Abstract

This study was conducted to investigate the influence of dietary activated carbon(0.9%) and fish oil(0, 1, 2, 4%) addition on the feed efficiency, blood-cholesterol, proximate composition, pH and minerals in breast and thigh of chicken meat. Broilers were randomly assigned to one of the five dietary treatment: 1) Control (commercial feed) 2) T1(commercial feed supplemented with 0.9% activated carbon) 3) T2 (commercial feed with 0.9% activated carbon and 1% fish oil) 4) T3 (commercial feed with 0.9% activated carbon and 2% fish oil) 5) T4 (commercial feed with 0.9% activated carbon and 4% fish oil). They were fed with one of the experimental diets for five weeks and slaughtered. After that, the meat samples were vacuum packaged and stored over a period of 10 days at 4$\pm$1$\^{C}$. When broilers were fed with dietary activated carbon and fish oil, the feed efficiency of birds were higher compared with that of control diet. The blood cholesterol was tended to decrease in dietary activated carbon and fish oil(p<0.05). However, effects of diets containing graded levels of activated carbon and fish oil on proximate composition were not found(p>0.05). The pH of all treatments significantly increased during the storage periods. The activated carbon and fish oil diet increased the calcium, potassium and sodium content of chicken meat, and tended to increase total mineral contents.

활성탄 0.9%와 오메가 3계열을 다량 함유한 어유를 급여 수준(0, 1, 2, 4 %)에 따라 5주간 급여하면서 사료효율을 측정하였으며, 5주째 도계하여 혈액 콜레스테롤, 일반성분, 무기물을 분석하고 pH의 변화는 4$\pm$1'E의 냉장고에 진공포장하여 저장하면서 10일간 조사하였다. 사료효율은 2, 3주는 약간 증가하였으나 4, 5주째는 증가하지 않았고, 혈액콜레스테롤은 어유 첨가구에서 대조구에 비하여 낮아지고 있었다. (p<0.05). 일반성분은 활성탄과 어유 첨가구에서 큰 차이가 없었고(p>0.05), 단백질은 흉심부위가 대퇴부위보다 약간 많았다. p보는 저장기간이 경과하면서 전 처리구에서 유의적으로 높아지고 있었으며(p<0.05), 활성탄과 어유 첨가구에서는 높은 경향이었고, 무기물은 활성탄 첨가구가 대조구보다 많았으며 활성탄과 어유를 함께 급여한 구는 어유 첨가량이 많을수록 무기물 함량은 약간 적었고, 부위별로는 흉심부위가 대퇴부위보다 많았다.
