Abstract

A total of 30 Korean native pigs (gilt 15, boar 15) were used to investigate the carcass characteristics, meat quality, amino acid, and fatty acid composition by gender. The carcass weight of boars were significantly higher than gilts, whereas the carcass yield of gilts had significantly higher than boars (p<0.01). Boars had significantly higher moisture contents in loin muscle than gilts, whereas the protein contents of loin muscle had significantly higher in gilts than boars (p<0.01). In the results of meat quality analysis, the cooking loss (p<0.01), shearing force (p<0.05), lightness (L) and yellowness (b) in meat color (p<0.05) were significantly higher, but the pH was significantly lower (p<0.01) in gilts compared with boars. Arginine (p<0.05), alanine, aspartic acid, histidine, leucine, lysine, phenylalanine, serine, threonine and tyrosin (p<0.01) for gilts were significantly higher than those for boars. The results of fatty acid composition showed that gilts had significantly higher contents of C16:1n7, C18:1n9, C20:1n9 (p<0.01) than boars in intramuscular fat, whereas boars had significantly higher contents of C18:2n6, C20:4n6 (p<0.01) and C18:3n3 (p<0.05) than gilts in intramuscular fat.

본 연구는 약 254일령(${\pm}2$)의 재래돼지 총 30두(암 15, 수 15)를 공시축으로 이용하여 성별에 따른 도체 및 육질 특성, 아미노산 및 지방산 조성을 비교 분석하여 고급돈육 생산에 필요한 기초자료를 얻고자 실시하였다. 도체중은 수퇘지가 유의하게 무거웠으나, 도체율은 암퇘지가 더 높게 나왔다(p<0.01). 등심부위의 일반성분 조성을 성별에 따라 비교한 결과, 수분 함량은 수퇘지에서 높게 나타났으며, 조단백질 함량은 암퇘지에서 높은 것으로 관찰되었다(p<0.01). 육질 특성을 분석한 결과에서 pH는 수퇘지에서 유의적으로 높게 나타났으나(p<0.01), 가열감량(p<0.01), 전단력, 육색의 명도와 황색도, 황색도(p<0.05)는 유의수준으로 암퇘지에서 높게 나타났다. 재래돼지 등심육의 아미노산 조성은 arginine (p<0.05), alanine, aspartic acid, histidine, leucine, lysine, phenylalanine, serine, threonine 및 tyrosin (p<0.01)의 함량이 암퇘지에서 수퇘지에 비해 유의적으로 높게 나타났다. 재래돼지 등심육의 지방산 조성은 암퇘지가 단가불포화지방산인 C16:1n7, C18:1n9, C20:1n9(p<0.01)의 함량이 수퇘지보다 유의적으로 더 높은 반면, 다가불포화지방상인 C18:2n6, C20:4n6 (p<0.01), 그리고 C18:3n3 (p<0.05)의 함량이 수퇘지에서 암퇘지보다 유의적으로 높게 관찰되었다. 결론적으로 본 연구는 재래돼지의 성별에 따른 도체 및 육질 특성, 아미노산 및 지방산 조성을 비교 분석한 것으로 앞으로 고품질의 재래돼지고기 생산을 위한 중요한 기초자료로 이용될 수 있을 것으로 사료된다.
