Benefits And Costs Of Saltland Pastures On Moderately Salt-Affected Land, Justin Hardy, Arjen Ryder

Resource management technical reports

Summary The analyses in this report show that there could be significant economic benefits to the state, regions and affected farm businesses from establishing improved saltland pasture systems on moderately salt-affected land. The report clearly describes the methods of analysis and the assumptions about prices, productivity and adoption levels. The price of grain has been used as the key factor controlling the economic value of the saltland grazing because grain is the alternative supplementary feed for sheep over the summer and autumn period. Therefore, where yield is below break-even on moderately salt-affected land, it has a higher economic value and …

Feed On Offer Photo Gallery : For Annual Pastures During The Green Period, Mandy (Catherine Amanda) Curnow, Lifetimewool (Australia)

Books & book chapters

Food on Offer, or FOO, is the amount of pasture available for sheep to eat. It is measured as dry matter per hectare, and then used to budget feed available and stocking rates for a given period.

FOO includes all green material above the ground and it is reported in kilograms of dry matter per hectare (kg DM/ha).

Bulletins 4000 -

This manual has been produced as a joint venture between the Wool and Meat Programs of Agriculture Western Australia. It is intended to provide current information on most animal production issues today. It has been modified from the current Woolpro and Prograze manuals distributed to farmers and is designed for use mainly by Agricultural Colleges and Secondary Schools teaching Agriculture. It should be used in conjunction with these manuals.

The Good Food Guide For Sheep : Feeding Sheep For Meat Production In The Areas Of Western Australia, Keith Croker, Peter Watt, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

The Good Food Guide for Sheep has been produced to provide Western Australian farmers with a concise compilation of current information on feeding sheep for meat production. Although there are already numerous publications about sheep nutrition,many of them relate to wool production, reproduction or drought feeding, or they concentrate on particular feeds or feeding systems.

This book contains information on a wide range of feeds and feeding methods. Just as there is no single ‘best’ sheep breed for meat production, there is no ultimate feed regime for sheep for growth.

How Sustainable Is Grazing Sheep On Annual Pastures In The Woolbelt?, Don Mcfarlane, Richard George

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

Low wool prices have reduced the profitability of producing wool from clover-based annual pastures in the south-western woo/belt. The heavy reliance on one commodity is economically unsustainable for many farmers. But we should also consider how ecologically sustainable the practice is.

Shallow-rooted annual pastures contribute to widespread salinity in the area, annual legumes are acidifying the soils and making them water repellent, and bare, detached soils from heavy grazing cause sheet and rill erosion during autumn storms. In addition, stock are degrading remnant vegetation and destroying the soil's structure.

To counteract this degradation, the woo/belt needs more perennial pastures and …

Quality Wool Production At Lower Cost, Peter Metcalfe

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

Low wool prices are forcing farmers to reduce their sheep management costs but, fortunately, cost cutting is not resulting in lower wool production, poorer wool quality or lessened sheep care on the best wool growing properties.

Studies On Times Of Lambing In Ewes Grazing Subterranean Clover Based Pastures In Relation To Stocking Rates In South-Western Australia, H Lloyd Davies

Technical Bulletins

The investigation is reported in six parts: effect on ewe liveweight and fertility, lamb losses, effect on lamb growth and subsequent growth after weaning, wool production, pasture production and composition, and conclusions and practical implications. The results show that in the absence of supplementary feeding the physiological requirements of ewes in late pregnancy are better met by spring rather than autumn lambing.

Doublegee Control In Pasture : What Is It Worth, D J. Gilbey, R. J. Lightfoot

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

A recent study showed that the cost of spraying to control a heavy doublegee infestation can be recovered in the first year of the spraying.

Super And Stocking Rates At Kojonup After 10 Years, J W. Bowden, B. Scurr, R. Glencross, K. Longbottom

Reproductive Wastage Among Merino Ewe Flocks. 2. Non-Clover Areas, T Marshall, B. R. Beetson, R. J. Lightfoot, G. R. Mcmullen

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

This research sought to define the reasons for low fertility among Merino ewes in Western Australia.

This first article looks at wastage in Non-Clover areas

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

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.

Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce

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

IN the past, chemical treatments for the control of weeds in pastures have been costly and severe on pasture, and have had to be repeated over a number of years. The method outlined in this article overcomes nearly all these disadvantages.

Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick

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

In its virgin state the area carried a forest association of red-gum and jarrah, and the soils are typical of large areas in the south-west of Western Australia.

These gravelly soils have a high requirement for phosphate during their first years under pasture, and this trial was designed to investigate the relationship between rate of phosphate, stocking rate and pasture production over a number of seasons.

Heavy Rate Set Stocking : Esperance Downs Research Station, R J. Doyle

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

Set Stocking Has A Place In Soil Conservation Farming, J E. Watson

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

Set stocking of sheep at increased stocking rates is rapidly becoming popular with farmers in the agricultural areas of Western Australia.

But will set stocking increase soil erosion hazards? It should do just the reverse, according to Soil Conservation Adviser J. E. Watson, B.Sc, who claims that set stocking has a place in soil conservation farming.
