The effect of cold acclimation and defence activators on snow mould resistance and expression of pathogenesis-related (PR-) genes were investigated in winter cereals and perennial ryegrass. Cold acclimation, known to induce snow mould resistance, had apotentiating effect on snow mould-induced PR-gene expression in winter wheat. Chitosan treatment induced chitinase expression and in some cases also snow mould resistance in winter wheat. Bion treatment reduced snow mould resistance in perennial ryegrass.

Sheep and goat farming systems in this part of Europe are based on extensive use of non-fertilised natural pastures and a long barn-feeding period. One million ewes are kept for the production of meat and wool while 60,000 goats are kept mainly for themilk. The local demand for organic meat and milk is increasing gradually and 10 percent of the agricultural area is projected to be managed according to organic principles by 2010. This paper discusses the feasibility of introducing cashmere goats in an organic sheep farming production system, based on economical calculations in a Linear Programming model. Significant movements from sheep to cashmere goats production are entirely as slaughtering of eight months old kids (11 kg) is unprofitable, assuming equal labour input of goats and sheep. Yields of meat and cashmere could be improved by feeding the kids until 20 months (19 kg) so possibly making goats as profitable as sheep. The benefits of high value cashmere production and controlling bush encroachment by goats favour a mixed farming system. If yield-levels of roughage can be maintained at 75% without artificial fertilizers and challenges in housing of small ruminants are solved, a shift away from conventional farming is profitable given the current support for organic farming.
