Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia

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

THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.

The profit from selling beef must be compared with that from selling excess calves off their mothers.

Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.

Linseed Within The Clover Ley Farming System, Department Of Agriculture, Western Australia

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

LINSEED was one of the first crops to be widely used as an alternative to cereals in the over-17 inch rainfall areas. It is now an established crop with a total 1969 production worth just under half a million dollars.

Linseed is currently worth nearly twice as much as wheat per bushel, wih its short term prospects still attractive.

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.

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

Rationing Standing Crops To Sheep, H E. Fels

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

This experiment was done at Merredin Research Station to develop and test a method of rationing standing crops to sheep, and also to find whether rationing would reduce the sheep's water consumption.

The experiment involved 60 sheep on 12 one-acre plots of drought affected Gamenya wheat.

Recommended Crop Varieties-1971/Vol11/Iss12, H M. Fisher

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

Cereal and linseed varieties recommended for 1971 should give the best returns to growers and benefit the industry in general, The main varieties are Gamenya, Bokal and Darkan wheats, Dampier and Beecher barleys, Swan oats and Kameniza linseed.

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.

Linseed : An Alternative Crop For The South Coast. 2. What Is The Future For Linseed?, R J. Doyle, R. J. Guyton

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

In a preceding article* we stated that the expansion of linseed in Western Australia was due primarily to the ability to sell on the export market at current ruling prices.

This is necessary because Australia's domestic needs are likely to be supplied in most years by Eastern States producers.

Urea Drilled With Seed Affects Germination And Yield, M G. Mason, A. Loutit, J. A. C. Smith, D. Highman, P. Stallwood

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

Trials in 1968 at Burracoppin and York again showed it is safer to topdress urea just before seeding than to drill a mixture of seed and urea.

At all but the lowest urea rates, urea drilled with the seed reduced the number of plants emerging and surviving, and reduced final wheat yields.

Lucerne Establishment In High Rainfall Dairying Districts, R Sprivulis

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

LUCERNE is one of the oldest of perennial forage plants. It originated in the Middle East and because it flourishes under a wide range of climatic and soil conditions it is being grown in many parts of the world.

Lucerne was introduced to Australia in the early years of British settlement. The original introductions proved suitable for the alluvial flats of the Hunter and Peel River valleys of N.S.W.

Lucerne is basically a summer growing legume with or without winter dormancy.

Rapeseed Production In Western Australia, M L. Poole

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

RAPESEED production began in Western Australia in 1968 when a few acres were grown. In 1969, about 20 growers ptanted small acreages for about 80 tons of seed. In 1970, up to 20,000 acres will be grown, and a total of 40,000 acres seems possible within the next few years.

Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell

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

FARM experience and the results of five years intensive research have shown copper deficiency to be widespread in the south-eastern wheatbelt.

On many areas of the south-eastern wheatbelt, copper deficiency is likely to restrict wheat yields.

Growing Barley For Grain In Western Australia : Varieties And Production Methods, H M. Fisher

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

BARLEY is an adaptable crop which can be grown successfully throughout the cereal areas of Western Australia. It is more suited to the wetter areas than wheat and tolerates the drier, shorter season of the eastern cereal districts better than oats.

Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones

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

WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.

Prime Lamb Production In Western Australia : A Review Of The Development Of The Prime Lamb Industry In Western Australia, R J. Suiter

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

PRIME LAMB production in Western Australia has evolved into an industry based almost entirely on the local market.

This has not always been the case. In the 1930-40 era a substantial proportion of the State's prime lamb production was exported to the United Kingdom.

During this era the industry was equally dependent on exports and local market.

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

Hydatid Disease In Western Australia, G C De Chaneet

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

BECAUSE hydatid disease is a disease of humans as well as animals, every dog owner should be aware of the conditions that perpetuate hydatids and the methods of control.

The incidence of hydatids in Western Australia in the past has not been high.

However, the increase in sheep numbers over recent years, together with the intensification of farming methods, may lead to a rise in incidence unless stock owners, particularly sheep farmers, take steps to control the disease.

The New Stock Diseases Regulations : A Summary Of Major Regulations Under The New Stock Diseases (Regulations) Act, M R. Gardiner

Causes Of Low Lambing Percentages, Department Of Agriculture, Western Australia

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

West Australian Merino flocks average about 70 per cent, lambs marked each year. Reasons for this low percentage are that as many as 30 per cent, of ewes do not lamb, twinning rates are low and from 10 to 25 per cent, of lambs born die.

Among the research projects by the Department of Agriculture's Sheep and Wool Branch have been a number directed at the various stages of reproduction in the ewe. These have given some important leads on the causes of low lambing percentages.

If you have marked less than 60 per cent, lambs in the past several …

SUBTERRANEAN CLOVER INOCULATION EXPERIMENTS Badgingarra and Newdegate Comparisons between Rhizobium trifolii strain WU290 and possible replacement strains were continued. The work was conducted for the following reasons 1. The need for information on "back-up" strains particularly since the inoculant manufacturers had experienced difficulty in producing high-count peat cultures of WU290. 2. Strain CC2480a had proved very satisfactory in the Eastern States. Although it did not show up to advantage under our conditions in 1968,further testing was indicated. 3. The need for information on inoculation needs on old land.
