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.

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

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

The calendar contained in this article has been drawn up by officers of the Wheat and Sheep Division as a guide to farmers who plan to adopt July-August lambing.

The article also summarises the advantages and complications of later lambing (as opposed to the conventional autumn lambing) and discusses farm management programmes to deal with the problems in various districts.

Piglet Anaemia : An Iron Deficiency Disease, F C. Wilkinson

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

PIGLETS are born usually with only about 40 mg. of iron in their bodies and the sow's milk only supplies about 1 mg. of the 7 mg. needed each day by the piglets.

This means that if the piglets do not get additional iron, the body stores soon become depleted and anaemia occurs at about one to three weeks of age.

Acetonaemia In Dairy Cows, F C. Wilkinson

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

ACETONAEMIA is a common disease of newly calved cows in the dairying districts of Western Australia.

Affected cows practically dry off and lose a lot of body condition; these are the main causes of loss to the owners.

Weaning And Weaner Management, R J. Lightfoot

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

MOST of Western Australia's Merino flock owners wean their lambs in the months of August, September and October.

Too often this is done indiscriminately to fit in with other operations, or lambs are left on their mothers for long: periods until the ewes are remated.

Can Worms Be Controlled By Correct Feeding?, Laurence C. Snook

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

THE extensive losses which result from the ravages of internal parasites are a matter of serious concern.

Livestock owners realise this all too well and welcome advice concerning control measures which can be adopted. Unfortunately, it is not possible to give clear cut advice on the subject.

Much publicity is given to the use of drugs which will expel the worms. Various systems of strategic drenching have been developed.

It is well to remember, however, that drenching is only one of many methods which can be used to control worm infestation.

In this talk attention will be concentrated on experimental …

A Survey Of The Incidence Of Lupinosis In Sheep In The Dandaragan District In 1959, H G. Neil, W. J. Toms, C. M. Ralph

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

FOLLOWING widespread losses of sheep grazing on dry lupins, a survey of flockowners' experience with the disease was made by the Department of Agriculture in one of the districts most affected.

The idea of a survey originated from discussions with the President, Mr. K. E. Jones, and several other members of the Dandaragan Pasture Improvement Group.

The information obtained from the survey has provided a valuable factual basis for the design of laboratory and field experiments.

Milk Fever (Hypocalcaemia) Of Cows, Department Of Agriculture, Western Australia

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