本試驗目的為，針對純種豬檢定之生長性能拈數、體型及腳蹄之名次進行相關性探討。試 驗豬隻為從 2011 年 3 月 23 日至 201 年 10 月 23 日止，共 254 頭財團法人中央畜 產會中央檢定站完檢之有腳蹄名次種豬。純種豬檢定拈數 100 以上進行體型評鑑，分品 種分性別體型評鑑有入選 2 頭(含)以上，再進行腳蹄評分，體型評鑑與腳蹄評分不同人 員進行。每個項目依照名次分成三且，再應用卡方分布與簡單相關性進行分析。試驗結果 如下:(1)體型、拈數及腳蹄三者之名次皆非獨立，就名次而言，體型與拈數、腳蹄與拈 數及腳蹄與體型之間的 Cramer's V 測定值分別為 0.57, 0.66 and 0.63，皆屬中高強度關聯。 (2)就名次簡單相關祥數而言，體型與拈數、腳蹄與拈數及腳蹄與體型之間的值分別為 0.57, 0.66 and 0.63。
關鍵語:種豬、相關性測定、名次

The purpose of this study was to examine the relationship of ranks among test index, body type, and hoof evaluation under swine purebred growth performance test. This study used 254 purebred swine with rank of hoof evaluation, which came from the Central Performance Test Station of National Animal Industry Foundation, the period was from March 23, 2011 to October 23, 2015. We evaluated body type from those purebred swine with test index up 100, then by sub-species and gender, if body evaluation has selected two (or more) purebred swine, to do hoof evaluation. Evaluation and review body type and hooves were by different personnel group. We divided the ranking of each item into three grades. The analysis tool was the Chi-Squared Test and Simple Correlation Test. The results were as follows: (1) According to Chi-Squared Test analysis , we rejected the hypothesis that the rank are independent among test index, body type, and hoof evaluation, As rank, the Cramer's V test values of X2 between test index and body type, test index and hoof evaluation and body type and hoof evaluation were 0.57,0.66 and 0.63, respectively. There was moderate high association between the three items. (2) The correlation of ranks between test index and body type, between test index and hoof evaluation and between body type and hoof evaluation were 0.40,0.46 and 0.37, respectively.
Key Words: Breeding pigs, Correlation test, Rank
