The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 4
THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.
In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.
The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.
Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler
Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler
Journal of the Department of Agriculture, Western Australia, Series 4
The first article in this series described the worms which commonly infest sheep in Western Australia and the symptoms caused by heavy infestations.
This article outlines the effects of seasonal changes on worm burdens in sheep.
AS a basis for planning a worm control programme it is essential to have information on the seasonal changes in worm burdens and on the factors which control these.
In this article, the more important of these are considered.
A Measure Of Clover Infertility In Ewes, N Davenport
A Measure Of Clover Infertility In Ewes, N Davenport
Journal of the Department of Agriculture, Western Australia, Series 4
SERIOUS impairment of the breeding ability of ewes grazed for prolonged periods on growing pastures containing dominant subterranean clover has been experienced in Western Australia for many years.
The first widespread recognition of the problem coincided with the upsurge of improved pasture establishment based on the Dwalganup variety of subterranean clover in the higher rainfall sections of the wheatbelt and adjacent sheep raising areas to the west and south.

THE weather had been remarkably pleasant, with an odd shower of rain followed by several warm days.
Just the weather for blowfly troubles, so the owner decided it was time he crutched his breeding flock of 500 ewes.
But as the mob approached the yards trouble was coming
Special Field Days For Merino Breeders, Department Of Agriculture, Western Australia
Special Field Days For Merino Breeders, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
More than 200 Merino stud breeders attended special stud breeding and fertility field days arranged for them by the Department of Agriculture recently.
Breeders attending represented some 40 per cent of the State's Merino studs.
Worms In Sheep. 3. Control Of Worms By Drenching, R W. Butler
Worms In Sheep. 3. Control Of Worms By Drenching, R W. Butler
Journal of the Department of Agriculture, Western Australia, Series 4
DRENCHING for worm control must be carefully timed in relation to the effect of climatic conditions on the development and survival of worm larvae on the pastures, and the seasonal variation in worm burdens carried by sheep.
