Abstract

본 연구는 잣 부산물의 급여가 육계의 생산성, 혈청 콜레스테롤, 도체특성 및 육의 지방산과 콜레스테롤 함량에 미치는 영향을 알아보기 위하여 시험을 실시하였다. 사양시험은 2일령 Arbor Acre Broiler(♂) 480수를 공시하였으며, 5주간 사양시험을 실시하였다. 시험설계는 1) CS(미루나무톱밥 1%), 2) PCM0.5(잣 부산물 0.5%+미루나무톱밥 0.5%) 및 3) PCM1.0(잣 부산물 1%)로 3개 처리를 하여 처리당 8반복, 반복당 20수씩 완전임의 배치하였다. 전체 시험 기간 동안 생산성은 처리구간에 유의적인 차이가 없었으며(P>0.05), 또한, 혈청 콜레스테롤 및 도체비율도 처리구간에 유의적인 차이가 없었다(P>0.05). 다리살과 가슴살의 TBARS는 PCM1.0처리구가 CS처리구와 비교하여 유의적으로 높았다(P<0.05). 다리살의 arachidate는 PCM0.5 처리구가 PCM1.0 처리구와 비교하여 유의적으로 높게 나타났으며, linolenate는 PCM1.0 처리구가 다른 처리구와 비교하여 가장 낮게 나타났다(P<0.05). 다리살, 가슴살 및 복강지방의 콜레스테롤 함량은 처리구간에 유의적인 차이가 없었다(P>0.05). 결론적으로 본 시험의 결과 육계에 잣 부산물의 급여는 TBARS에 영향을 미치는 것으로 사료된다. This study was conducted to evaluate effects of dietary pine cone meal on growth performance, serum cholesterol, carcass quality and fatty acid composition and cholesterol content of meat in broiler chickens. Three treatments were assigned to 480(2 days) Arbor Acre broiler chicks with eight replications, allocating 20 broiler chicks in each replication. Dietary treatments included 1) CS(1% cottonwood sawdust), 2) PCM0.5(0.5% cottonwood sawdust + 0.5% pine cone meal) and 3) PCM1.0(1% pine cone meal). During the overall period the difference of growth performance was not significant among treatments (P>0.05). Also, cholesterol profile(total, HDL, LDL cholesterol and triglyceride) in serum and carcass characteristic were not affected by treatments(P>0.05). TBARS of leg and breast meat was significantly decreased (P<0.05) in PCM1.0 treatment compared to CS treatment. In fatty acid contents of leg meat, C20:0 was significantly higher in PCM0.5 treatment than PCM1.0 treatment(P<0.05). Also, C18:3n3 was significantly lower in PCM1.0 treatment than other treatments(P<0.05). Cholesterol contents of leg, breast meat and abdomen fat were not significant among treatment(P>0.05). In conclusion, results of the experiment were affected by dietary supplementation of pine cone meal on TBARS of leg and breast meat.
