The Effect of Different Levels of Tanacetum balasmita Medicinal Plant Powder and Extract on Performance, Carcass Traits and Blood Parameters of Broiler Chicks

This experiment was conducted to evaluate the effects of different levels of dried aerial parts powder and extract of Tanacetum balasmita (TB) medicinal plant on performance, carcass traits and blood parameters of broilers. Two hundred eighty Ross-308 broilers from 10 to 42 days of age were used in a completely randomized design in 5 treatments and 4 replicates (14 birds per replicate). The treatment groups consisted of a control group (1) with no dried aerial parts powder or extract of TBand experimental groups 2 and 3 contained 0.5% and 1% of TB whereas experimental groups 4 and 5 contained 0.1% and 0.2% of TB extract, respectively. Using different levels and forms of TB significantly affected the performance, carcass traits and blood parameters of broilers (P
