Abstract
The aim of present study to evaluate the effect of using coriander seed and rosemary leaves and a interaction on them in broiler diet on broiler performance. A total of 1080 broiler chicks , Ross-308 at one day old, were randomly allocated to nine treatment groups(T1,T2,T3,T4,T5,T6,T7,T8,T9) and each treatment group was distributed to three replicates with 40 chicks for each replicate . Chicks in the first and second treatment group were fed on diet supplemented with coriander seed at the level of ( 0.25 % and 0.50 % ) , respectively , while chicks in the third and fourth treatment were fed on diet supplemented with rosemary leaves at the level of 0.25 % and 0.50 % , respectively . Mixing of tow medical herb types (coriander seed and rosemary leaves) were added to fifth , sixth , seventh and eighth treatment . whereas chicks in the ninth treatment were fed on a standard diet and used as a control group. The data showed that there were no significant differences between treatments for both body weight and feed consumption at marketing age (6 weeks), while T9 significantly (p < 0.05 ) had the best feed conversion ratio in the last week of experiment(week 6) compared with another treatments .Also, T1 showed least mean in body weight gained than all treatments in this study. The fifth treatment significantly ( p < 0.05 ) recorded higher mortality percentage than T2 , T3 , T4 , T6 and T7 which gave less percentage of mortality , whereas not differ from other . For concerned with the accumulative performance , the T4 showed least means in feed consumption compared with another treatments studies , Whereas not recorded any significant differences between all treatments for feed conversion and weight gain . The T6 get significantly ( p < 0.05 ) least percentage of mortality than control group and other treatments in this study . In conclusion, diet supplementation with coriander seed and rosemary leaves had not affected significantly on weekly body weight gain, marketing body weight and feed conversion ratio. However, diet supplementation with medical herbs had reduced the mortality percentage and feed consumption significantly for broiler chicks.
