Presentation Overview
• Background
• Cost of maize silage
– Effect of yield variation
– Effect of polythene mulch
– Effect of soil nutrient status
• Costs of alternative winter feeds relative to purchased
rolled barley
• Conclusion
Background
• Feed cost is the greatest direct cost (Teagasc NFS,2008)
• Need to control/ reduce feed cost
• Need to evaluate factors affecting feed crop cost:
– Changing input prices
– Management
– Soil and weather
• Grange Feed Costing Model (GFCM; Teagasc Grange 2010)
Analysis assumptions
• Soil index 3 for P and K
• High standards of management assumed (yields & quality)
• Annual land charge of €300/ha for all crops
• Current contractor charges for all operations (Teagasc, 2010)
• All chemical fertilisers used (Coulter & Lalor, 2008)
• Jan 2010 fertiliser and spray prices (CSO, IFJ, Teagasc 2010)
• Purchased rolled barley costed at €150/t fresh delivered
• Costs per hectare, per tonne utilised (consumed) dry
matter, per 1,000UFL

Effect of soil nutrient status and slurry usage
• Field 1: High P and K status. Previously permanent grassland.
• Field 2: Low P and K status. Previously in continuous maize/cereals.

Conclusion• Yield is the greatest factor affecting feed cost variability
• Soil nutrient status and testing is important
• Plastic important for maize, particularly wrt crop quality
• There are range of cost competitive winter feeds
• Range of factors affect the choice of feed crops
including:
– Cost of production and feeding
– Livestock feed requirements
– Farm layout
– Available facilities and labour
