PEB system is more economical when compared with structures commonly used Hot rolled and welded light H-beam was introduced in the Standard Livestock Housing. This study suggested more economical technology for structural design by the reduction of live load, relief of deflection limit and reduction of importance factor. And, when applying wind Load as a result of examination with Low Rise Building Systems Manual considering open model, we can know that when the wind load is big, enclosed model is more stable than open model. In short, Suggesting more economical model and providing the method to reduce natural disaster, by the application of PEB system and the development of technology for structural design, are considered to strengthen the competitive power of farmhouse.

Even though the development of livestock industry in Asia and Australasia has brought the economic growth and thus elevated the living standard in these areas, it has also brought the pollution caused by the increasing amount of animal wastes. Among them, Japan probably is the first country that suffered from the animal waste pollution as early as in 1970s. Nowadays, the animal waste pollution has been a common problem for almost every countries in this region. To solve it, different measures and regulations have been implemented in many countries. In this paper, different methods for animal waste disposal are discussed, including: manure-bed animal housing, composting, anaerobic treatment, odor control, utilization of biogas, aerobic treatment, three-step process, N and P removal, land application, cultivation of algae, anaerobic treatment of dead animals. It is hoped that an animal industry without pollution can be achieved in the future.

Engineering phase of dairy housing systems has close connection with the milk produc- tivity of dairy cattle, the quality of milk, extension of dairy production systems, labor- saving in management of dairy cattle and the like. Moreover, the rate of investment of dairy housing facilities is of relatively high level, However, there has been almost no research effort for the improvement of engineering aspects of dairy housing systems in Korea. The purpose of this study is to find out general engineering problems and to recomm- end the improvement in dairy housing systems in Korea. Field survey by means of questionaire, direct measurements, taking pictures and sketching was conducted to get necessary information for the study. Kyung-ki Do region was firstly chosen for sampling area since it has included more than half of the number of dairy farms of the whole country. The results obtained are summarized as follows: 1. In overall dairy farm layout, the dwellings of workers were ignored in the light of sanitary environment 2. The layout of stalls in a dairy barn belongs mostly to the type of double-row face-out, which is compatible with the emphasis of manure disposal activities. 3. While the width and length of stalls were sufficiently close to the standard dimension, the width of mangers was much less than the standard dimension. 4. The width and depth of manure gutters and the width of working alleys were much. less than the standard dimension. 5. The mooring equipment was mostly in the classes of chain or rope. The watering equipment was not facilitated independantly except the one cese of using watercup. 6. The bucket milkers with one or two bucket milkers with the capacity of two cattles. each were used as milking equipment in most dairy farms. 7. There were only few milk rooms independently spaced from other space, in which the arrangement of milking equipment was much less than the standard condition. 8. The lounging ground area was averaged to be sufficient for the activity of dairy herd. 9. Silos for silage used during winter consisted of mostly bunker silos, trench silos and underground vertical silos. Ordinary vertical silos were considered for the farmers to be inconvenient for the labor saving. 10. From the view point of heat conservation and moisture removal within the dairy barns, windows were not flexible for the easy ventilation and ceiling part was not adequate for temperatur maintenance. 11. Waste treatment and disposal systems were not provided with most dairy farms, therefore the livestock waste pollution problems would be serious in the near future.

우리나라는 축산농가의 사육환경 개선을 위해 양돈 농가를 대상으로 새로운 동물복지형 사육기준을 도입하여 신규농가는 2019년, 기존농가는 2025년부터 적용 예정인 정책을 수립 중에 있다. 이는 임신 4주 이후 임신돈 스톨 사육을 제한하며, 조도는 40Lux이상, 암모니아 25ppm이하, 임신돈 사육밀도를 기존 $1.4m^2$에서 $2.25m^2$ 등으로 기준이 강화될 것이다. 동물복지를 100년 가까이 연구하여 적용하는 유럽의 경우, 동물복지형 양돈 도입을 위해 농가에서 활용할 수 있는 시설 및 사양관리 매뉴얼을 제공하여 전환 농가의 편이성 및 활용성을 높이고 있다. EU 자체 및 EU 내 국가별 독립적인 기준을 설정하여 돈사 내 동물복지 개선을 위한 바닥시설 기준을 정하여 농가에 적용하고 있는 실정이다. 하지만 국내의 경우 일부 선도 농가를 제외하고는 일반스톨을 사용하지 않는 사육방식에 대한 방법 및 기술이 전무한 상태이고, 사육면적 외의 모돈의 복지에 가장 크게 영향을 미치는 돈사바닥에 대한 복지수준에 대한 연구결과도 없는 실정이다. 따라서, 정부는 모돈 군사사육 정책변화에 대응 할 수 있으며, 농가의 어려움에 대한 최소화 및 활용 가능한 연구들이 필요하다. 즉, 농가의 시설전환 및 사양관리 매뉴얼 개발과, 동물복지 수준향상을 위한 모돈사 바닥에 대한 연구 및 모돈의 복지수준에 대한 평가 방법들에 대한 연구가 요구된다고 제언하는 바이다.
