Abstract

Feeding ad libitum Napier grass with H3PO4 at 9.9 g P/day/animal (equivalent to dietary P concentration of 0.49 dry matter intake (DMI) or 28.96 g P/day/animal) did not improve appetite and feed intake of the animals as compared to the control (receiving 19.5 g/P/day/animal or 0.32 DMI). A significant depression of body weight changes (P0.05) was observed in treatment animals with the mean of 21.0 kg and 12.0 kg for the control and treatment groups respectively. No difference in plasma P concentration was found between groups. Phosphoric acid supplementation insignificantly increased the apparent digestibility of dry matter (DM) organic matter (OM) crude protein (CP) crude fibre (CF) ether extract (EE) Energy (E) Ca and Mg (except ash and P) but the retention of P was decreased (P0.05). The dietary P concentration of 0.49 DMI with a Ca:P ratio of 0.68:1 caused a depression in feed conversion efficiency and body weight changes. It was concluded that H3PO4 is not an acceptable source of P for swamp buffaloes
