Diet samples were collected once for crude protein, total
ash, calcium and phosphorus analysis according to
(Randhir and Pradhan, 1981; AOAC, 1985; David, 1976;
Cockerell and Holliday, 1975) while, ether extract was
determined according to Bligh and Dryer (1959)
technique as modified by Hanson and Olly (1963). Diets
pH was measured using electric digital pH meter Orion
research model 201, after adding 1 g of the diet to 9 mL
of dist. Water and mixing for 10 min and B-value
measured as milliters (mL) of 0.1 M HCl acid needed to
reach a pH of 5 in feed/water mixture (10 g of material in
100 mL of water).
