Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd

Bulletins 4000 -

Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the …

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts

Bulletins 4000 -

Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).

A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.

Ill thrift and poor growth of weaner …

Returns To Research And Development Investment Of Department Of Agriculture And Food Western Australia : Benefit Cost Analysis 2005-2006, Nazrul Islam, Francis Bright, Peter Coyle, Peter Eckersley, Louise Evans, Joseph Gaffy, Allan Herbert, Ross Kingwell, Emma Kopke, Peter Tozer

Programs of the Department of Agriculture and Food Western Australia apply benefit-cost analysis to assist in the allocation of funds to those areas likely to make the largest contribution to the rural economy and thus to achieve the Department outcome of increased market competitiveness and profitability. To learn lessons from the completed projects the Programs also use ex post analyses. Information collected in the course of the ex post analyses can usefully improve the assessment of proposed projects.

Returns To Research And Development Investment Of The Department Of Agriculture And Food Western Australia : Benefit Cost Analysis, 2006-2007, Peter Coyle, Editor, Roslyn Blanchard, Francis Bright, Paul Mattingley, Manju Radhakrishnan

Bulletins 4000 -

Strategic decision making is enhanced by the consideration of benefit cost analyses of many projects. Each year a selection of projects is evaluated to assist in the determination of the most appropriate allocation of funds. This is only one of the methods that are employed by the Department’s Executive to increase market competitiveness and profitability in agriculture and the pastoral industries. This report includes both ex post and ex ante analyses, as they are complementary processes.

The annual species subterranean clover (Trifolium subterraneum L.) is the most important pasture legume in Western Australia. In addition to providing nutrious feed for livestock, it is an important source of nitrogen for non-leguminous species in pastures for the State's ceral crops.
