The Lowline breed trials began in 1974 to evaluate selection for growth rate on herd profitability.

The aim was to establish whether large or small animals were more efficient converters of grass into meat. This trial lasted for 19 years.
The Trangie staff chose one herd selected for high yearling growth rates and another selected for low yearling growth rates, with a randomly selected control group. The dubbed the herds Highline, Lowline and Control Line. Satellite herds were established at Glen Innes in the northern tablelands of NSW and at Hamilton in the Western Districts of Victoria to enable climate to be taken into account.
All were evaluated on weight gain, feed intake, reproductive performance, milk production, carcass yield and quality and structural soundness. The protein conversion performances of the Highline and the Lowline cattle were monitored and recorded on an individual basis. The lines continued to grow apart with the selection process and recorded on an individual basis.
After 15 years, the Lowline had stabilised at 30% smaller than the Highline cattle. The bulls matured at about 43 inches, and the cows at about 39 inches or less, against 59 inches for standard Angus bulls, and close to the same height for standard Angus cows.
Interested cattlemen bought Lowline cattle from the dispersal sales from the termination of the trials at Trangie and Glen Innes, and in 1992 created the Australian Lowline Cattle Association. Although the aim was not to create a new breed, the Lowline has proved successful and interest in the breed has increased ever since.
Australian Lowlines are of champion stock with an Australian history dating back to 1929, and beyond that in Canada, the United States, England and Scotland. They are docile, and well conformed. They offer small holders and those farmers with limited acreage available from their other activities the option of keeping docile cattle of high quality. The Scots who first developed black cattle would be as proud of the Lowlines as of any of their giant cousins. They made their first appearance at the Brisbane Royal National in 1994, and subsequently at the Sydney Royal Show in 1995, and Melbourne and Canberra Royals in 1996. They are now regular exhibits at agricultural shows around Australia.
