Twynam has a long history in Agriculture and today is run by Johnny Kahlbetzer. Read Twynam's story here.


Twynam’s agricultural interests today operate across the two properties, “Wingello Park” and “Johnniefelds”, near Marulan, NSW, Australia where we excel at breeding exceptional cattle and polo ponies in a regenerative manner. We are implementing management practices focused on pasture management with minimal chemical inputs and intensive rotational grazing to provide better and healthier pastures which will increase the carbon content of our soils and provide our animals with a better nutritional profile.

We are selling 30 R bulls and 10 Q bulls on Auctions Plus on Tuesday, 14 September 2021. 

Bulls can be inspected at “Wingello Park”, Marulan on the 12-13th September. 

Catalogue Coming out on the 15 August 2021, or contact Luke Gleeson at



Twynam Angus have sold bulls across Australia and our genetics are proven to work in Southern Australia as well as in the tropical and arid environments in Queensland and the Northern Territory.


"We have Twynam Angus bulls working very well on our stations in NT and Qld. They handle very tough conditions while producing quality calves for both feedlot markets and replacement females. We were fortunate enough to purchase stud females from the Tywnam Angus stud reduction sale. These females are performing very well in our stud operations in central Queensland. They have handled the hot conditions as well as pressure from parasitic ticks very well. The quality of their calves is top shelf. 

The Twynam Angus bulls we have working for us in Qld and NT are producing great heifer calves that we will keep in our breeding program and steers that are performing very well on grass and in the feedlot. Having worked for Twynam for 10 years, since I graduated from University, I knew first hand the ruthless objective selection pressure that the Twynam Angus stud and commercial herd was put under and this gave me great confidence to purchase Twynam genetics for the CPC stud and commercial herds.”


Troy Setter,CEO,

Consolidated Pastoral Company (Australia’s largest private beef producer, with stations in Qld, NT and WA and 2 feedlots in Indonesia).


The Twynam Angus stud has been registered since 1992. It was originally started to produce bulls for Twynam’s commercial needs. At the stud’s peak it had 2,000 cows producing bulls for 20,000 commercial cows whose progeny was aimed at the Japanese export market.

With our very clear focus to produce bulls that support profitable production we are well aware of the importance of having males and females that can walk well, successfully breed for many years and produce progeny that meet the market requirements.

Today we emphasise marbling with growth and the end results of this can be seen in our Breedplan figures. Our R drop (2020) bull calves have the second highest Heavy Grain index and the highest IMF amongst all major Australian Angus studs, to the best of our research.

Twynam has had experience with other breeds of cattle, apart from Angus. When we acquired Naroo Pastoral company in 1979 we inherited a Santa Gertrudis stud and a large number of Santa commercial cows. In the early 1990’s we added Red Angus and Gelbvieh into the mix. We were very impressed with the cattle however the base infertility in our Santa cows caused us to do a wholesale switch to black Angus across all the Twynam properties.


Today we are embarking on a journey back into composites. The image of those calves won’t leave me alone!

Our first calves on the road to our composite are being born this spring, 2021. Next year we will have Angus and cross bred bulls available for sale. 



We believe that the cattle industry needs to be much more proactive on its carbon emissions footprint than is currently being addressed. In our effort to get on the front foot we have analysed the important factors that drive the emissions profile of the industry. 

The most basic aspects revolve around having only productive animals on farm. If you aim to slaughter an animal at 2 years of age but you keep it until 3 years, then that animal will emit 50% more carbon than it should have. If a heifer is joined at 2 years of age instead of one year of age, then she carries a whole extra year of carbon emissions with no production. Let’s assume that you keep your cows until they have a calf at 7 years of age and that the progeny are all sold at 300kg. You have 2 cows, one has her first calf at 2 years old and calves every year thereafter. Another cow calves at 3 years old and misses a calf along the way but you still keep her in the herd. The first cow will produce 6 calves (1,800kg of animal) while the second cow will produce 4 calves (1,200kg) in their lifetimes. The first cow is 50% more carbon efficient than the second cow!!

A big cow will eat more and hence emit more carbon than a smaller cow. What’s the best weight? There is no simple answer but smaller cows that wean a larger percentage of their body weight are in the lead. However we do need to keep in mind what the market requires as an end weight that the meatworks can efficiently process. Twynam's thoughts are that 550-650kg cows are where we should be. So don’t just buy the biggest bull in a sale catalogue. A study showed that there was nearly a 100% correlation between bull weight and the price paid at bull sales. That means that every heavier bull sold for more than a lighter bull. So not only do buyers spend more on heavier weight bulls, but in a self-replacing breeding program they also have to spend more on feeding each cow than if they selected more moderate mature cow weight genetics.  This is not just costly economically, but also incurs a higher environmental cost.



Twynam is also working very hard to use genetics to improve environmental efficiency.  We have been feed efficiency testing our last 4 calf crops at the Tullimba feedlot at Armidale, which makes us the leader in Australia for this measuring this trait in Angus. We hope to start to see the benefits of this work as of our ‘S’ drop calves being born in 2021.  Research confirms that selecting for low net feed intake also results in selecting for lower methane emissions. Accordingly, by breeding cattle with better feed efficiency, we can support the commercial cattle industry to reduce costs of the production at the same time as reducing environmental costs by reducing methane emissions per animal and per hectare.


In order to test the effectiveness of our program, we are after some cooperative breeders to produce progeny from our selected bulls. We would provide the bulls, buy back the male progeny at weaning, after which we will feed efficiency test them and then take them through for kill data, which we will share. All the animals will be Genomic tested and parent verified. We are after minimum cow herd size of 200, to enable useful cohort group sizes. Please contact us if you have any interest.
