| Current regulations for organic pig and poultry production systems permit feed ingredients of non-organic origin, primarily due to concerns that a 100 % organic diet would be unable to meet the demand for the essential amino acids lysine and methionine. 100 % organic diets for monogastrics will become compulsory in the EU from 1st January 2015, and so there is an urgent need to develop economically profitable feeding strategies based on organic feed across Europe. Feeding trials carried out with Gloucester old spot pigs in the UK found that there was no significant difference in the weight gains across the diets until the last week of the trial when there a significant difference in weight increase for the male pigs on the bean diet. This suggests that a... |

| The paper presents first year results of one participatory case study carried out as part of EU FP7 funded SOLID project (Sustainable Organic and Low Input Dairying) on an organic dairy farm managed with diverse swards and mob grazing in Britain. Mob grazing is a livestock management strategy consisting of high stocking density for a short time to remove forage rapidly due to high grazing pressure and then removing livestock to allow grass recovery. On the farm this is combined with a diverse sward, paying particular consideration to soil fertility. First results indicate that there was more available herbage in front of the cows, especially in the summer months, than could be expected from rotational grazing with shorter rest periods. Differences between... |

| Mob grazing is regarded as a grazing management practice to increase soil organic matter, pasture productivity and nutrient cycling. There are different perspectives in the literature regarding the definition of mob grazing, but it is generally accepted that mob grazing is characterised by high stocking densities of livestock which are moved frequently from paddock to paddock (e.g. with the aid of electric fences), trampling forage into the soil as they graze. It has also been recognised that biodiverse pastures have the potential to build up carbon levels in the soil much more effectively than conventional (usually monocultures) or less diverse pastures; in turn all can enhance animal productivity and maintain good herd health. This paper reviews the... |

| Organic farming is recognized as one source for innovation helping agriculture to develop sustainably. However, the understanding of innovation in agriculture is characterized by technical optimism, relying mainly on new inputs and technologies originating from research. The paper uses the alternative framework of innovation systems describing innovation as the outcome of stakeholder interaction and examples from the SOLID (Sustainable Organic Low-Input Dairying) project to discuss the role of farmers, researchers and knowledge exchange for innovation. We used a farmer-led participatory approach to identify problems of organic and low-input dairy farming in Europe and develop and evaluate innovative practices. Experience so far shows that improvements of... |
