Feet and legs problem is one of the three major reasons for culling breeding pigs. Evaluation of feet and legs need a scoring method and this study attempted to set up a scoring method for pig selection system of Taiwan. For setting the linear scoring method of front and rear feet-legs, a total of 49 Landrace boars of seven auctions from members of Formosan Farmers Association for Swine Improvement and 86 Landrace boars of six terms from the Central Performance Test Station of National Animal Industry Foundation were scored. At first, a scoring form was set up, 100 total points, including 40 points of front legs (knee, front-leg turning, pasterns and claws) and 60 points of rear legs (angle-hock joint, rear-leg turning, pasterns and claws). Then we organized the working team for scoring feet and legs in breeding pigs. The members are Mr. Liu Kuei Chu, Mr. Lin Ko Yu, Mr. Yen Nian Tsu, Miss Chen Chia Hsuan and Mr. Wu Lian Fu. Each time three representative team members will score for feet and legs of breeding pigs, and Mr. Liu Kuei Chu and Mr. Lin Ko Yu served as chief umpire and vice umpire respectively. The scoring results will promote the swine breeding industry to enforce the structure of pig's feet and legs, and the scored feet and legs data will join as one of the information in breeding pig auction in the future.
