Reproductive Wastage In Sheep In Non-Clover Areas, C. H. Trotman
Reproductive Wastage In Sheep In Non-Clover Areas, C. H. Trotman
Journal of the Department of Agriculture, Western Australia, Series 4
A Research Round-up report in the June, 1972, issue of the Journal of Agriculture discussed the reproductive performance of sheep in Western Australia and indicated that more than 20 per cent, of mated ewes fail to lamb.
The report presented the first year's results from sheep grazing clover areas.
This report presents results from the nonclover sections of the investigations
Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.
It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
A recent field experiment on established pastures at Esperance Downs Research Station has demonstrated a relationship between superphosphate application, pasture oestrogens and oestrogenic response in sheep.
Results of the experiment indicate that on phosphate deficient soils carrying oestrogenic clovers, the levels of oestrogenic materials in the pasture are increased if superphosphate applications are below those recommended for healthy pasture growth.
Damage Caused By Hormone-Like Herbicides, G R W Meadly
Damage Caused By Hormone-Like Herbicides, G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
THE discovery of the selective action of herbicides such as 2,4-D and MCPA resulted in a rapid expansion in the use of these chemicals for agricultural purposes, particularly for the control of weeds in cereal crops.
Clover Disease Of Sheep In Western Australia, A B. Beck, M. R. Gardiner
Clover Disease Of Sheep In Western Australia, A B. Beck, M. R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
DURING the past five years there has been a marked increase in the incidence of breeding abnormalities of sheep associated with the grazing of subterranean clover pastures.
This complex of diseases first became a major problem in Western Australia in the years following 1940 and eventually became known as "clover disease".
Fatique In Caged Layers, P Smetana
Fatique In Caged Layers, P Smetana
Journal of the Department of Agriculture, Western Australia, Series 4
Pullets found immobilised on the floors of their laying cages may only be suffering from the easily-treated "cage layer fatigue" and should be checked for this before being disposed of as affected with the incurable fowl paralysis.
The Control Of Bitter Pit In Apples, Frank Melville, S. E. Hardisty, N. S. Shorter
The Control Of Bitter Pit In Apples, Frank Melville, S. E. Hardisty, N. S. Shorter
Journal of the Department of Agriculture, Western Australia, Series 4
Bitter pit is a physiological disorder of apples which causes considerable wastage of otherwise sound fruit .
It is a problem of world-wide occurrence and in Western Australia growing conditions appear particularly favourable for its development.
In recent years a practical means of control by calcium sprays has been developed.
Modern Methods Boost Apple Production In A South-West Orchard, N H. Shorter
Modern Methods Boost Apple Production In A South-West Orchard, N H. Shorter
Journal of the Department of Agriculture, Western Australia, Series 4
A WELL-KNOWN South-West apple orchard with an impressive cropping record is owned by W. F. & E. M. Dilley and Sons, of Upper Capel, near Donnybrook.
Trees in this orchard have been producing consistently heavy crops for many years and, furthermore, yields have increased steadily over a 10-year period.
Broiler Research. 1. Meat Strains For Broiler Production, P Smetana
Broiler Research. 1. Meat Strains For Broiler Production, P Smetana
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.
Autumn V Spring Shearing, W L. Mcgarry, I. K. Stott
Autumn V Spring Shearing, W L. Mcgarry, I. K. Stott
Journal of the Department of Agriculture, Western Australia, Series 4
IN the agricultural areas of this State it is customary to shear in the late winter or spring, usually some time between July and September.
In an experiment conducted at Muresk Agricultural College during the past two years it has been shown that shearing in autumn (March) has resulted in more wool being produced with higher returns than when shearing at the conventional time.
