Lupin Stubbles : Getting The Best With Weaner Sheep, Keith Croker, Colin Mcdonald, Jeremy Allen

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

Sweet lupins are now grown on about a million hectares in Western Australia each year. If half of the State's seven million weaners were grazed as recommended on half of the lupin stubbles, it could generate about $15 million from reduced supplementary feeding, greater wool production and other advantages. But correct management is important, particularly knowing when to take weaners out. Research by the Department over the last five years is now indicating how this should be done.

Phomopsis-Resistant Lupin Stubbles As Feed For Weaner Sheep, Colin Mcdonald, Keith Croker, Jeremy Allen

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

The breeding of sweet, narrow-leafed lupins with increased resistance to Phomopsis leptostromiformis, the fungus that causes lupinosis in sheep, is a breakthrough for the summer nutrition of weaner sheep. The new resistant varieties, Gungurru for the medium (325 to 450 mm) rainfall areas and Yorrel for low rainfall areas (less than 325 mm), were released by the Department of Agriculture in 1988.

This article discusses progress in a four-year project which is examining liveweight and wool production of weaners grazing Gungurru stubbles.

Lupinosis : A Disease Still With Us, Jeremy G. Allen, P. Mcr. Wood, K. P. Crocker, J. Hamblin

Current research on lupinosis continues to reveal what a complex problem it is, but the improved understanding should help to reduce losses.

Lupinosis And Rates Of Stocking Of Lupin Stubbles, K P. Croker, J. G. Allen, C. R. Lester, R. B. Guthrie

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

Lupin stubbles provide valuable summer sheep feed but under some conditions the fungus Phomopsis rossiana (for which lupins are the host plant) produces a toxin that causes lupinosis. Results from research at Badaingarra Research Station over the 1973-74 and 1974- 75 summers have shown that sheep liver damage associated with lupin stubble grazing is likely to be more severe at high than low stocking rates.

Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones

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

WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.
