Abstract

This study investigated the effect of bamboo salt (BS) on body gain, feed intake, meat composition, and blood characteristics of broiler chicks. BS was processed by roasting salt at $1,200{\sim}1,300^{\circ}C$ in a bamboo container, with the open end plugged with red clay. In total, 120 broiler chicks were assigned to four treatments. Each treatment was triplicated, with 10 chicks in each treatment group. The supplementation levels of the three BS-treated feeds were 0.1, 0.2, and 0.3%. Body weight gain slightly increased in broiler chicks fed diets supplemented with BS compared to that of the control during the overall test period. However, no significant differences were observed among treatments. Feed intake was also not significantly different among treatments. Feed efficiency was significantly (p<0.05) improved in broiler chicks fed diets supplemented with BS compared to that of the control. Body weight gain was more positively affected by the dietary BS supplement at the beginning of the experimental period than toward the end. Water intake was positively correlated with the dietary 0.3% BS level (p<0.05). Breast meat composition and cholesterol levels were also not affected by BS supplementation. The total protein, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol levels in the blood were not significantly different among treatments.

죽염은 우리나라에서 전래되어온 전통적 민간 의방의 하나로서 소화기 장애의 치료제로 사용되었다. 또한 염증, 당뇨, 순환기 질환, 바이러스성 질환 및 암 등 여러 가지 병의 치료에 효과적이라고 알려져 있다. 죽염은 여러 가지 광물질을 함유하고 있어 가축의 사육과정에서 생산성 향상에 영향을 미칠 것으로 사료된다. 따라서 본 시험은 3회 구운 생활죽염을 사료에 첨가 급여할 때 육계의 생산성에 미치는 영향을 규명하기 위하여 기초사료에 죽염을 0.1%, 0.2% 및 0.3% 수준으로 첨가 급여하여 육계의 증체량, 사료섭취량, 사료요구율, 도체성분 및 혈액 성분에 미치는 영향을 분석하고자 사양시험을 실시하였으며, 본 시험에서 얻어진 결과를 요약하면 다음과 같다. 육성전기에 생활죽염 첨가에 의한 증체량의 차이가 나타났으며 0.3% 첨가구인 T3구가 대조구에 비하여 9.6% 향상된 증체성적을 보였다. 사료요구율은 대조구에 비하여 죽염 0.3% 첨가구인 T3 처리구가 유의적으로 낮게 나타나, 약 2.6% 향상된 결과를 보였다(p<0.05). 또한 음수량과 분변 중 수분함량은 0.3% 죽염을 첨가 급여할 경우, 대조구에 비해 유의적(p<0.05)으로 증가하였으나, 닭가슴살의 일반성분, 복부지방함량 비율 및 혈액 성분은 죽염 첨가에 의한 유의적인 차이를 보이지 않았다.
