Feed that is given are corn, rice gran, soybean meal, coconut cake, PMM, fish meal, top mix TM and ginger powder in 17% protein and 2900 kcal/kg metabolizable energy. Statistic used in this research were Completely Randomized Design (CRD) Split Plot pattern with 4 treatments and 5 replications of diets (ad libitum provided), but on the ginger treatments feed gave once in three days, T0 = diets without using ginger powder, T1= 1% usage of ginger powder, T2= 2% usage of ginger powder, T3= 3% usage of ginger powder. The result show that native chicken relative weight of digestive tractus age of 12 weeks (T0= 13,16%, T1= 13,38%, T2= 12,51%, T3= 12,94), Length of small intestine (T0= 129,1 cm, T1= 123,9 cm, T2= 123,7 cm T3= 121,4 cm), relative weight of liver (T0= 2,42%, T1=2,33%, T2=2,53%, T3= 2,37%). The liver color of male native chicken with T0 treatment showed dark color (score 4), male native chicken with T0 treatment showed normal color (score 3) (descriptive). Gender of male didn’t make a significant effect on liver color. Gender of female makes a significant effect on liver color (based on H test from Kruskal Wallis).
