The experiment was conducted to determine the nutrient digestibility and egg yolk pigment intensity of local
ducks which fed shrimps head meal, leucaena leaf meal and L-Carnitine supplement. The experimental method used was a
Completely Randomized Design (CRD) with four treatments i.e.: R0 (feed with leucaena leaf meal), R1 (feed with 25 ppm
L-Carnitine supplement), R2 (feed with 2% shrimps head meal) and R3 (feed with 4% shrimps head meal). A total of 0.20%
FeSO4/kg feed was supplemented to all treatments. The results showed that L-Carnitine supplements and fed shrimps head
meal (2% and 4%) have no significant effects (P>0.05) on crude fat and crude protein digestibility but have significant
