Abstract

This study was carried out to investigate the influences of feed containing activated charcoal on the performances of calves The daily weight gain, feed intake, feed requirement and the content of ammonia in the excreta were measured. The experiment was conducted with 10 male calves for 30 days. Each were equally divided with treatment group and control group and for the treatment group's animal fed diets containing 1.0% activated charcoal. The daily weight gain of calves were decreased by 1.92% when they were fed activated charcoal(1.02kg/day) compared to that of control calves(1.04kg/day) and the daily feed intake of treatment group(2.86kg/day) was 10.06% lower comparing to the control group(3.18kg/day). In case of feed requirement, the result showed 8.2% lower in the treatment group(2.80kg) than control group(3.06kg). The content of ammonia in excreta was significantly lower for treatment group(0.33ppm) than control group (2.67ppm)(p<0.05), which showed more improvement for reducing ammonia content in the treatment group with 87.6%(p<0.05).

본 연구는 사료에 활성탄을 첨가했을 때 송아지의 일당 증체량, 사료 섭취량, 사료 요구율 및 배설물의 ammonia 함량에 미치는 영향을 규명하기위해 실시하였다. 홀스타인 수송아지 10두를 30일 동안 대조구, 시험구(활성탄 1%첨가)로 각 5두 공시하여 시험하였으며, 실험 결과를 요약하면 다음과 같다. 송아지의 일당 증체량은 대조구(1.04kg/일)에 비하여 활성탄을 급여했을 때(1.02kg/일) 1.92% 감소하였고, 일당 사료 섭취량은 시험구(2.86kg/일)가 대조구(3.18kg/일)에 비해서 10.06% 낮았으나, 사료 요구율은 대조구(3.06kg/kg증체)에 비해 시험구(2.80kg/kg증체)에서 8.2% 낮은 결과를 나타내었다. 송아지 배설물의 ammonia 함량은 대조구의 2.67ppm에 비하여 시험구가 0.33ppm으로 87.6% 감소되는 개선효과를 보였다(p<0.05).
