In the study, three separate herds were established: one of animals with a high rate of growth in their first year, one with animals that had shown low growth, and one randomly selected as a control group. These were called the High Line, the Low Line and the Control Line respectively. The Low Line herd started with 85 cows and some young bulls, and was closed to additions of other stock from 1974; it eventually numbered more than 400. To exclude possible effects of climate from the study, some stock was reared at

calve easily and provide plenty of milk to their young.
Compared to larger cattle, the Lowline does less damage to pasture land, and does not need such high or strong fencing.
Use
The Australian Lowline is reared for beef. The meat is well
marbled and tasty; carcass yield is high.
