Phosphate Applications Affect The Coumestrol Level Of Medics, T Marshall, R. J. Parkin

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

Western Australia has a million acres of medics including various cultivars of barrel medic, Medicago truncatula, and strand medic, M. littoralis. Both species contain coumestrol, a chemical thought to have caused delayed conception and reduced twinning rates among grazing ewes in New Zealand.

No infertility has been reported among ewes grazing medic pastures in Western Australia, but coumestrol levels in both species have often been high enough to suggest the possibility of oestrogenic responses among sheep grazing them.

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.

Surplus Cereal Crops For Sheep Feed, H E. Fels

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

SINCE the introduction of wheat quotas many farmers have considered feeding unsaleable grain to sheep.

The three alternative methods of feeding this grain to sheep are

• as standing crops

• as grain supplements, fed in the paddock

• as grain plus hay, in a feedlot.

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley

Masters Theses & Specialist Projects

The effects of chemical additives on the fermentation pattern and subsequent feeding value of corn silage was investigated over a two year period. Corn plants harvested in August 1967 (Experiment I) were ensiled with no additive, 3.50 per cent area, or urea-mineral mix supplying an equal amount of urea. Those harvested in August 1968 (Experiment II) were ensiled with no additive, 0.50 per cent urea, or 0.75 per cent urea. The nutritive value of these silages was evaluated chemically and by lactation trials.

:he addition of urea alone, or in combination with minerals elevated the initial pH and buffered against …

Crop Rationing : A Useful Drought Feeding Technique, H E. Fels

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

A TRIAL carried out during the 1969 drought demonstrated that rationing standing crop is a practical method of feeding it to sheep when feed is scarce.

Rationing will be mainly a drought feeding technique for that part of the crop which will definitely be used as sheep feed. Crop that may or may not be needed for sheep would normally be harvested and the grain kept as a contingency allowance.

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.

The Protection Of Primary Production : The Role Of The Agriculture Protection Board Of Western Australia, A R. Tomlinson

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

THE main function of the Agriculture Protection Board of W.A. is, as its name implies, "protection", and, in this case, it is the State's primary production which is being protected from pest animals, birds and weeds.

In general, the Board's activities are centred on the prevention, destruction or management of animals and plants which are troublesome to agricultural or pastoral production, or are capable of being troublesome.

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.

Control Of Clover Infertility In Sheep, H G. Neil, H. E. Fels, C. M. Francis

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

A summary of practices recommended for the control of infertility caused by subterranean clover in West Australian sheep.

PROLONGED grazing of green subterranean clover pastures often reduces ewe fertility. In more extreme cases, obvious signs of clover disease occur.

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.

Deferred Grazing Improves Soft Spinifex Association, H Suijdendorp

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

THE Pastoral region in Western Australia where Triodia pungens (soft spinifex) makes up most of the vegetation, covers an area of about 17,000 square miles in the Forrest and De Grey pastoral areas.

On the deeper granitic sands in much of the region, plant associations revert to a pure stand of soft spinifex after about five or six years' grazing. It is common practice to burn at this stage, to encourage the re-establishment of other species and the production of palatable spinifex regrowth.

Higher Stocking Rates For Cattle On Irrigated Pasture : A Report From Wokalup Research Station, Maurice C. Cullity

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

The possibility that higher cattle stocking rates than those commonly used could be economical was suggested by the results of a stocking rate trial at Wokalup Research Station

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …

Osteology And Myology Of Phrynosoma P. Platyrhinos Girard And Phrynosoma D. Hernandesi Girard, Richard L. Jenkins, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

This study confirms the work of Etheridge (1964) in suggesting the peculiarity of the genus Phrynosoma within the family Iguanidae. The anterior osteology and myology of Phrynosoma platyrhinos platyrhinos Girard and Phrynosoma douglassi hernandesi Girard indicate Phrynosoma to be highly specialized and to differ significantlv from the Iguanid structure as portrayed by Oelrich (1956), Robison and Tanner (1962), and Avery and Tanner (1964). They also differ because of: ( 1 ) absence of lacrimal and postfrontal bones; (2) occurrence of occipital (also mandibular and temporal) spines; (3) posterodorsal shift of the skull elements; (4) divided nature of the M. sternohyoideus, …
