Australian Lowlines are essentially 'miniature' Angus cattle, the by-product of a 30 year research project conducted by the New South Wales State Department of Agriculture at its Agricultural Research Centre located at Trangie, NSW. The first phase of the project, from 1963 to 1973, looked at using selection procedures based on genetic principles and measured performance. Funded by the then Australian Cattle and Beef Research Committee, the project sought to demonstrate, from within a stud herd, the application of selection procedures based on sound genetic principles and to isolate superior genetic material and to make this available to the Australian beef industry. The Trangie Stud's
Angus herd was established to provide high quality Aberdeen-Angus cattle
for New South Wales beef producers. The original foundation stock was
imported from James D. McGregor's Glencarnock stud in Canada in 1929.
Subsequently, more animals were obtained from Canada, as well as
from the USA, Scotland and a number of leading NSW Angus studs.
In all, Trangie acquired approximately 12 bulls and 30
cows/heifers during the 45-year period from 1929 to 1964. The herd then
remained closed for the next 30 years. It is from within this herd that
the Lowlines were derived. For the first seven
years of the project, until 1970, replacement stock were selected at
yearling ages, on a combination of their conformation score and their
corrected, weight. The
selection process was then modified, from 1971 to 1973, whereby some of
the replacements were selected by a panel of stud breeders using visual
appraisal while the others continued to be selected by the same method
used for the seven years previous.
When it became
apparent that both groups were selecting similar replacement animals,
i.e., those exhibiting the best combination of live weight gain and
conformation score, it was decided to look at the implications and
consequences of selecting for growth rate and what this could mean in
terms of herd productivity and profitability overall. Thus, the second
phase of the research project was established.
Phase 2 involved
the establishment of three closed lines, a high, low and a control line
in order to create a rapid divergence in growth rate between the two
extremes. In this manner, it was expected that the differences between
the Low and High lines achieved over a 15-year period would equate to a
30-40 year program of breeding in one direction only. In 1974, 50 head
were randomly selected from the Trangie herd of 220 performance recorded
cows. The remaining animals were distributed evenly into either the High
or the Low lines based on their individual growth performance at
yearling age. While all Control
line replacements were randomly selected, the High and Low lines
replacements were chosen based on their growth rate from birth to
yearling age, adjusted to take account of the age of their dams.
For the first 8 years, until 1982, the High and Low line herds
were maintained at approximately 85 head of females and 5 sires were
used each year. During the period 1983-85, all potential breeding
females were retained in order to create satellite herds at Glen Innes
(in NSW) and Hamilton, in Victoria.
On 30 October 1993,
the New South Wales Department of Agriculture conducted a Complete
Dispersal Sale. Some 22 bulls, 44 cows, 52 heifers and 29 Low Line
calves were sold. These animals, together with those obtained from
Trangie earlier, formed the basis of the today's Lowline herd.
As a result of
their breeding and the selection process followed, Lowlines are, on
average, between 100 and 110 cms tall at the hip. Smaller and larger
animals currently exist within the herd and the Australian Lowline
Cattle Association, formed in 1992, has yet to determine a definitive
height standard for the breed. Like their Angus
forebears, Lowlines are black and naturally polled. Like other Angus,
Lowlines potentially carry the red gene, however, no red Lowlines have
yet been recorded. (Trangie
actually bred first registered red Angus in Australia).
Being smaller-framed the Lowline's feed requirements are less
than those of larger sized cattle, although it is interesting to note
that during feed efficiency trials, at Trangie, on all three selection
lines, some animals were found to be up to 100% more efficient than
others in the same line. Similarly, at the Hamilton trials in Victoria,
the Low Line animals were shown not to require supplementary
Winter-feeding, unlike the Control and High Line animals in the same
trial. During the course
of the Hamilton trials, which compared the three selection lines at a
range of stocking rates per hectare, it was observed that the
productivity of the Low line cows was still rising when compared to the
High line animals at the same stocking (2 per hectare) rate.
Just as all
Lowlines share a diminutive size, as a result of the Trangie research
experiment, they also carry the prime beef qualities, and potential, of
their ancestors. In the 1940-50's,
the breeding policy of the Trangie stud was to produce early maturing
animals with good fleshing qualities and which demonstrated an economy
in the utilization of feed - traits that persist within a number of
animals within the Lowline breed. Because Lowlines
(and High-lines) were selected on the basis of a single trait, namely
their rate of growth to yearling age, vis-à-vis their group, the degree
of variability between animals in relation to other criteria increased.
As a result, it is difficult to categorize animals as a homogenous type.
This 'variability' is one of the main advantages of the breed.
While no two
Lowlines are identical, there is sufficient variation within the Lowline
gene pool to enable breeders to develop the type of animal they want.
While some breeders are attracted to the idea of producing small, easily
managed animals that are ideal for small areas, other breeders are more
intent on maximizing the production of beef per hectare.
Lowlines are perhaps the only breed of cattle in the world today
that can fulfill both of these objectives.
Lowlines are also
the direct descendants of prize-winning Angus bloodlines. Although
Trangie discontinued showing its animals in the 1960's, because of the
need for uniformity in its feeding regimes, it had had considerable
success in the show ring up until this time.
There is no doubt
that the Australian Lowline breed will develop further,
