With single factor experiment design, 288 chickens with closed ankle color and 50-Day’s weight are divided into 6 experimental treatments randomly, each treatment has 3 repeats including 16 chickens. The experiment group is additived Abelmoschus esculentus into feedings by 2%, 3%, 4%, 5%(p<0.05), the control group has no Abelmoschus esculentus but additived Carophyll red & Carophyll yellow admixer. This experiment lasts 42 days. The conclusion shows: the pigmentation effects are significantly advanced on chicken skin and adipose by 3%, 4%, 5% Abelmoschus esculentus additive in experiment group, the pigmentation effects are not satisfied in control group and 2% Abelmoschus esculentus additive in experiment group. It needs 3 weeks from intaking Abelmoschus esculentus additive in feedings to yellow appearance in skin, after 4weeks to a satisfied degree. The pigmentation degree in different parts is: ankle>breast>adipose>back; the conclusion also shows Abelmoschus esculentus additive in feedings has no significant influence on daily gain and ratio of forage to body weight (p>0.05).
