Abstract
This study was conducted to under seek the incidence of some neurotransmitters in drinking water and native medicinal flowers (Alecea Kurdica – Gule Hero and Chamomile) flowers as diet additives on body growth and immune of broiler. 720 one day unsexed hatched chicks will distributed into 12 treatments, each treatment with three replicates (20 chicks), as following: T0 (control -standard diet), [T1 (0.2 g Endorphin), T2 (0.2 g Dopamine) and T3 (0.2 g Serotonin)/ L drinking water], [T4 )0.5 kg Hero flower) and T5) 0.5 kg Chamomile flower)/ 100 kg diet], T6 )0.2 g Endorphin+0.5 kg Hero flower(, T7 (0.2 g Dopamine+0.5 kg Hero flower(, T8 )0.2 g Serotonin+ 0.5 kg Hero flower(, T9 (0.2 g Endorphin+0.5 kg Chamomile flower), T10 (0.2 g/ Dopamine+0.5 kg Chamomile flower), T11= 0.2 g/ L Serotonin/ L drinking water + 0.5 kg Chamomile flower/ 100 kg diet. The addition of neurotransmitters and native flowers additives as immune modulator had significantly affected on body weight, body weight gain and production index and led to to significant increase (P≤ 0.01) in relative weights of spleen, Bursa of fabricius, Thymus and antibodies titer against ND and IB diseases, also decreased the stress ratio which represented by heterophil/ lymphocyte (H/L) especially in T3 and T11.
