Extract

Continued developments by plant breeders in the selection of rapeseed varieties with lower levels of antinutritive and toxic factors, especially glucosinolates in double-low varieties, has recently seen the commercial introduction of triple-low varieties. The characteristic yellow-coloured hulls of these newer types of rapeseed are considered to contain lower concentrations of other antinutritive factors found in the darker hulls of double-low cultivars. It is uncertain whether this has led to corresponding improvements in the nutritional value of the solvent extracted oil-free rapeseed meal (RSM) which is fed as protein supplement for livestock. This experiment was conducted to compare meal extracted from triple-low with that from double-low rapeseed as a protein supplement completely replacing soya-bean meal (SBM) in finishing pig diets.
