Sheep Production In 11 Western States, United States Department Of Agriculture, Economic Research Service

Agriculture

Net cash returns of U.S. sheep producers were positive for the past 18 years, yet the industry in 1986 experienced the largest declines in number of sheep farms and in sheep population since 1942. Per capita consumption of lamb and mutton has trended downward since 1962, remaining below 1.5 pounds for the past 13 years. The 1986 USDA Farm Costs and Returns Survey indicates that the major sheep production practices of shed and range lambing have not changed significantly since 1980, and losses from disease and predators are high. Sheep production requires more hired labor and operator time than any …

Alternate Day Protein Supplementation Of Corn Stalk Based Diets With High And Low Ruminal Escape Protein Sources, R. M. Collins, R. H. Pritchard

South Dakota Beef Report, 1991

Twenty-four crossbred wethers (88 ± .44 Ib) were utilized to determine optimal level of dietary CP when corn gluten meal (CGM) and soybean meal (SBM) based supplements were fed alternate days. Diets were arranged in a 2 x 3 factorial design with SBM and CGM fed at 8, 9 or 10% dietary CP. Supplements were top dressed on ground corn stalks at a rate of two times the daily required amount (19.78% DM basis). The collection term consisted of an 8-day total feces and urine collection. DM1 and DDMl were improved (P<.01) when CGM was fed and as dietary CP was increased by either supplement. Dry matter digestibility (DMD) decreased (P<.05) as dietary CP level increased. Neutral detergent fiber digestibility (NDFD) did not differ (P>.05) for protein source or dietary CP level. …

Getting The Best Out Of Weaner Sheep In The Eastern Wheatbelt, Sally Revell

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

A study of the growth of Merino weaner flocks over summer and autumn in Western Australia 's eastern wheatbelt during 1989 and 1990 has identified efficient weaner management strategies, and provided a basis for future research and extension needs of this area. The average liveweight of several weaner flocks was unexpectedly low at the start of summer. Weaner flocks may need to be supplemented before the start of summer to prevent undue weight loss at this time.

Nf91-29 Ringworm And Club Lamb Fungus, Doyle Wolverton, Ted Doane

University of Nebraska-Lincoln Extension: Historical Materials

Sheep exhibitors, as you prepare for summer shows, examine how you prepare your sheep for the show ring. Washing and shearing removes the natural lanolin and suint that protects sheep from getting some diseases. Anyone who shows sheep this summer should be aware of ringworm and a ringworm-like disease that can be transmitted from infected sheep to humans. One ringworm type disease, caused by a fungus, is currently being called "club lamb" fungus.

Animal Production From Tagasaste Growing In Deep Sands In A 450 Mm Winter Rainfall Zone, Chris Oldham, Greg Allen, Peter Moore, Bruce Mattinson

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

In 1985, Martindale Pty Ltd, Sir James McCusker's family company, signed a unique research contract with Professor David Lindsay of the University of Western Australia. The aim of the Martindale Research Project was to study ways of increasing farm productivity in the sheep-wheat zone of south-western Australia. A primary focus was the high cost of grain or hay used to fill the autumn feed gap in grazing systems.

However, it was not clear how or if tagasaste might be economically used to replace the grain and/or hay traditionally fed by hand to sheep and cattle in autumn.

New Technique Joins The Fight Against Footrot, Laurie Depiazzi, Mike Palmer, David Pitman

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

The diagnosis of footrot in sheep and goats is not an easy task. Two main techniques are used for diagnosis - inspection of diseased feet on a farm and laboratory testing of bacteria isolated from foot scrapings. The interpretation of the results obtained by these methods requires a good understanding of the various forms of footrot.

A new laboratory technique has halved the time taken to detect those strains of the bacterium, Bacteroides (Dichelobacter) nodosus, that cause each form of the disease.

The Productivity Of Western Australia's Wheat And Sheep Industry, Tim Coelli, Ross Kingwell

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

A popular economic lament is that Australian industries and workers are not as productive as they should be. Politicians and economic commentators preach the need for productivity improvement and workplace reform, and criticise inefficiency and lack of endeavour. Can such criticism be fairly levelled at farmers and agricultural scientists? What is productivity and how is it measured? What is the productivity of Western Australia's main agricultural industry — wheat and sheep farming? This article addresses these questions and shows that our wheat-sheep industry can be moderately proud of its productivity record

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.

Supplementary Feeding Of Weaner Sheep At Esperance, Julian Gardner, Peter Doyle

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

Cereal grains, particularly barley, have been the usual supplement fed to weaner sheep during summer and autumn along Western Australia's south coast. This area is a major barley producer, and weather-damaged and other feed quality grain have a ready use. High protein lupin seed, and to a lesser extent silage, have gained wide acceptance recently as alternative supplements. This article discusses the results of the first two of a series of supplementary feeding experiments at Esperance Downs Research Station.

Trees And Livestock : A Productive Co-Existence, Richard Moore

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

Trees, as part of farming can help to combat land degradation problems and produce a good economic return from timber at the same time. For example, there is now clear evidence that planting trees can help combat salinity by lowering water-table levels. Trees can also substantially improve overall farm productivity by providing shelter for pastures and livestock. The challenge is to find practical and economical methods of integrating trees and farming. A combination of widely-spaced trees and livestock is one promising method. This article describes the benefits of this type of agroforestry to farmers, suitable locations and how to practice …
