Organic husbandry aims to be based on 100 % organic feed. Currently there is a lack of protein feed for production of concentrates. Protein from oilseed crops is thought to complement the protein quality of peas (Pisum sativum L.). The experiences with oilseed crops in organic production are limited. With the ongoing project "Organic protein feed and edible oil from oilseed crops" the main aim is to obtain more knowledge of cultivation practices and the quality of the feed obtained from the crops. Spring turnip rape (Brassica rapa L. var. oleifera) and Camelina (Camelina sativa L.) are both successfully cultivated with different levels of supplied nitrogen and sulphur. Camelina seems to be an interesting new crop for organic production. It seems difficult to obtain good establishment and overwintering of winter rape (Brassica napus L. var. oleifera) and winter turnip rape. The nutrient value of organic spring turnip rape and winter turnip rape seems to be equivalent to conventional protein crops.

Animal welfare is regarded as a basic parameter in organic beef -and milk production. It is important to focus on good animal welfare at all levels, also including calves. Experiences from former projects show that calf welfare often represents a problem in organic and conventional farms, depending on the farmer"s priorities, attitudes and knowledge. A CORE Organic project "Minimizing medicine use in organic dairy herds through animal health and welfare planning" (ANIPLAN) was initiated in 2008 and is a collaboration between seven European countries, including Norway. The aim of the Norwegian project group, lead by the Norwegian Veterinary Institute, was to develop a calf welfare registration system, suitable for welfare advising and planning in organic milk production farms. The system focuses on animal based parameters, management, individual clinical score, colostrum intake and feeding system.

The aim of organic farming husbandry is to be entirely based on an organically produced diet. Pea is the most commonly cultivated protein rich crop in organic agriculture in Norway. However other high protein crops with complementary properties are needed to meet the nutritional demands in feeds for ruminants, pigs and poultry. An ongoing study in Bioforsk aims to develop cultivation practices on nutrient supply for organic oilseed crops and to establish knowledge on the feed quality of organically grown oilseed crops used as protein feed. It appears that spring turnip rape (Brassica rapa L. var. oleifera) and Camelina (Camelina sativa L.) can both be successfully cultivated with different levels of supplied nitrogen and sulphur. The nutrient value of organic spring turnip rape seems to be equivalent to conventional protein crops. Camelina can be an alternative in organic production, due to fewer problems with harmful pests compared with the traditional oilseed crops rape and turnip rape. Oilseed cake of turnip rape has higher protein and mineral content than the seed, and can be an interesting addition in feed ration for both ruminants and poultry, especially in combination with field pea.

The effect of climate on production and the quality of bilberries have been studied in a controlled experiment using clonal material. In the experiment individual plants from two northern clones and two southern clones of bilberry have been grown on 12◦ and 18◦ C. At each temperature 3 different light treatments have been tested; 1) 24 hour (h) natural light (long day); 2) 24 h natural light with addition of red light and 3) 12 h light (short day). All plants were kept outside during flowering to ensure pollination by insects. Berries were sampled when ripe, weighed and stored at -80◦C for later analysis of pH, sugars, acids, total phenols, total anthocyanins and total antioxidant activity.

Wild berries are a charcteristic part of the Northern nature and a potential speciality of Nordic countries. Wild berries are also a valuable resource that has not yet been exploited in a satisfactory level. Approximately 90-95 per cent of the wild berry crop yield is left unpicked in the Nordic forests every year. The challenges of the wild berry utilization are similar in the Nordic countries - the logistics of berry picking including traceability, fragmented sector structure as well as the high share of unprocessed raw material in export. The Nordic project focusing on biberry (Vaccinium myrtillus) "Bilberry: Towards functional food markets" (2007-2009) is part of the New Nordic Food programme funded by the Nordic Innovation Centre. The aim of the project was to promote Nordic cooperation between representatives from universities, research institutes and industry in order to improve wild berry production and utilisation on the Nordic and global market. To achieve this goal a network between the Nordic experts of the different fields of the wild berry sector has been established. The project has focused on marketing research, quality issues, biodiversity and traceability of wild berries, especially bilberry. The results of the marketing survey were first published in the Nordic Wild Berry seminar in November 2008. The aim of the survey was to generate an overall picture of the companies working with wild berries in Nordic countries and gather information on the existence and willingness of the berry companies to cooperate for instance in wild berry supply, logistics, marketing or research and development. According to the results, a general agreement for the need of increased cooperation at the Nordic level was highlighted.
