Broiler production development by plant herbs additive to support starter and grower diet

Abstract

Using two hundred and fourty one day old unsexed chicks meat type (Ross 308) and libitum feeding system was applied during the two rearing periods, starter period for 3 weeks and grower period for 3 weeks also were divided randomly to eight treatment with three replicate contain 10 chicks . The treatment of this experiment as follow as :(T1) control treatment without addition anything in feed (T2) adds 3 gm dried yeast per kg of feed (T3) add 3 gm chicory powder per kg of feed (T4) add 3 gmZingibel powder per kg feed (T5) add 1.5 gm dried yeast + 1.5 gm chicory powder per kg feed (T6) add 1.5 gm dried yeast + 1.5 gmzingibel powder per kg of feed (T7) add 1.5 gm chicory powder + 1.5 gmzingiber powder per kg feed (T8) add 1 gm dried yeast + 1 gm chicory powder + 1 gmzingiber powder per km of feed .Measure live body weight, body weight gain, feed consumption, feed conversation, mortility percentage and production index.Results indicated significant superioricy (p 0.05) for tretmentsT2 , T3 , T4 , T5T6 , T7 , T8in body weight , weight gain , feed effencity , production index and significant decreasing (p 0.05) in feed consumption compard with control T1at weeks 3 , 6 of age , T8 showed increasing singnificant (p 0.05) in body weight , weight gain , feed eiffiency , production index, and decreasing significant (p 0.05) in feed consumpticampard with all treatments at weeks 3 , 6 of age , The results indicated singnificant increasing (p 0.05) in body weight , weight gain , feed eiffiency , production index, and decreasing significant (p 0.05) in feed consumpticampard with treatments T2 , T3 , T4 , T7 at weeks 3,6 of age .No significant differences between treatments T5, T6 and between treatments T2, T3 , T4 , T7 in all prouductive performance at weeks 3 , 6 of age . it was concluded from this study we can add dried yeast , chicory powder and zingiber powder in self-time to feed , and the using the dried yeast , chicory powder and zingiber powder in the self-time increase body weight , weight gain , production index , decreasing feed consumption and improvement feed effiency
