  1. Expanding uses for oil meal and meal components Qasim Chaudry & David Turley 24 April 2009, Foggia, Italy

  2. Animal feed RSM c 40% protein Use limited by glucosinolates tannins sinapines high fibre content (non-ruminants RSM less palatable than soya – so blended Reduces bioavailability of proteins, minerals and vitamins, bitter taste + can taint produce

  3. Use of RSM • In large ruminants: up to 25-30% of concentrate intake can be as RSM • Sheep 10-30% of diet • Pig & poultry most sensitive • Esp to glucosinolate levels (decreased performance in piglets and finishing animals as RSM increases – but data very variable and depends on glucosinolate content (<4um/g glucosinolate can be fed at up to 30% of diet with no ill effects))

  4. Use of RSM • Broilers (meat) 10-15% dietary limit • Layers – bitter taint in brown eggs (from sinapine) • <10-15% in layers of white eggs • (breeding to remove defective gene)

  5. EU animal feed use • 122 million tonnes of compound feed consumed in EU – 27% is oilseed meal cake (33 mt) • 68% of this is soya meal • Only 9% is Rape Meal • Significant potential to increase RSM use in feeds (UK assessment suggests 50% increase) - but needs clear guidance !

  6. Alternative uses • Proteins (concentrates and fractions) (ph mediated salt extraction and diafiltration) • Glucosinolates (solvent extracted) • Pathogen control • Dietary benefits of isothiocyanates • Phenolics – sinapine (ph mediated or salt extraction and diafiltration or alternatively alkaline solvent (alcohol) extraction) • antioxidant properties • Removal improves value for other components (binds to proteins causing darkening) • Biocidal Proteins
