LB: lower bound; n: number; n.a.: not available; UB: upper bound; ww: wet weight; To calculate the feed intakes a 72% of dry matter content was used, as it is the usual dry matter content of a sugar syrup.
The 95th percentile estimates obtained on categories with less than 60 observations may not be statistically robust (EFSA, 2011). Those values were not included in this table.
For Data set B, LB and UB calculations were the same as all samples were quantified.
