4 Irish Grazing System Characteristics Irish grasslands characterised by high pasture productivity potential, low variability in seasonal supply and quality Home produced feed and sustainable Volatile product prices and rising costs Increased grazed grass proportion decreases unit cost of production reducing feed, labour and capital investment costs Cost of alternative feeds: c/kg DM Relative Grazed grass Grass silage Concentrates Forage crops

9 Important assumption The vast majority of milk and meat produced in Ireland for the future will be from pasture-based systems Reasons: Pasture-based system has both a comparative and competitive advantage (Dillon et al. 2005) Pasture-based systems have greater sustainability: Economic- family farming business Social- both internal and external Ecological- climate, water, soil, fauna & flora Dairy products from pasture-based systems are of superior nutritional value (O Callaghan et al. 2017) 9

10 Grazing systems versus indoor based systems Grazing Systems Indoor Systems Grazing Utilisation Conservation based (harvesting/zero grazing) >200 days at grass days at grass Medium milk production per cow High milk production per cow Low fixed and variable cost High fixed and variable cost Minimum to low building investment High level of buildings investment Machinery minimum/high contractor usage Labour flexibility/mindset open Seasonal workload Resilient systems consistent margins Machinery high requirement/little contractor usage Labour routine/mindset closed All Year round workload High risk system exposed to milk price variations 10

12 Irish dairy production 7.25 billion litres approx. (2017) 18,351 dairy farmers, averaging c 400,000 litres Average constituents. 4.09% fat, 3.51% protein 91% of milk produced in spring calving herds 85% of total production is exported 10 milk processors (Co-op and Co-op/plc) 16 milk purchasing Co-operatives 12

21 Grassland improvements Sustainable intensification from grassland need to make farms MORE self sufficient from grass Grassland utilisation is a key predictor of PROFIT (need to move grass utilisation on farms) Grass requires focussed management need prediction models for GROWTH Grassland INFRASTRUCTURE needs to be modernised Soil NUTRIENT management, nitrogen, phosphorus and potassium Continual requirement for ANIMALS suited to grazing systems (production, fertility, calving interval) 21

22 Grassland improvements Grass breeding ON FARM performance Clover has untapped potential Grassland needs to embrace SMART TECHNOLOGY for management, use of big data and applications to management Research and knowledge transfer need to be FARMER agenda driven (are we really focussing on grass) In Ireland we have huge possibilities to utilise grass better 22
