Investigating the effects of using Nettle (Urtica dioica ), Menta pulagum (Oreganum valgare) and Zizaphora (Thymyus valgaris) medicinal plants on performance, carcass quality, blood biochemical parameters and blood cells of broilers

This experiment was conducted to evaluate the effects of using Nettle,Menta pulagum and ‌‌Zizaphora medicinal plants on performance, carcass quality, blood biochemical parameters and blood cells of broilers. The experiment was conducted in a completely randomized design with 288 broilers (Ross-308) in 8 treatments and 3 replicates (with 12 birds in each replicate) from 1 to 42 days and included: 1) control group without using any medicinal plants, 2) 1.5% of ‌‌Nettle, 3) 1.5% of Menta pulagum, 4) 1.5% of Zizaphora, 5) 1.5% of Nettle and Menta pulagum, 6) 1.5% of Nettle and Zizaphora, 7) 1.5% of Menta pulagum and ‌‌Zizaphora, 8) 1.5% of Nettle,Menta pulagum and ‌‌Zizaphora. The results showed that using these medicinal plants and their mixtures had significant effects on performance, carcass traits and blood biochemical parameters of broilers (
