This study was conducted to evaluate the effects of supplementary pellet feed pellet on performance of Karkheh riverside nomadic sheep and goat flocks. Eight flocks (50 head per flock) were selected and divided in to two experimental groups (control and pelleted). Ewes and goats of control group, were fed according to traditional feeding system (As Is) where, the ewes and goats in experimental herds were received 300gr/d of supplementary pellet feed, during the last 45 days of gestation and 90 days of lactation. Average birth weight of lambs were 4.82 and 4.83 kg in control and experimental groups and the average birth wieght of kids were 3.59 and 3.67 kg in control and experimental groups that were not significantly different between the treatments. However, feed plett resulted in a higher weight gain of lambs and kids (P< 0.01). The average extra income per animal (ewe or dove) was 215577 Rials when used supplementary pellet feed.
