Ano: 2012 URL: http://orgprints.org/21011/1/21011a.pdf Assessing the ecological soundness of organic and conventional agriculture by means of life cycle assessment (LCA) - a case study of leek production 21 de Backer, Eline; Aertsens, Joris; Vergucht, Sofie; Steurbaut, Walter. Purpose – Sustainable agriculture implies the ability of agro-ecosystems to remain productive in the long-term. It is not easy to point out unambiguously whether or not current production systems meet this sustainability demand. A priori thinking would suggest that organic crops are environmentally favourable, but may ignore the effect of reduced productivity, which shifts the potential impact to other parts of the food provision system. The purpose of this paper is to assess the ecological sustainability of conventional and organic leek production by means of life cycle assessment (LCA). Design/methodology/approach – A cradle-to-farm gate LCA is applied, based on real farm data from two research centres. For a consistent comparison, two functional...

Onions are known to contain high levels of flavonoids and a comparison of the efficiency, reproducibility and detection limits of various extraction methods has been made in order to develop fast and reliable analytical methods for analysis of flavonoids in onions. Conventional and classical methods are time- and solvent-consuming and the presence of light and oxygen during sample preparation facilitate degradation reactions. Thus, classical methods were compared with microwave (irradiation) extraction, ultrasonic liquid extraction and accelerated solvent extraction.

Production of organic beef from young cattle is not very developed in Denmark, in spite of a well-established organic dairy production with male off-spring. These calves are sold to conventional production, because of low performance in organic production systems. The purpose of this study was to test a concept for production of organic beef based on crossbred animals from dairy cows sired with a beef breed. The experiment included a comparison between spring-born pure-bred Holstein bulls (HB), crossbred Limousin x Holstein bulls (CB) and heifers (CH), 15 of each group. After weaning the calves were raised outdoor on pasture the 1st summer and indoor on a low energy grass-haylage ration over winter followed by pasture the 2nd summer and slaughter at a...

Crossbred Limousine x Holstein bulls and heifers may be an alternative to purebred Holstein bulls in organic beef production of young cattle because of the improved gain, carcass conformation and taste, but the fatness and texture of the crossbred bulls need to be improved through changes in the production strategy, especially feeding prior to slaughter, and in the pre and post mortem handling.

Ano: 2014 URL: http://orgprints.org/27063/7/27063.pdf Lebensmitteleffizienz der Österreichischen Nutztierhaltung - Bedeutung der Grünlandwirtschaft 21 Ertl, Paul; Steinwidder, Andreas; Schönauer, Magdalena; Krimberger, Kurt; Knaus, Wilhelm; Zollitsch, Werner. Der Beitrag der Tierhaltung zur menschlichen Ernährungssicherung wird aufgrund der ineffizienten Umwandlung von pflanzlichen Futtermitteln in tierische Produkte sehr kontrovers diskutiert. Das Ziel der vorliegenden Arbeit war es daher, anhand von nationalen Daten für die Jahre 2011–2013 den Beitrag von verschiedenen Tierkategorien (Rinder, Milchkühe, Maststiere, Schweine, Masthühner, Legehennen, Puten, Schafe und Ziegen) zur Netto-Lebensmittelproduktion in Österreich zu ermitteln. Rinder trugen als einzige Nutztierart sowohl bezüglich Energie als auch bezüglich Protein zu einer positiven Netto-Lebensmittelproduktion bei, das heißt sie produzierten über die tierischen Produkte mehr für die Menschen essbare Energie und essbares Protein, als sie in Form von...

O crescimento do mercado de alimentos livres de agrotóxicos vem gerando interesse de agricultores em sistemas orgânicos de produção. Os adeptos deste sistema promovem mudanças substanciais de seus métodos de produção, adquirindo conhecimentos técnicos e empíricos associados. São necessários, portanto, estudos para avaliar o sistema orgânico neste contexto, comparando-o com o modo de produção convencional, no que diz respeito aos aspectos socioeconômicos e ambientais. Este estudo teve como objetivo o diagnóstico regional desses aspectos em sistemas orgânicos e convencionais do distrito de Sussuanha, município de Guaraciaba do Norte, e do município de São Benedito, no estado do Ceará. Foram entrevistados sete agricultores orgânicos e 21 agricultores...

The comprehensive setof landraces, cultivars, and breeder-lines, were during their entire life cycle exposed to a two-factor treat-ment of combined elevated temperature (+5°C day/night) and [CO2] (700 ppm), as well as single-factortreatments of elevated temperature (+5°C day/night), [CO2] (700 ppm), and [O3] (100–150 ppb). Thecontrol treatment was equivalent to present average South Scandinavian climate (temperature: 19/12◦C(day/night), [CO2]: 385 ppm). Overall grain yield was found to decrease 29% in the two-factor treatmentwith concurrent elevation of [CO2] and temperature,...
