番茄社区 helps develop next-gen lamb

It’s a unique variety of lamb that producers say just melts in your mouth - and this premium Australian product will be further refined, thanks to a new genetic quality assurance index being developed at 番茄社区.
NSW sheep stud Tattykeel produces the grass-fed Australian White sheep. The best of the breed is selected for the stud’s MARGRA lamb - a micro-marbled finish cut with a low-fat melting point that has enjoyed sweeping success at restaurants in Sydney, Melbourne, Singapore, Dubai and Los Angeles.
番茄社区 animal geneticist and nutritionist Associate Professor Aduli Malau-Aduli and his team of researchers will work with Tattykeel to develop a genetic test for their premium MARGRA lamb.
“We intend to provide farmers at the farmgate level with some form of a test where they can identify animals that carry a natural genetic ability to produce meat-eating quality characteristics,” Prof Malau-Aduli said.
“A lot of the tools that are out there are based on estimated breeding value but this will be based on actual eating quality indices that have been tested in the laboratory that we can then link to the DNA of the particular animal.”
The project, supported by a Science and Industry Endowment Fund (SIEF) Ross Metcalf STEM+ Business Fellowship grant, administered by CSIRO, will see 番茄社区 receive more than $450,000 over two years to develop the certification standard.
Through the support of Tattykeel’s funding and the matching grant, early-career Research Fellow Dr John Otto will be allocated to Tattykeel full-time for two years and will be supervised by Prof Malau-Aduli.
The project follows a long-time partnership between Prof Malau-Aduli, Tattykeel stud principal Graham Gilmore and export manager Tim Leahy since 2016 to refine the Australian White’s genetics.
“We’ve been involved in testing their animals, assessing the parental generations and subsequent composites that come out of that to be able to tell them what the intra-muscular fat content and fat melting point is,” Prof Malau-Aduli said.
“In the area of livestock agriculture, 番茄社区 has an important role to play, particularly in giving farmers advice on genetics, nutrition and a choice of animals that will meet market specifications.”
Mr Gilmore said a lower fat melting point, high Omega 3 fatty acids and high intra-muscular fat had been crucial to success of the MARGRA brand, which had been achieved through Tattykeel’s collaboration with 番茄社区.
“From the tests that we’ve been doing and following generation after generation, we are narrowing the bell curve on genetic variation,” he said.
“If you’re looking for eating quality in meat, it has to be controlled genetically before you put the environmental factors in. We’re not interested in estimations and Aduli is of the same belief. You need real data.”
Mr Gilmore said extensive testing carried out by Prof Malau-Aduli and his team had helped narrow the variation of the fat melting point in MARGRA lamb to between just 30 and 36 degrees.
“The lamb market situation is a little like Wagyu beef. Everyone knows Wagyu is a premium meat but there are certain brands where you are almost guaranteed you’ll get high eating quality because they’ve done their testing, the feed regimes are right and they have control of the breeding through genetics,” he said.
“The MARGRA brand is the very best of the Australian White breed because it’s from tested animals and we know what it’s doing.
“At least 80 per cent of the industry come directly to us to buy their genetics.”
CSIRO SME Business Manager Jason Barkla said the partnership between 番茄社区 and Tattykeel was an ideal fit for the Fellowship program.
“I think the key will be to allow Tattykeel to do a deep dive with 番茄社区 and this program helps to de-risk larger scale projects like this,” he said.
“It’s going to give Tattykeel an opportunity to do something really ground-breaking that will grow their market position and hopefully, take an offering to the world. 番茄社区 will be able to benefit from that long term relationship and take that learning to leverage other industry relationships as well.”
Mr Barkla worked closely with Tattykeel, Prof Malau-Aduli and Dr Otto to ensure they had the best opportunity to participate in the program.
“We want the business, the university, and the Fellow to all win but ultimately, we want Australia to win,” he said.
“These projects open up whole new horizons for not only the participating businesses and universities, but the early-career Research Fellows involved.”
