Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall
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.

Journal of the Department of Agriculture, Western Australia, Series 4
SHEEP, pastures and labour are the major resources of the sheep enterprise but their productivity is greatly affected by the timing of operations associated with them.
This article discusses how the lambing time can be chosen to get maximum use from each resource.

FIRST THREE-YEAR-AVERAGE REPORT FOR THE WEST AUSTRALIAN RANDOM SAMPLE LAYING TEST COVERING THE 4th, 5th AND 6th TESTS
Despite every effort made to provide all entries in individual tests with a uniform environment it is still possible for a particular entry's performance not to be a true indication of its inherent ability.
Random Sample Test results should therefore be viewed on a long term, annual, consecutive basis. If the yearly results for a given hatchery are grouped together and averaged over a period of several years irregularities in performance due to factors other than genetic worth are minimised and a …

TO help improve the quality of laying stock for poultry farmers in Western Australia the Poultry Branch of the Department of Agriculture conducts annual random sample egg laying tests.
The tests reveal good and bad points in the laying strains available, and their results are a valuable guide to breeders.
Most of the chickens sold in Western Australia are now bred by hatcherymen who participate in the Random Sample Tests.

AS part of the poultry improvement plan for Western Australia, the Department of Agriculture inaugurated a random sample laying test for commercial grade chickens at the Poultry Research Station, Herdsman Lake, in 1957.
The results of the first test appeared in the May-June, 1959 issue of the Journal of Agriculture and those of the second test in the June, 1960 issue.

Selecting A Herd Sire, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
THERE is now ample evidence that most of the differences in production between herds are determined by feeding and management, with differences in genetic merit playing a relatively minor role.
It seems that the quickest way to increase production is by improved feeding, whilst in some herds much production is being lost by faulty milking techniques.
