans & Brangus we recognise the paramount importance of maintaining profitability amidst the diverse and often challenging seasonal conditions that characterize the agricultural landscape.
With years of hands-on experience, we adhere to strict criteria when selecting and selling breeding stock, ensuring that they are suited to real-world conditions and costs.
Our breeding practices are meticulously designed to ensure the production of robust and highly functional cattle that exceed market expectations. Our females undergo yearling mating for 90 days with multiple sires, while our cow herd is joined with multiple sires for 100 days. DNA testing and genomic enhanced EBVs of all calves for parent verification and improved data accuracy further reinforces our commitment to continual genetic improvement, allowing standout animals to emerge while ensuring rigorous culling of non-conceiving individuals.
BreedPlan EBVs
BreedPlan data is actively recorded and applied in our selection process to drive profitability through key traits such as growth and fertility. We believe that a disciplined breeding program—where underperformers are culled and sires are carefully selected—is essential to producing well-adapted, commercially viable cattle. BreedPlan serves as a tool in guiding our herd in the right genetic direction, focusing on traits that are important to both our business and our clients.
Traits recorded include:
- Birth Weight (on IVF calves)
- Accurate birth dates
- 200, 400, and 600 Day Weights
- Mature Cow Weight (MCW)
- Scrotal Size (SS) at 400 days, to identify early puberty
- Percent Normal Sperm (PNS) – morphology data
- Fat Scans: P8 and RIB
- Muscle Scan: Eye Muscle Area (EMA)
- Days to Calving (DTC)
OUR BREEDING PHILOSOPHY
At Tarramba, we believe bulls should look like bulls and cows like cows—feminine cows breed masculine bulls. We focus on functional, profitable genetics, recognising that outstanding traits can be found across all breeds when backed by the right program and data. Our goal is to multiply those traits to help keep farming families on the land.
A quote we think is very relevant to our breeding philosophies,
“As breeding objectives for the major traits are reached, beef cattle selection will require a whole new way of thinking. Rapid genetic change will no longer be important. We will enter a period of new conservatism where extremes are avoided, increasing attention is paid to accuracy of evaluation, and primary emphasis is on preventing mistakes. The genetic gain that does occur will be in the areas of adaptability and convenience and can be expected to be slow”
– Larry Leohart of Shoshone Angus USA in 1980.
Key features of our program:
- Yearling heifers joined for 90 days in multi-sire groups—selecting females that calve at 2 and rebreed for 3-year calving (“Halo” heifers)
- Cow herd joined for 100 days, multiple sires—no single sire “excuses”
- 2-year-old joiner heifers FTAI then multi-sire joined
- PTIC yearlings calve out in mobs—no “special treatment”
- Breeding season: bulls in Nov 1, cows for 100 days, heifers 90 days
- Sires selected on dam fertility, structure, udder quality, and EBVs (growth, temperament, fertility, polledness and colour)
- Whole herd preg-tested at weaning—empties culled, PTICs split into early and late calvers.
