Benzoic acid quadratically increased femur dry weight
(P=0.001), and linearly decreased ash concentration in the
femur (P=0.001),
but did not affect the total amount of ash in
bone in the present study (Table 7). Benzoic acid linearly
increased (Pb0.01) the concentration of P in bone ash and
quadratically decreased (Pb0.05) the concentration of Cl in
bone ash. Benzoic acid linearly reduced (Pb0.05) the concentration
of Ca in bone ash and linearly increased (Pb0.01) the
concentration of Mg in bone ash. Benzoic acid did not affect
the concentration of K and Na on bone ash. In chicks, bone ash
and Ca concentration increased following 3% propionic acid
inclusion in the diet (Ibardolaza et al.,1993), providing further
evidence that dietary acid inclusion and mineral nutrition are
related. Indeed, in rats the Ca concentration in bone increased
following the inclusion of 1.6% acetic acid (Kishi et al.,1999) or
2.5% L-lactic acid (Chonan et al., 1998) in the diet.
