the effects of artemisia dracunculus’ powders different levels on blood parameters and internal organs weight broiler chickens

this study was designed to investigate the effects of different levels of tarragon powder on performance, carcass characteristics of broiler chickens. two hundred ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. at each replicate ten birds were used. experimental diets were set on the basis of corn-soy-wheat and ross 308 broiler chickens nutritional requirements tables by the use of uffda ration formulation software for each of the (1-21 days) and (22-42 days) period. treatments were: base diet (control), base diet + 0.125% of tarragon powder (group a), base diet + 0.25% of tarragon powder (group b), base diet + 0.5% of tarragon powder (group c). the consumption of experimentally different rations (dietaries) had no statistically significant effect on the relative weight of heart, liver, spleen, bursa, cook able carcasses and abdominal fat of different treatments in the whole process of husbandry (p>0.05). testing rations in terms of calcium, phosphorus, glucose, cholesterol, triglycerides, vldl, ldl and hdl plasma didn’t create any significant difference between different treatments statistically ( p>0.05). we concluded that adding artemisia dracunculus powder 0.25 percentage broilers rations with increased levels of hdl, glucose and reduced levels of plasma ldl increased non- significantly carcass compared with other treatments. and also the level of 0/5 percent artemisia dracunculus powder has caused non- significant reducing of the weight of liver and carcass cook abdominal fat of broilers chickens
