Abstract: An experiment was conducted to determine the digestibility of copper (Cu) by sheep fed high-level palm kernel cake (PKC) based diet. Fifteen cross-bred sheep were allotted to three groups and given PKC-based diet (Group I, control) or control diet + 1000 ppm sulphur(S) +20 ppm molybdenum (Mo) (Group 2), or control diet + 500 ppm Zinc (Zn). The apparent digestibility of Cu for sheep fed control diet was significantly higher (P<O.O 1) when compared with those in groups 2 and 3. The digestibility of Cu in lambs in Group 2 was the lowest (12.73%) compared to the other groups. On the other hand, the faecal excretion of Cu for sheep in Group 2 was the higher than the other groups. The highest urinary excretion of Cu was also observed in sheep of group 2 (0.53 ppm). It appears that the retention of Cu was reduced by when S + Mo was supplemented in the diet. The effect of Zn was less on both faecal urinary excretion of Cu in comparison with Mo+S.
