whereas urinary excretion of Phosphorus was not affected. As
reported by Mroz et al.
(1996, 1998), this will not affect the
retention of Ca due to an increase in the ATTD of Calcium in the
diets containing high levels of Ca benzoate.
Benzoic acid did not affect the ATTD and retention ofMg in
the present study (Table 5). In contrast, lactic acid in the diet
increased the ATTD of Mg (Kemme et al., 1999). Furthermore,
