As a part of the Australian Agricultural Co’s two hundredth anniversary this 12 months, Beef Central is publishing a sequence of articles on the world’s largest cattle producer’s beef genetics historical past. On this four-part sequence, we’re chronicling AA Co’s development by way of its Shorthorn, Santa Gertrudis, Composite and Wagyu eras. At present’s third instalment appears to be like on the Composite period.

Composite-bred cattle on AA Co’s Barkly nation
JUST because the Australian Agricultural Co had moved from its authentic roots in Shorthorn genetics to Santa Gertrudis within the Nineteen Seventies for productiveness causes, a brand new genetic path arrived for the corporate within the Nineties.
A part of the catalyst was the institution of the corporate’s first feedlot at Meteor Downs, close to Comet in Central Queensland in 1990.
The corporate additionally held custom-feeding house at plenty of different giant Queensland feedyards on the time, and later in 2002, bought a second feedlot at Aronui, close to Dalby.
AA Co had a footprint within the grain-finishing sector lengthy earlier than most giant northern pastoral operators, apart from the North Australian Pastoral Co, which had established a small feedot at Wainui close to Bowenville in 1957.
With a imaginative and prescient rising to retain possession of grainfed cattle additional by way of the availability chain, abruptly, meat high quality was re-positioned as a higher precedence throughout the AA Co’s breeding operations.
Pretty much as good as AA Co’s huge Santa and Brahman herds have been, the corporate might see meat high quality efficiency and fertility alternative within the institution of a composite beef herd, and the corporate’s advances into lotfeeding solely heightened the curiosity.
It might be argued that the identical motivation – persevering with to maneuver up the meat high quality scale – has pushed the corporate’s ultimate genetics period, in Wagyu (ultimate story on this sequence to return)
Executed effectively, a large-scale composite breeding program might harness nearly all of the ‘free-kick’ hybrid vigour impact obtainable in basic terminal crossbreeding, with out all of the related administration hassles, analysis had proven.
The transfer into composite breeding occurred in plenty of phases, beginning within the early Nineties.
Simply previous to the appearance of the composite breeding initiatives, AA Co put Black Angus bulls over Santa cows on its Headingly station southwest of Mt Isa, to provide a terminal cross animal. Additional north at Austral Downs close to Camooweal, an analogous program noticed Charolais bulls over Santa cows in a terminal cross, to undergo the lately bought Goonoo feedlot.
Elsewhere the corporate imported 5 Senepol bulls (tropically tailored Bos Taurus) from the US to be used over elite Santa cows at Brunette Downs, at one time changing into one of many largest Senepol breeders in Australia.
The primary true, methodical composite breeding program didn’t emerge till just a few years later.
In 1999, as a part of its 175th birthday celebrations, AA Co commissioned an organization historical past, titled “In Good Firm.”
In it, a passage refers back to the institution in 1994 of a 1000 head synthetic breeding centre at Meteor Downs on Queensland’s Central Highlands – on the time the biggest such breeding facility in Australia.
“It was determined to develop two composite breeds – one for the Barkly and the opposite for the Gulf stations, which led to the sale of the Santa Gertrudis stud in 1997,” the booklet stated.
“The purpose of the composite program was to develop a tropically-adapted breed-type, producing glorious consuming high quality beef with some marbling potential, whereas retaining heterosis (hybrid vigour) to enhance progress, carcase yield and fertility,” it stated.
Charolais and Crimson Angus semen was used over Brahman cows in synthetic insemination applications to provide the primary cross, the doc stated. “These F1s have been reciprocally crossed with tailored breeds reminiscent of Senepol, Tuli, Belmont Crimson, and Bonsmara to create an animal with improved consuming high quality traits whereas retaining adaptability to northern Gulf circumstances.”
This composite was in flip used over first-cross Santa x Senepol females to provide the softer composite appropriate for the Barkly area.
A part of AA Co’s push into composite genetics coincided with its launch of the 1824 100-day grainfed branded beef program – nonetheless arguably among the many largest and most formidable (funding and advertising and marketing smart) beef manufacturers within the trade’s historical past. The corporate additionally purchased a big meat portioning, value-adding and distribution enterprise in Brisbane as a part of its push additional alongside the value-chain.
After appreciable analysis (genetics advisor Don Nicol labored intently with AA Co for a few years in this system’s growth) two separate composite applications have been developed.
The softer Barkly composite had a Santa base, with principally Senepol and Charolais genetics, whereas the Gulf composite had a better Indicus content material from the muse Brahman breeders, with Charolais and Senepol, some with a splash of Crimson Angus.

Managers struggled with genetic redirection
Nevertheless, as occurred throughout firm’s authentic transfer from its Shorthorn roots into Santas within the Nineteen Seventies, there was some push-back from property managers and others who have been reluctant to desert their much-loved Santa and Brahman straightbred herds.
“Some managers actually struggled with the transformation,” stated Geoff Wagstaff, who spent 26 years as a senior supervisor with AA Co from 1979 recollects.
“Everybody was so pleased with their massive runs of even pink steers, walked off the Barkly right down to South Galwey or Brighton Downs within the Channels,” he stated.
“In these days, coat color was vital. Workers took quite a lot of satisfaction in producing a giant run of peas-in-a-pod pink Santa cattle. There was a way of satisfaction, however color modified in a short time when the composite bulls arrived,” he stated.
The Barkly herds have been nonetheless predominantly Santa-based within the early 2000s, however step by step the herd kind developed as the brand new composite program kicked in.
“The burden of the primary rounds of composite cattle didn’t change a lot from the sooner Santas, however the consuming high quality efficiency (particularly marbling) did,” Mr Wagstaff stated
He agreed that the calving proportion efficiency being recorded by the sooner North Australian Pastoral Co composite program little question additionally influenced AA Co to embrace its personal composite program.
As historical past data, AA Co’s composite period flourished for round 15 years, earlier than round 2005, when the primary black F1 Wagyu x composite calves began to seems in northern firm breeding paddocks, as the ultimate ‘Wagyu period’ began to took maintain.
Whereas AA Co’s genetic ‘signature’ is now squarely aligned with its Wagyu breeding, feeding and advertising and marketing applications, composite breeders with no Wagyu genetic content material proceed to play a robust half in a few of the firm’s breeding operations to this present day.
The composite breeder gives a superb constructing block for AA Co’s F1 Wagyu applications, delivering a basis of fine consuming high quality efficiency on which to overlay some Wagyu marbling.
‘Directed evolution’
Pondering the corporate’s future path, the corporate’s one hundred and seventy fifth anniversary booklet revealed again in 1999 stated by way of genetic choice, ‘directed evolution’ and biotechnology, AA Co’s beef manufacturing effectivity and high quality had been elevated – and the long run held nice expectation and pleasure on this space for the corporate.
With the introduction of superior genetics, AA Co had the potential to provide “ten steaks out of ten” which are good to eat and food-safe, the 175th anniversary booklet stated.
“This beef shall be produced from cattle which have the genetics to be doubtlessly the most effective within the tropical world. Senior managers could have the tough process of selecting which expertise to undertake.
The complete potential of genetics advances is but to be seen,” it stated.
