초록

This study was carried out to investigate the relationship between the physical dimensions of ear and age for swine. The physical dimensions of ear and weight for twenty pigs were investigated on 1, 20, 40, 90, 120, and 150 days of age, respectively. The thickness of ear was measured at the upper, middle, and lower part of fore perimeter, and the middle and lower part of hind perimeter. The length of ear was measured for width and height. The thickness of ear increased rapidly from 1 day to 20 days of age, then it developed gradually after that period of time. The thickness at the lower part of fore perimeter increased most rapidly from 1 day to 20 days of age. In the length of ear, width increased gradually whereas height increased rapidly from 1 day to 90 days of age and then they almost did not. All the regression equations between the physical dimensions of ear and age were best represented by $Y=a+b\;X^{0.5}$. These results suggest that RFID has to be installed on the middle part of hind perimeter and an ID chip has to be installed on the lower part of fore perimeter.
