DiscussionIngestion rates need to be calculated when water with a
WQC that is a PHCC such as Br is encountered. This is important
as it is the actual amount of PHCC ingested that is relevant,
and not the concentration in the water alone. The
cumulative intake of Br (mg/bird/day) over the 42-day
growth period was 1.591 (T2), 4.442 (T3), 0.093 (T4), 1.567
(T5) and 4.618 (T6) as published by du Toit and Casey (2010).
