This experiment was conducted to determine the effect of phase feeding on the growth, carcass characteristics and feed cost of pigs. Fifty four weanling pigs (Landrace × Large White × Duroc) weighing about 12.6㎏ were randomly allotted to 3 treatments(treatment Ⅰ : weaner-grower-finisher diets of 9-15-21 wk, treatment Ⅱ: 10-18-21 wk, treatment Ⅲ: 12-21 wk) for feeding trial. Each treatment consisted of 3 replicates and 6 pigs per replicate. Twelve pigs were slaughtered for determining carcass characteristics after the feeding trial. The results obtained are summarized as follows : There were no significant differences(P$lt;0.05) among groups in daily body weight gain, feed consumed, feed conversion and carcass quality. In the analysis of production economy, feed costs required per ㎏ of body weight gain for pigs fed weaner-grower-finisher diets of 9-15-21 wk and 10-18-21 wk were less than that for those fed 12-21 wk(P$lt;0.05).
