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 Jan 1970

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.


Crop Rationing : A Useful Drought Feeding Technique, H E. Fels Jan 1970

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.

Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell May 1969

Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative index to digestible nutrients was established for Russian wildrye, crested wheatgrass, and intermediate wheatgrass seeded on foothill areas of Utah. The nutritive values of these grasses were compared by the lignin ratio method, the chlorophyllan ratio method, and the in vivo rumen bag process.

Average digestion coefficients computed by the lignin ratio method for dry matter, ether extract, cellulose, and gross energy were highest for intermediate wheatgrass. Protein was more digestible for Russian wildrye. Digestible energy was adequate in all species to meet requirements for late lactation.

Results from the chlorophyllan ratio method were excessively high and were …


Quantitative Evaluation Of Saponin Content In Du Puits Alfalfa Foliage (Medicago Sativa L.) With Trichoderma, Wang Li-Chun May 1969

Quantitative Evaluation Of Saponin Content In Du Puits Alfalfa Foliage (Medicago Sativa L.) With Trichoderma, Wang Li-Chun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Selections in Du Puits alfalfa (Medicago sativa L. ) were evaluated for saponin content. The data obtained from the Trichoderma bioassay were converted to saponin values by regressions and standard curves. It was necessary to adjust the concentration of alfalfa extract in the bioassay so that the saponin content in alfalfa was estimated in that portion of the curve showing a marked response to saponin. A different regression was established for each group of low and high saponin plants of Du Puits alfalfa. The standard curve prepared with extract of Du Puits alfalfa used on the basis of its …

West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia

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

FARMING the light lands of the West Midland area would be impossible without fertilisers.

Most light land areas are inherently very low in phosphate and also require nitrogen.

The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.


Fertiliser Responses With Newly Planted Apple Trees, N H. Shorter Jan 1968

Fertiliser Responses With Newly Planted Apple Trees, N H. Shorter

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

Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason Jan 1968

Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason

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

Generally similar results may be expected from all the sources of nitrogen available for cereal growing.

The unit nitrogen price and the convenience of use of each fertiliser in the particular situation should be taken into account in deciding which fertiliser to use.

THE first point to consider when deciding which nitrogen fertiliser to use for wheat growing is the effectiveness of the nitrogen source in increasing crop yield. Second, the cost per unit of nitrogen must be considered.

The convenience of using a particular source in a particular situation is also important and greater convenience may offset some cost …
