The Effects of Different Levels of Nettle Urtica dioica L. (Urticaceae)Medicinal Plant in Starter and Grower Feeds on Performance,Carcass Traits, Blood Biochemical and Immunity Parameters of Broilers

This experiment was conducted to evaluate the effects of different levels of nettle (Urtica dioica) a medicinal plant in starter and grower feeds on performance, carcass traits, blood biochemical and immunity parameters of broilers. A completely randomized design was used with 324 broilers (Ross-308) divided in nine treatments and three replicates (with 12 birds in each replicate) 1 to 42 days. The treatment groups consisted of: (1) control group with no nettle supplementation, in other treatments the level of nettle in starter and grower feeds were, (2) 0.75% in both starter and grower, (3) 0 instarter and 0.75% in grower, (4) 0.75% in starter and 0 ingrower, (5) 1.5% in starter and 0.75% in grower, (6) 0.75% in starter and 1.5% in grower, (7) 0 instarter and 1.5% in grower, (8) 1.5% in starter and 0 ingrower, and (9) 1.5% in both starter and grower. The results showed that the use of different levels of nettle in starter and grower feeds had significant effects on carcass traits of broilers (P
