South Korea Country Profile 2005, Georgia Thomas

Farm Systems and Economics published reports

The Republic of Korea (South Korea) has a population of 48 million, with 12 million living in the capital of Seoul. The population is highly literate with Korean the main language and English taught widely in schools. South Korea is highly urbanised, with 81 per cent of the population living in urban areas. While there is a strong demand for traditional Korean style foods, there is an increasing trend towards western style products (led by the younger generations) with particular emphasis on healthy/well being products.

The land area covers 99,200 square kilometres (1.4 per cent of the size of Australia). …

Gross Margins Guide 2005 Western Australia, Allan Herbert

Farm Systems and Economics published reports

The Western Australian Department of Agriculture has prepared this 2005 booklet with the following aim:

To provide budgeting information for farmers, agribusiness, and other students of agriculture to enhance understanding and more informed decision making.

It builds on a previous similar booklet - "Gross Margins Guide 2003" - which was produced in 2002 with Commonwealth Bank sponsorship. 2,500 copies of that booklet were produced and gained wide readership. Gross margins for broad area agriculture had not been published by the Department for the previous 1 O years. Feedback and further requests suggested that an update was necessary - hence this …

Key Grazing Levels (Foo Targets) For Pasture And Sheep Management, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Food On Offer (FOO) is the amount of pasture in front of an animal, and is measured in kilograms Dry Matter per hectare. Managing pastures to key grazing levels - or FOO targets - can result in improved production of grazing systems in Mediterranean environments which are characterized by slow winter growth, peak spring growth and dry summers. These targets vary according to what production response is required.

This information sheet illustrates key target FOO for sheep grazing annual pastures during autumn and spring.

Marketing Locally Produced Foods: Consumer And Farmer Opinions In Washington County, Nebraska, Mindi L. Schneider, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Local food system potentials were studied in Washington County, Nebraska, United States. As a departure from most studies of locally based systems, farmers were surveyed in addition to consumers for potential participation. Data about the current food system and opinions and preferences for local production, marketing, and purchasing of food were collected using self-administered mail questionnaires. The response rate was 35% for the farmer survey and 37% for the consumer survey. Results indicated that, on the farming side of the food system, conventional corn and soybean production and marketing predominated in Washington County, and farmer interest in producing for local …

Miscellaneous Publication 19/2004 - Ord River Irrigation Area 2003 - Gross Margin Budget Guide For Horticultural Crops, Department Of Agriculture, Western Australia

Farm Systems and Economics research reports

Replaces Bulletin 4414

In 2000, Joanna Embry and Peter Gartrell, put together a Budget Guide for the Ord River Irrigation Area (ORIA). This document is an update with the objectives of updating some of those budgets to reflect current prices and yields. The two types of crops analysed are annual crops (cucurbits, field crops) and perennial crops (mangoes, bananas, and red fleshed grapefruit).

The analyses are prepared as guides of likely cost types and may not relate to individual growers. There is a wide range of fruit production systems, management techniques, varieties and market options making for a wide variation …

Free-Stall Dimensions: Effects On Preference And Stall Usage, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

In 2 experiments, free-stall dimensions were examined to determine how they affected stall preference, usage, cleanliness, and milk production in Holstein dairy cattle. In experiment 1, stall width (112 or 132 cm) and stall length (229 and 274 cm from curb to wall) were compared in a 2 × 2 factorial arrangement of stall treatments using 15 individually housed, non-lactating animals. Cows showed no clear preference for stall size as measured by lying time. When animals had no choice between stalls, average lying time was higher in the wide stalls than in the narrow stalls (10.8 vs. 9.6 ± 0.3 …

Miscellaneous Publication 8/2004 - Midas User Manual. Version 1, Ross Kingwell, Felicity Flugge, Emma Kopke, Michael O'Connell

Farm Systems and Economics published reports

What is MIDAS?

It's a computer model of dryland farming in Western Australia. MIDAS is an acronym (Model of an Integrated Dryland Agricultural System). Currently there are five versions of MIDAS, each describes a representative farm in a particular farming region of Western Australia. Versions exist for the following regions (see Figure 1):

• the Eastern Wheatbelt;
• the Central Wheatbelt;
• the West Midlands;
• the Great Southern; and,
• the South Coast.

Each of these versions is a mathematical programming model of a representative farm.

Fisheries Research Contract Report No. 6 - Assessment Of The Nutritional Variability Of Lupins As An Aquaculture Feed Ingredient, Brett Glencross, John Curnow, Wayne Hawkins

Fisheries Research Reports

The nutritional value of the kernel meals of three species of lupin (Lupinus albus, L. angustifolius and L. luteus) was compared against each other and a reference ingredient of solvent extracted soybean meal, when fed to rainbow trout (Oncorhynchus mykiss). Each lupin kernel meal was included in test diets at 300 g/kg and also at a greater level, representing 50% of the total protein content in the diet. The digestibility of protein of all lupin kernel meals was better than for the soybean meal. The highest protein digestibility was that from L. luteus kernel meal at 30% inclusion (100%), which …

Information On Pastoral Businesses In The Rangelands Of Western Australia, Department Of Agriculture, Western Australia

Farm Systems and Economics published reports

Edited by William Dalton and Francis Bright

The rangelands make up 87 per cent of Western Australia's landmass and include all but the south-west of the State. Livestock grazing on pastoral leasehold is the dominant commercial land use across 42 per cent (910,000 km*) of the WA rangelands and unallocated Crown lands comprise another 37 per cent.

The rangelands:

• Produce most of the State's mineral and energy wealth.

• Support important segments of the livestock industry.

• Are of special significance to the Aboriginal population.

• Offer major tourism potential.

• Contain essential elements of the State's biological diversity.

• Offer opportunities to produce horticultural …

Agroecosystems Analysis From The Grass Roots: A Multidimensional Experiential Learning Course, Mary Wiedenhoeft, Steve Simmons, Ricardo Salvador, Gina Mcandrews, Charles A. Francis, James W. King, David Hole

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

An intensive, experiential travel course in Agroecosystems Analysis was conducted in Iowa, Minnesota, and Nebraska (United States) during summers of 1998 and 1999. The intended student audience was advanced undergraduate and beginning graduate students. Pretravel readings and a week-long series of farm visits, which consisted of in-depth interviews with the farmers and their families, prepared student teams to analyze and evaluate the production, economic, environmental, and social sustainability of 10 farms. Students shared their analyses both orally and in written reports. Based on a multifaceted student evaluation process, we found that participants were highly motivated, strongly engaged with the course …

Effects Of Three Types Of Free-Stall Surfaces On Preferences And Stall Usage By Dairy Cows, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

One important criterion in choosing appropriate housing systems for dairy cattle is that the freestall provides a comfortable surface for the cow. This paper describes two experiments testing the effects of commonly used lying surfaces on stall preference and stall usage by Holstein cows. In both experiments, 12 cows were housed individually in separate pens. Each pen contained three free stalls with a different surface: deep-bedded sawdust, deep-bedded sand, and a geotextile mattress covered with 2 to 3 cm of sawdust. The animals were restricted to each surface in turn, in a random order for either 2 (Experiment 1) or …
