    • "Herbs have been used as human food and for medicinal purposes for centuries. It has been found that natural additives such as herbs, edible plants, some medicinal plant, medicinal plant extracts, plant products and isolated phytochemical constituents have been suggested as nontraditional feed additives or growth promoters in broiler diets to improve growth, feed conversion, immune response of birds, nutrient digestibility and reduce the cost of feed (Abaza 2001; Al-Harthi, 2002 and Abou-Sekken et al. 2007).El- Faham et al. (2015) stated that broiler chicks fed on basal diet supplemented with 250 mg thyme oil/kg diet gave an equal performance to control diet with improving bacterial media in small intestine and improving enzymes activity in ileum.

    ABSTRACT: Two hundred and forty broiler chicks at one day old of both Cobb and Avian strains were used in this experiment. Chicks weighted and randomly divided into four treatment groups of three replicates (10 chicks) for each strain to investigate the response of broiler chicks strain to some growth promoters supplementation (Amio-Flash, Bio-Strong and Bio-Feed) on growth performance, carcass characteristics and some blood plasma constituents as well as economical efficiency. The results indicated that:  Cobb chicks had consumed significantly higher amount of feed than Avian chicks. Broiler chicks fed diets supplemented with Amio-Flash recorded the highest values of live body weight (LBW), body weight gain (BWG), performance index (PI)and feed consumption (FC), also recorded best values of feed conversion ratio, protein conversion ratio (PCR) and calorie conversion ratio (CCR) than those fed other experimental diets. Interaction between strain and growth promoters supplementation had significant effect on LBW, BWG, PI and FC.  Percentages of carcass and total edible parts were significantly higher for Avian broiler chicks comparing Cobb chicks.  Cobb chicks had significantly higher plasma total protein, Globulin, cholesterol and AST constituents compared to Avian chicks., Also, cholesterol increased and A/G ratio decreased significantly by adding different growth promoters to the diets as compared to control. Interaction between strain and growth promoters supplementation had significant effects on all plasma constituents.  Feeding economical efficiency was improved for Cobb broiler chicks only by feeding diets supplementing with Amio-Flash than control. These results indicated that supplementing Amio-Flash as growth promoter to Cobb strain chicks could be used to maximize growth performance as well as economical efficiency without adverse effects on carcass traits during period (0-5 wks of age).

    • "P. harmala has antioxidant property (Jinous and Fereshteh, 2012) which reduce LDL oxidation and thereby reducing total cholesterol content. Abaza (2001) fed 2.5 kg P. harmala seeds and 2.5 kg chamomile flower heads per ton of broiler diet and observed reduced serum cholesterol as compared to the control group, which supported the findings of the present work. Similarly, Qazan (2009) added 10% P. harmala leaves to broiler ration and found the drop of serum cholesterol. "

    • "The feed consumption of the CR-fed group ( Table1) was higher than the feed consumption recorded by the other treated groups and the BD-fed group, and this is probably due to that coriander contains linalool essential oil which has appetizing properties in a diet and stimulating effects on the digestive process (CABUK et al. 2003). Moreover the chemical analysis of the coriander seeds showed it is rich in nutrients as that it contains 10.71, 14.83 ,7.10, 23.63, 8.91, 34.82% moisture, CP, CF, EE, ash and NFE (ABAZA ,2001).
