Abstract :

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 (p<0.05). The highest amount of daily feed intake (89.55 g) was observed in the control group and the lowest (80.11g) in experimental group 6, the lowest percent of abdominal fat (3.03) was observed in experimental group 5, the highest percent of breast (33.54) was observed in experimental group 7, the lowest level of blood cholesterol (100.97 mg.dl) was observed in experimental group 3 and the lowest blood triglyceride (38.37 mg,dl) was observed in experimental group 8. The overall results showed that using Nettle,Menta pulagum and ‌‌Zizaphora medicinal plants and their mixtures have positive effects on performance, carcass traits and blood biochemical parameters of broilers.
