bw: body weight; LB: lower bound; UB: upper bound; P95: 95th percentile.

^aFresh grass‐based diet (i.e. assumes no exposure to ZEN from forages).

^bGrass hay‐based diets.

Note that the exposures indicated with ^(b) assume that grass hay is the sole forage. Where fresh grass or grass silage are the main or sole forages, exposures are likely to be lower.
