Effect of diets in different energy and protein levels on the fattenning performance and carcass traits of geesehas been investigated. Sixty goslings in 1-3 days old age were used in the experiment, in the starter period (0-4week) goslings were divided into 2 groups each containing 30 animals. A ration composed of 20% crudeprotein (CP) with 2900 kcal/kg metabolisable energy (ME) and ME/CP 145 were given to group 1 (G1) while group 2 (G2) received a ration containing 23% CP, with 3000 kcal/kg and ME/CP 130, in this period goslings which were fed with higher protein level gained 1518 g live weight (P<0.05) and their feed conversion efficiecy was better than G1. At the grower period (5-10 week), each group was further divided into subgroups each containing 15 goslings. G1 and G2 were divided into as G1A, G1B and G2A, G2B, respectively. G1A and G2A were treated with the rations containing 17% CP, 3000 kcal/kg ME, ME/CP 177 whereas G1B and G2B were treated with the rations containing 15% CP, 3000 kcal/kg ME, ME/CP 200. Different energy-protein ratio showed no effect on average live weights of groups at grower period (P>0.05). There was no statistical differences between the diet groups, in terms of carcass dressing percentage, carcass cuts and feather weight. It was concluded that diet contain 23% CP, 3000 kcal/kg ME, ME/CP 130 in starter period and 15% CP, 3000 kcal/kg ME, ME/CP 200 in grower period is sufficient for the geese reared in Kars region.
