Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin Jun 1979

Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin

Bulletins - 3000 - 3999

This article deals with those native, naturalized and cultivated plants, which by virtue of contained cyanogenetic glycosides, are known to be poisonous or potentially poisonous to livestock in Western Australia.

Cyanogenetic glycosides are chemical compounds which contain a cyanogen (cyanide) radical combined with a sugar molecule. The sugar moiety may differ in glycosides obtained from different plants, and as a consequence glycosides from different plants, containing different sugar moieties, may be given different names.

When a cyanogenetic glycoside is broken down by enzyme action, through injury to the plant or by microbial action in the digestive system of the animal, …


Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson Jan 1976

Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson

Bulletins - 3000 - 3999

Vitamin A is one of the essential vitamins for animal health. Grazing animals obtain their vitamin A requirements mostly from the carotene in green feed. This carotene is converted to Vitamin A in the intestinal wall and is passed to the liver and to a less extent the kidneys for storage. Some carotene also passes direct to the liver where it is stored before it is converted to vitamin A.

When dry pastures, hay and grains (except maize) are low in carotene content this ability of the animals to store vitamin A means that they usually have enough when there …


Bulletin 3955 - The Sheep Skin Industry In W.A., H. E. Fels Jan 1976

Bulletin 3955 - The Sheep Skin Industry In W.A., H. E. Fels

Bulletins - 3000 - 3999

The sheep skin industry is larger than most people realise. Its importance is shown by F.O.B. values of sheep skin exports from Australia in 1972/73, compared with sheep meats, wheat and iron ore,

F.O.B, values of exports - Australia, 1972/73

Sheep skins, with and without wool on $110 million

Mutton and lamb Exports $119 million

Wheat $274 million

Iron ore and concentrates $439 million


Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson Oct 1968

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 …
