Good animal health and welfare is an explicit goal of organic livestock farming, and will need continuous development and adjustment on the farms. Furthermore, the very different conditions in different regions of Europe calls for models that can be integrated into local practice and be relevant for each type of farming context. A European project with participants from seven countries have been established with the aim of developing principles for animal health and welfare planning in organic dairy farming, based on a process where knowledge about the status within a given herd will be included as background for taking decisions and planning future improvements. An important part of the planning process is communication with other farmers as well as animal health and welfare professionals (veterinarians and advisors). Other principles such as systematic evaluation of how the improvements work in the farm ensure the continuity of the planning process. This presentation gives an overview over the current animal health and welfare planning initiatives in the participating countries and lines up the principles which are being gradually implemented in partner countries in collaboration with groups of organic farmers and organisations.

We have mapped the quality of pasture resources for sheep grazing outdoor all year on ten localities along the west coast of Norway, using a classification scheme developed for this purpose. The classes reflect fodder value throughout the year. We performed an accuracy assessment, and identified possible sources of error. The accuracy is relatively low, and like others, we found that separating heath classes is a challenge. However, most errors can be explained by special mislocation and temporal change. Our further work with exploring grazing habits and landscape use of Old Norse sheep will include a GPS study of sheep movements overlaid with our pasture maps. We will update the map on that locality through field visits to enhance its accuracy.

Markedet for ferdigplen har vokst, og mange leverandører har produkter å tilby. Kundene stiller ofte små krav til kvalitet, men kjenner verdien av en krone eller to pr kvadratmeter. Noen proffkunder i golf- eller fotballbransjen stiller store krav til kvalitet. De kjøper ferdigplen fra utlandet hvis de ikke finner den kvaliteten de må ha. Anleggsgartnere, som lever av marginer og har kunder helt uten kompetanse, kan fristes til å kjøpe ferdigplen av dårlig kvalitet. Men hva er kvalitet? Produsenten, anleggsgartneren og sluttbrukeren stiller helt forskjellige krav. Mens produsenten ønsker gress som raskt kan omsettes og selges uten at jordtapet blir stort, vil anleggsgartneren først og fremst ha lette ruller og grasmatter som henger godt sammen. Sluttbrukeren er opptatt av at gresset skal være ugrasfritt, etablere seg raskt og gi en varig, vakker og slitesterk plen.

Neutral detergent fiber, NDF, and the indigestible part, iNDF, were observed from market cultivars of Festulolium (Hykor, Felopa), Norwegian Festulolium candivars, the parent species perennial ryegrass (Lolium perenne) (cv. Napoleon, 4x), meadow fescue (Festuca pratensis) (cv. Fure) and timothy (Phleum pratense) (cv. Grindstad). Additionally leaf:stem ratio, developmental stage (msc) and total dry matter yield were observed. Field trials for dry matter yield assessment were established in 2006 at Vågønes (67°17"N, 14°27"E), Fureneset (61°34"N, 5°21"E), and Bjørke (60°48"N, 11°12"E) and for forage quality assessment at the two first mentioned locations. Genetic variation was identified for NDF and iNDF at early heading and heading stages between the investigated material. Highest content was found in cv. Hykor whereas in candivars only minor content was observed in leaves, however with higher content in stems. Promising candivars (FuRs0463, FuRs0357) from the Norwegian Festulolium breeding programme revealed better or equal to cultivars of their parental species as to content of NDF and iNDF. Winter survival which is a prerequisite for approved cultivars in Norway, was at an acceptable level in the candivars, and further breeding should preferably continue at the amphitetraploid level of the combination between perennial ryegrass and meadow fescue.

Nine filter beds have been constructed in the Nordic countries, Denmark, Finland, Norway and Sweden. Filter beds consist of a septic tank followed by an aerobic pre-treatment biofilter and a subsequent saturated flow grass-covered filter. Thus, filter beds are similar to subsurface flow constructed wetlands with pre-treatment biofilters. but do not have wetland plants with roots submerged into the saturated filter. All saturated filters contain Filtralite (R) P. a light-weight expanded clay aggregate possessing high phosphorus sorption capacity. The filter bed systems showed stable and consistent performance during the. testing period of 3 years. Removal of organic matter measured as biochemical oxygen demand (BUD) was >80%, total phosphorus (TP) >94% and total nitrogen (TN) ranged from 32 to 66%. Effluent concentrations of fecal indicator bacteria met the European bathing water quality criteria in all systems. One system was investigated for virus removal and somatic viruses were not detected in the effluent. The investigations revealed that the majority of the BOD and nitrogen removal occurred in the pre-treatment filters and the phosphorus and bacteria removal was more prominent in the saturated filters. The saturated filters could be built substantially smaller than the current design guidelines without sacrificing treatment performance. The used filter material met the Norwegian regulations for reuse in agriculture with respect to heavy metals, bacteria and parasites. When saturated with phosphorus, the light-weight aggregate. Filtralite (R) P used in the saturated bed is a suitable phosphorus fertilizer and additionally has a liming effect. (C) 2010 Elsevier B.V. All rights reserved.
