 Four experiments were conducted for investigation the effects of using different levels of some medicinal plants on carcass traits of female broilers. In each of these experiments 300 of 1 day -old broiler (Ross 308) from 1-42 days of age in two breeding period including starter 1-21 and grower 22-42 days of age were used in a completely randomized design in 5 treatments and 3 replicates (with 20 bird in each replicate). The amounts of each medicinal plant were 0 until 2 percent (0, 0.5, 1, 1.5 and 2%) from control until 5 experimental groups. The results of these experiments showed that except using artichoke, by using other three medicinal plants levels, there were significantly difference between treatment about the carcass traits (p<0.05). By using zizaphora the lowest percent of abdominal fat (2.18) was observed in group 5 whereas the highest percent of it (5.30) was observed in control group. In experiment contain nettle levels, the highest percent of thigh (26.69) was observed in control group and the lowest percent of it (22.87) was observed in group 5. About savory the highest and the lowest gizzard percents (3.81) and (2.49) were observed in control and group 2. Using artichoke did not have any significantly effects on female broiler carcass traits. The overall results showed that using different levels of zizaphora, nettle and savory medicinal plants could effectively improve the carcass traits of female broilers.
