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 …

Multi-Timer For Milking Studies, G W R Scott Jan 1964

Multi-Timer For Milking Studies, G W R Scott

Journal of the Department of Agriculture, Western Australia, Series 4

Recent research into milking machine operation has proved that the belief of old-time hand-milkers that fast milking was good milking was soundly based.

In current practice the emphasis is on convenient shed and yard design and systematic routine in handling the cows. This permits a high throughput of cows and a high output of milk per labour unit.

The multi-timer designed and built by Mr. G. W. R. Scott and described in this article will prove most valuable for pinpointing where time is lost.
