Animal feedRSM 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

• 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))

Use of RSM

Page 4: Expanding uses for oil meal and meal components

• 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)

Use of RSM

Page 5: Expanding uses for oil meal and meal components

• 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 !

EU animal feed use

• 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
