Mælkens indhold af CLA er interessant ud fra en human ernæringssynsvinklen, idet flere undersøgelser har vist en positiv sammenhæng mellem indtag af CLA og risikoen for cancer. Der blev fundet en betydelig variation mellem bedrifter i mælkens indhold af CLA, og ikke noget entydigt billede af niveauet i konventionel og økologisk mælk. Resultater viser desuden at foderrationens sammensætning påvirker niveauet, men også at der synes at være en forskel mellem de enkelte køer. |

Boelt, Birte. |
The Danish Minister for Food, Agriculture and Fisheries presented in spring 2004 a bill on co-existence of genetically modified, conventional and organic crops in support of the free choice of consumers and to ensure development possibilities for new and existing production forms. The bill contains a framework for regulation based on crop specific control measures, communication among farmers and mandatory courses in GM cultivation. The identification of control measures is based on the report form the Danish analysis group and from the presentations and discussions at the First European Conference on Co-existence, GMCC-03. |

Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed. With the increasing area of GM-crop production as well as in the number of crops in which GM-varieties are available the need for guidelines to ensure coexistence are becoming increasingly essential.... |

Esse trabalho verificou as técnicas de colheita e armazenamento das variedades locais cultivadas nas roças de agricultores do Bairro da Serra - Iporanga/SP. Identificando a influência dessas técnicas na qualidade das sementes. A base da metodologia foi conhecimento do agricultor, por meio de entrevistas semi-estruturadas e abertas. Para sementes coletadas foram realizados teste de germinação, teor de água e massa de mil sementes. As informações obtidas foram analisas por meio de relatórios descritivos e análise descritiva. Os agricultores estudados têm profundo conhecimento das espécies de plantas que cultivam nas roças, ainda existindo elementos que os caracterizam no sistema de campesinato. Conseguem manter a qualidade das sementes de acordo com seus... |

Keeping sows in the outdoor pasture conveys high risk on environmental pollution through nitrate leaching which might be tremendously high in autumn and winter. Integrating grassland based free-range pigs with selected energy crops has been proposed as one possible approach to reduce nutrient leaching; however the effect has never been quantified. The ecoefficient pig farming that takes care of pig’s animal welfare and possible reduction of nitrate loss into environment may be achieved which will contribute to the Danish Green Growth Agreement of reducing up to 19,000 tons of NO3-N between 2010 and 2015. Apart from the main focus on NO3-N leaching potential, this experiment also investigated Nmin and phosphorus distributions at various soil depths and... |

The paper analyzes the structure and performance of beef cattle farms in Extremadura: Conventional (n = 50), Organic with no sales of organic products (n = 37) and Organic farms with sales of organic products (n = 11). Regarding stocking rate levels, no significant differences were observed among groups. By contrast, significant differences among the three types of farms regarding racial structure (p <0.05). Similarly, significant differences were found (p <0.1) in relation to farm's area, cattle's reproductive management and performance. The study highlights the similarity between conventional and organic cattle production in Extremadura. This fact could allow a smooth transition of conventional farms to the organic production model. |

This study is an exploratory research comparing the changes of body condition score, locomotion score and cleanliness score between pasture and indoor season in purebred Dutch Friesian, 75% Dutch Friesian, 50% Dutch Friesian, Holstein Bakels and Brown Swiss dairy cattle. The dual-purpose cows were expected to cope better with a change in season and harsher environmental conditions compared to specialized dairy cows. Therefore it was expected that the body condition of the dual-purpose cows would be closer to the optimum or even higher and would barely change over season. The specialized dairy cows were expected to cope less well on pastures and during a change of season, with a body condition under the optimum, higher prevalence of lameness and more dirt... |

Eight methods were used to estimate degree-days in four Colombian localities. Four methods have been previously proposed in literature: Simple Sine, Double Sine, Simple Triangle, and Double Triangle methods. The other four methods are proposed in this research: Simple Logistic, Double Logistic, Simple Normal, and Double Normal. The estimation of the degree-days through hourly temperature values was used as the reference standard method, and the four localities from where the temperature values were taken were the municipalities of Cajicá (Cundinamarca), Santa Elena (Antioquia), Carepa (Urabá Antioqueño), and Ciudad Bolivar (Zona cafetera Antioqueña). Degree-days obtained by all methods under study were compared through linear regression to those obtained... |

A enxertia é uma técnica alternativa freqüentemente recomendada para a cultura do pimentão em áreas infestadas com patógenos e para melhor produção. Objetivou-se avaliar a compatibilidade e o desempenho agronômico de pimentão enxertado sob sistema orgânico de produção. O delineamento experimental foi em blocos casualizados completos, com nove tratamentos e quatro repetições. Os enxertos de pimentão utilizados foram a cultivar Dulce All Big, Híbrido Satrapo e Híbrido Samurai, enxertados em três porta-enxertos de pimenta: Doce Comprida (Capsicum annuum), Doce Italiana (Capsicum annuum) e pimenta de Cheiro (Capsicum chinense), e as testemunhas Dulce All Big e Samurai. As variáveis analisadas foram: porcentagem de pegamento da enxertia, porcentagem de... |

Organic fanning is increasingly being seen as one sustainable option to farmers, among the alternatives to conventional input intensive farming systems. Uttarakhand in India is promoting organic agriculture state state through registering the farmers and providing them necessary support including marketing in crop sector. However, these registered organic farmers, who maintain two or more than two livestock species under crop-livestock mixed farming systems, not yet geared to organic livestock production per se. As 'organic' is a process claim rather than a product claim, the study on the compatibility of animal husbandry practices of registered organic farmers with the recommended organic livestock production standards, may provide an idea of the... |

Este estudo foi realizado com o objetivo de estudar o comportamento de vacas holandesas em lactação durante o período hibernal em pastagem constituída de capim-elefante (Pennisetum purpureum Schum.), aveia preta (Avena strigosa Schreb.) e azevém (Lolium multiflorum Lam.). As avaliações foram feitas em três ciclos de pastejo, em 17/06, 04/08 e 16/09 de 2004. Em cada avaliação, utilizaram-se seis vacas entre o 2o e o 5o mês de lactação. O registro de dados foi realizado por dois observadores das 18 às 6h e das 8 às 16h, a cada 10 minutos. As características comportamentais observadas foram os tempos de pastejo em capim-elefante e em aveia + azevém, em pastejo total (pastejo de capim-elefante + aveia e azevém), em ruminação e ócio. Concomitantemente,... |
