Abstract

Effects of dietary levels of maize offal (MO) (0, 10, 20, 30, 40, and 50) on nutrient digestibility and mineral availability were investigated with 32-weeks old laying hens. Apparent dry matter, crude protein and cruse fibre digestibilities compared very favourably (P>0.05) in all dietary treatments. Apparent availability of calcium, magnesium, manganese, copper and iron was significantly (P<0.05) depressed as levels of MO increased in the diets. Phosphorus availability insignificantly increased with increasing levels of MO but that of potassium, sodium and zinc was relatively stable in all dietary treatments.
