The aim of this experiment was to find the effect of supplementation of zeolit and
was to find the optimum level of zeolit in rations on quail performance. This experiment used
80 female Coturnix coturnix japonica of five weeks old with average body weight 145,44 ±
6,72 g (cv 4,62%). The data were analysed using Completely Randomized Design and
polinomial ortogonal test. The treatments was divided to four supplementation zeolit rations
treatment (0%,2%,4%,6%). Each treatment had five replication and each replication used
four quails. Results of this study indicated that supplementation of zeolit (0 - 6%) in rations
gave not significantly different (P ⥠0,05) to feed consumption but gave significantly different
(P < 0,05) to hen day egg production (Ŷ = 46,48 + 4,86X â 1,09 X2 ; 0⤠X â¤6 ; R2 = 0,90)
and significnatly different (P < 0,05) to feed convertion (Ŷ= 4,85-0,44 + 0,10X 2 ; 0â¤Xâ¤6;R2 =
0,97). Level supplementation zeolit 2,22% was optimum to hen day egg production (51,86%)
and level supplementation zeolit 2,09% was optimum to feed convertion (4,39).
