This experiment was carried out to examine the supporting rates of fore- and hind legs to the body weight (BW) in growing pigs and sows. For this purpose, 16 castrated male and 16 female growing pigs of Landrace and 10 sows of Landrace×Large White were used. The supporting rate of the forelegs and that of the hind legs in growing pigs and sows were determined by using the measurement apparatus for BW of pig. The error of method for this measurement was 1.27±2.66% with high precision. The supporting rate of the forelegs to the BW at 30kg, 60kg, 90kg and 105kg of BW in growing pigs was 53.2±1.5%, 52.0±2.0%, 50.8±2.4% and 51.4±2.6% and that of hind legs to BW was 46.8±1.5%, 48.0±2.0%, 49.2±2.4% and 48.6±2.6%, respectively. The supporting rates of forelegs to the BW at 90kg and 105kg of BW in pigs were significantly lower than fhose at 30kg and 60kg of BW (P<0.05), white the supporting rate of hind legs to BW was significantly higher in pigs of BW of 90kg and 105kg. These results show that the supporting rate of forelegs to the BW was inversely related with the BW in growing pigs. On the other hand, the supporting rates of forelegs to the BW at 108th day of pregnancy and at 23 days after parturition in sows were 53.7±2.2% and 53.9±1.8% and those of hind legs to BW were 46.3±2.1% and 46.1±1.8%, respectively. There was no significant difference between the supporting rate of forelegs or hind legs at 108th day of pregnancy and after 23 days of parturition. This shows that the supporting rate of both fore- and hind legs was not affected by pregnancy in sows.
