Oilseed rape variety and heat intensity during oil extraction impact on nutritional value ofoilseed rape co-products for pigs and poultry

摘要

Protein-rich oilseed rape (OSR) co-products are often used in farm animal diets, including pigs and poultry,with typical upper inclusion limit have long been assumed to be ~15% for rapeseed meal (RSM) in fattening pigs in theUK. However, more recent Canadian studies revealed greater levels of RSM derived from current OSR varieties in weanedpigs without performance penalties (Landero et al, 2011). Therefore, in this program of work, we revisited nutritional valueand recommended upper inclusion levels of OSR co-products using current UK OSR varieties for pigs and poultry, in orderto increase confidence in using OSR meals in pig and poultry diets as home grown alternatives for soya bean meal.
