Assessing the differences in gross margins for a north-western Queensland beef-production system was undertaken using herd-budgeting software. The analysis reviewed the viability of producing beef for the domestic market from either a steer or bull production system. A hypothetical herd of 1200 breeders was created for the case study evaluation. An integrated beef production system from breeding to feedlot finishing was found to be less profitable for bull beef production than for steers at the current market prices. Although bull production was more profitable than steer production during the feedlot phase, the production of bulls in this phase failed to compensate for the earlier economic losses in the weaning phase of –AU$24.04 per adult equivalent for bulls. During the feedlot phase, bull production systems had lower break-even sale prices than did steer production systems. In reviewing two pricing scenarios for bulls, it was found that marketing bulls at the same price as steers was the most profitable production system. We conclude that the production of bull beef from a north-western Queensland production system can be profitable only if bulls can be sold without discount relative to steers.

SUMMARYCarbon footprinting is an increasingly important method of communicating the climate change impacts of food production to stakeholders. Few studies utilize empirical data collected from farms to calculate the carbon footprints of lamb and beef. Data from two farms in Wales, UK, were employed to undertake such an analysis for two system boundaries.Within a system boundary that considers the embodied greenhouse gases (GHGs) in inputs and on-farm emissions, producing 1 kg of lamb releases 1·3–4·4 kg CO2 eq/kg live weight (case study farm 1) and 1·5–4·7 kg CO2 eq/kg live weight (case study farm 2). The production of beef releases 1·5–5·3 and 1·4–4·4 kg CO2 eq/kg live weight.Within a wider system boundary that also includes GHG emissions from animals and farm soils, lamb released 8·1–31·7 and 20·3–143·5 kg CO2 eq/kg live weight on the two case study farms, and beef released 9·7–38·1 and 18·8–132·6 kg CO2 eq/kg live weight. The difference in emissions for this system boundary relates to nitrous oxides emitted from the organic soils on case study farm 2.These values overlap with nearly all other studies of GHG emissions from lamb and beef production. No direct comparisons between studies are possible due to substantial differences in the methodological approaches adopted.

AbstractAdditive manufacturing (AM) is a versatile technology that could add flexibility in manufacturing processes, whether implemented alone or along other technologies. This technology enables on-demand production and decentralized production networks, as production facilities can be located around the world to manufacture products closer to the final consumer (decentralized manufacturing). However, the wide adoption of additive manufacturing technologies is hindered by the lack of experience on its implementation, the lack of repeatability among different manufacturers and a lack of integrated production systems. The later, hinders the traceability and quality assurance of printed components and limits the understanding and data generation of the AM processes and parameters. In this article, a design strategy is proposed to integrate the different phases of the development process into a model-based design platform for decentralized manufacturing. This platform is aimed at facilitating data traceability and product repeatability among different AM machines. The strategy is illustrated with a case study where a car steering knuckle is manufactured in three different facilities in Sweden and Italy.

The cost of grazed grass is less than half that of grass silage (O’Kiely, 1994) and incomes from beef production are low and largely dependent on EU support schemes. Thus the income from beef production could be incresed by reducing feed costs through increasing the proportion of grazed grass in the diet and optimising the use of the various support schemes. The objective of this two-year study was to examine the effects on the performance of yearling cattle of turnout to pasture three weeks earlier than normal. This was examined within two suckler beef production systems. One was a standard system similar to that outlined by Drennan (1993) and the second was compatible with the Rural Environment Protection Scheme (REPS).

This article investigates the entrepreneurial beliefs/attitudes, ambitions, expectations, goals and visions of rural women who choose to cooperate and found Women's Rural cooperatives in the Prefecture of Heraklion on the island of Crete. The results of a qualitative study involving a sample of eight chairwomen of rural women's established Traditional Food Production cooperatives indicated that the traditional domestic roles (housewife, mother), the low level of education, the lack of professional skills, enterprise experience and mostly the unwillingness of rural women to undertake enterprise risk, have turned them toward an enterprise model that lacks modern business methods in the use of quality control production systems, in the production of Protected Geographical Identification Goods and/or Certified Local Traditional Food and/or Organic Products, in the use of new organizing and managing technologies, in advertising and promoting products and in administrative renewal.
