As the Greenup family prepares to celebrate their 66th estate bull sale this year, they remain committed to breeding high yielding, productive Santa Gertrudis cattle that perform in a variety of environments.

Now Australia’s longest running estate bull sale, David and Sonya Greenup and their family will be offering 145 bulls and three pregnancy tested heifers at their Rosevale, Jandowae property on Tuesday 20 September. The sale will also be linked to AuctionsPlus, allowing potential buyers from around the country to bid.

According to Mr Greenup, increasing kilograms per hectare with a focus on herd productivity has been at the heart of all breeding decisions by breeders for more than 30 years.

He said the Rosevale herd was one of the largest and most accurately recorded in northern Australia.

“The Santa Gertrudis Group Breedplan is used to help identify and breed animals that are genetically superior for a wide range of traits,” he said.

“This results in high-yielding genetics being stacked on top of each other, leading to consistently predictable results for traits that affect beef herd profitability.”

Confirming the consistent quality of their genetics, this year’s draft of Rosevale bulls has an Estimated Breeding Value to Calving of -6.9 days with 84 young bulls ranking in the top 25 percent of the Santa Gertrudis breed for this trait.

This year’s sale catalog also features 89 bulls ranked in the top 25% of the Export Production $Index, which is derived from a combination of fertility, growth and carcass traits.

The Export Production $Index, for example, estimates genetic differences between animals in net profitability per cow combining a self-replacing commercial herd targeting pasture-raised steers and steers ready for export.

“The $Indices are very powerful metrics that combine all the EBVs that contribute to profitability into one simple dollar value,” said Mr. Greenup.

But Mr Greenup also emphasized that as well as improving performance, the breed continued to focus on producing commercially oriented bulls with proven longevity.

The Greens have a policy of taking their bulls out of pasture to ensure they can easily acclimate to their new home, regardless of the country or season they are traveling to.

“Because of their sound and healthy upbringing, they have longer working lives, which makes them extremely good value for money,” Mr Greenup said.

“We expect our bulls to do the job from day one.”

Mr Greenup said pregnancy rates in the cow herd had been kept at 90 per cent despite Rosevale receiving three-quarters of its average annual rainfall over the past five years. With the improvement of seasonal conditions last year, the results in 2022 were higher.

“This type of reproductive continuity is one of the main reasons for the adoption of our cattle.

“Many of our customers run cattle in tougher conditions than we do, so putting the pressure on our herd to perform ensures that our bulls deliver results in their herds no matter where they are.”

The Greenup family takes a long-term view and as a result has a loyal customer base. They currently sell over 400 Rosevale bulls annually across Qld and NSW, with interest also coming from WA, SA and the Northern Territory.

“Buyers often comment on the ability of our bulls in their first season and are surprised at how much the bulls grow as they mature on the track,” Mr Greenup said.

“We are not surprised by these comments as the Breedplan EBVs of these bulls predict higher growth than their sales weights indicate. Our selection for high yielding females has created a herd of animals that do well with ‘efficient motors’.”

Mr Greenup said cattle producers should understand all the information Rosevale has to offer.

“By focusing on the areas that matter most to them, they can select bulls with the confidence that our balanced approach will take care of the rest.”
