Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin Jan 1990

Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin

Bulletins 4000 -

Photosensitization is the term used to describe inflammation of the skin (usually unpigmented) caused by photodynamic compounds, circulating in blood stream, becoming bound to dermal cells and fluorescing when the animal is exposed to ultraviolet light (290-400 nm).

Photosensitization usually occurs when an animal eats certain plants that contain photodynamic compounds. These compounds can be deposited unchanged in the skin after ingestion, the normal liver being incapable of excreting the native fluorescent compound. This is termed type 1 photosensitization and the compounds involved are naphthodianthrone derivatives. Photodynamic compounds can also be produced through aberrant metabolism by the liver due to …

Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry Jan 1990

Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry

Bulletins 4000 -

An inadequate distribution of watering points in our pastoral lands, particularly in the saltbush/bluebush pasture, has caused localisized land degradation close to waters and reduced animal productivity (particularly in stressful times). From experimentation and observation, some generalised recommendations for water supply distribution in pastoral areas can be made.
