This experiment was carried out to compare the effect of full feeding and restricted feeding on growth rate, feed consumption, feed efficiency, backfat thickness, and feed cost per 1㎏ of body gain with 8 barrows of Berkshire raised from weaning to about 90㎏ of body weight. The results obtained are as follows: (1) The number of days required to reach at 90㎏ of body weight was 170 days for the full feeding and 205 days for the restricted feeding. The average daily gain was 0.66㎏ for the full feeding and 0.46㎏ for the restricted feeding, and the difference was highly significant. (2) The amount of feed consumed from weaning to 90㎏ of body weight was larger in the full feeding than in the restricted feeding by 4% (p$lt;0.05). The amount of feed consumed per㎏ of body gain was 3.43 ㎏ for the full feeding and 4.28㎏ for the restricted feeding, and the difference was statistically significant (p$lt;0.05). (3) The average backfat thickness was 4.22㎝ for the full feeding and 3.32㎝ for the restricted feeding, but the difference was not significant statistically. (4) The feed cost per ㎏ of body gain was 117.5 won for the full feeding and 144.6 won for the restricted feeding, and the difference was statistically significant (p$lt;0.05).
