npHE Fifth Random Sample Egg Laying Test differs from the four previous ones in that the names of entrants are published with the results.
This procedure was adopted after a meeting of the Joint Poultry Industry Improvement Committee in April, 1961.
The Committee is a body made up of representatives from all organised sections of the poultry industry and one of its functions is to advise on policy in the random sample test.

WITH the ever-increasing spread of salt in certain poorly-drained soils in Western Australia, any plant which tends to restrict salt encroachment is of considerable economic importance.
In the genus Eucalyptus there are a few trees which will withstand a certain degree of soil salinity.

Journal of the Department of Agriculture, Western Australia, Series 4
A broiler trial to compare the performances of three special meat strains and a group of first cross cockerels was conducted at the Poultry Research Station, Wembley, in 1962.
Although there was little difference in profit there are several factors in favour of the special meat strain birds for broiler production.

Grow More Wool, W L. Mcgarry, R. J. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 4
THE amount of wool that each sheep grows is determined by many things, including the amount and quality of pasture available or how the sheep are fed, the stocking rate, the general health and thrift of the sheep and other management considerations such as cropping and the time of lambing.

Select On Fleece Weight And Cull The Low Producers, W L. Mcgarry
Journal of the Department of Agriculture, Western Australia, Series 4
EFFICIENT calling of maiden ewes before they join the breeding flock is an essential part of any policy of flock improvement.
Removal of the low wool producers should be one of the first considerations when culling the flock.

Journal of the Department of Agriculture, Western Australia, Series 4
THE time is approaching on most dairy farms when a decision has to be made on which of the year's crop of heifers are to be retained.
Replacements are needed not only to keep up herd numbers, but also to increase the average production.
This is herd improvement—surely the aim of all dairy farmers.

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.

HOW many pig raisers have even a rough idea of their margin of profit from pigs?
Even in the present time of low returns, the answer is obviously "far too few".

THE figures in the table below give the progressive laying report to May 27, 1962, after 22 weeks of production.
The entries are ranked in order of profit, but undue emphasis should not be placed on the results of this progress report, which refers only to one uncompleted test.

THIS species was described by Mueller in February, 1880, from a fragment with buds and flowers without fruits, collected by George Maxwell in South-Western Australia, without any locality.
It remained imperfectly known until a few years ago when a specimen was collected, again without precise locality, but somewhere between Esperance and Eyre,

THE response to the Department's appeal for identical twin calves has been gratifying, and so far this year five sets have been located and collected.
In view of the rare occurrence of identical twinning, this indicates excellent co-operation from dairy farmers.

Flock owners' thoughts are now turning towards culling.
Culling should remove the worst sheep and keep the best to fill the bales and breed replacements.
A valuable aid to this annual task is Culling by Fleece Weight during shearing

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.
