Abstract

Animals produce important co-products such as meat, milk, and egg. Higher consumption and urbanization asked for more animal products and the demand was so strong that lager livestocks are now being raised densely in small farm. Large production of excreta and maldor is an inevitable consequence of condensed breeding. If this malodor couldn't be controlled, it could be chief obstacle to development of both livestock industry and environment of future. Major odor produced from livestock environments could be subdivided into four major sections: volatile fatty acids, ammonia and volatile amine, indole and phenols, and sulfur compounds. More than half of nitrogen excreted urea, so low protein feeding, synthetic amino acid feeding and supplementing with digestive enzyme, microbial agents and/or probiotics are methods for reducing nitrogen excretion. A lot of studies about feeding and probiotics, co-feed have been researched to improve environment and/or productivity in livestock industry.

동물은 고기, 우유, 및 달걀과 같은 중요한 산물을 생산한다. 현대사회의 도시화과정 및 고도 성장은 보다 많은 동물성 산물을 요구하고 작은 농장에서 밀집화된 사육이 이루어지게 되는 원인이 되었다. 결과적으로 가축 분뇨생산량이 증가되었으며, 그에 따른 악취문제도 필연적인 결과로 나타났다. 분뇨로 인한 악취문제를 해결하지 못할 경우 축산업의 지속적인 발전과 환경개선을 이루는 큰 장애가 될 것이다. 축산환경으로 생산되는 악취는 휘발성지방산, 암모니아와 휘발성아민, 인돌과 페놀, 그리고 황화합물 네 종류로 분류된다. 질소성분의 절반이상은 뇨로 배설되기 때문에 동물을 사육하는 과정에서 저단백 사료와 합성아미노산을 급여시키고, 소화효소나 미생물제제 혹은 생균제를 사료에 첨가시켜줄 경우 질소원의 배출량을 감소시켜줄 수 있는 중요한 방법이 될 것이다. 따라서, 축산환경의 개선과 축산분야의 생산성을 향상시켜주기 위하여 사료 및 보조사료를 급여하는 다양한 시도가 진행되고 있다.
