Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
Today in Western Australia, sheep are run at slightly higher stocking rates, are achieving greater lambing percentages (up JO per cent) and higher wool cuts per animal ( up 0. 6 kg greasy) than in the 1960s. When all components of production are considered, the productivity of sheep fanns has increased by 2. 7 per cent per year over the past 35 years.
The challenge of the next decade is to achieve substantially greater rates of improvement than for past years if the sheep and wool industries are to maintain their significant place in Western Australian agriculture.

The judicious use of artificial insemination (Al) of ewes with frozen semen by ram breeders offers substantial gains for wool producers, but it promises even greater benefits if it can be used more widely within commercial breeding flocks.
In the Western Australian dairy industry, for example, genetic gains between 1971 and /986 are estimated to have been three times as great in herds bred by Al as in herds that were mated naturally.
