Abstract

The present study was conducted to investigate the effects of dietary supplementation with bamboo charcoal (BC) and bamboo leaf (BL) on growth performance, feed intake, feed conversion efficiency, and meat quality in broiler chickens. Broiler chickens were fed for 30 days with a diet containing 0.5% bamboo charcoal or bamboo leaf. The results showed that the mortality rate during the study period was slightly lower in the BC and BL groups than the control group, while terminal weight and weight gain were significantly higher in the BC and BL groups than the control group. Dietary supplementation with BC or BL also improved feed conversion rate compared to chickens in the control group. Shear force was significantly lower in the BC and BL groups than that of the control group. The fat content of chickens fed with BC tended to decrease, while the ratio of unsaturated fat acid of chickens fed with BC or BL tended to increase, although without a statistically significant difference. Sensory evaluation revealed that overall acceptability was slightly higher in the BC and BL groups than the control group. There was no statistically significant change in the hematology and serum biochemistry parameters, compared with the control group in any group tested. The results of this experiment indicated that dietary supplementation with BC and BL may improve growth performance, feed conversion efficiency, and meat quality in broiler chickens.

본 연구는 대나무 숯과 대나무 잎의 급여가 육계의 성장과 사료효율 및 육질에 미치는 영향을 조사하기 위해 30일간 각각 0.5%의 농도로 급여하였다. 시험결과, 대숯과 대잎 시험군에서 시험기간 중 사망률은 대조군에 비해 낮아진 반면, 출하 시 체중과 증체량은 대조군에 비해 유의성 있게 증가하였다. 또한 대조군에 비해 대숯과 대잎 시험군의 사료효율도 개선되었으며, 계육의 전단력은 대조군에 비해 유의성 있게 감소하였다. 대숯을 급여한 닭에서의 지방함량은 통계학적 차이는 없었으나 감소경향을 나타낸 반면, 대숯과 대잎을 급여한 닭에서의 불포화 지방산 비율은 증가경향을 나타내었다. 계육의 관능검사 결과, 대숯과 대잎 시험군의 선호도는 대조군에 비해 높게 나타났다. 혈액 및 혈청생화학 검사항목에서는 대조군과 시험군간에 유의성 있는 차이가 인정되지 않았다. 본 시험결과는 대나무 숯과 대나무 잎의 사료첨가 급여가 육계의 성장과 사료효율 및 육질을 개선시키는 것으로 나타났다. 본 연구결과는 사료첨가제로서 대나무 숯과 대나무 잎의 유용성과 개발가능성을 시사해 주고 있다.
