This experiment was conducted to evaluate combination system of wood chip trickling system and activated sludge process. The results obtained are summarized as tallows. The trickling filter system using wood chip was used as a biological pre-treatment system for treating piggery wastewater. At pre-treatment the removal efficiencies were BOD $91\%$ CODmn $65\%$, SS $75\%$ T-N $73\%$, T-P $69\%$. After pre-treatment the removal efficiencies in activated sludge process were BOD $99\%$ CODmn $94.6\%$, SS $97.8\%$ T-N $91.1\%$, T-P $91\%$. This study shows a very stable method with pre-treatment of trickling filter using wood chip. These combined treatment system was very useful for piggery wastewater.

This study was conducted to analyze the technological levels of the domestic industries manufacturing the machinery and equipment for livestock production facilities and to lay out a scheme for upgrading the technical improvement. The results of this study are as follows : 1 . According to the study results, the technological levels of the domestic industries for livestock production facilities lag far behind those of the advanced countries in this field. 2. It was found that the ratio engaged in the areas of R&D was 10.7% and lower than that engaged in the other areas and the ratio of junior college graduated engineers engaged in the areas of research and design was 44.4%. Therefore, the amounts of investment for the areas of R&D and design should be increased. 3. In the design area, it was found from the study that the most weakness technologies which should be developed in near future were the universal harvester and the mechanical designing. Therefore, the multipurpose universal harvester suitable to the domestic farmland conditions should be developed and strength, hardness, and durability of materials in the mechanical designing should be improved.

This study was performed to evaluate the effectiveness of biological critical control points using the genetic profile of Escherichia coli isolates from pork cutting plants. Samples were collected from carcasses, equipment (knife, table, glove, transport belt, boning and skinning machine), the environment (wall and floor), and meat cuts during the cutting process from two plants. Pulsed-field gel electrophoresis (PFGE) was used to characterize the E. coli isolates. An identical genotype was detected from the carcasses, equipment, environment, and final meat cuts, and showed that the incoming carcasses, which were contaminated during transportation from slaughterhouses, were a major source of E. coli that was spread throughout processing. Also, consistent cross-contamination due to improper cleaning and disinfection procedures was another possibility. As a result, incoming carcasses and cleaning procedures should be considered critical control points in pork cutting plants, since a heating step is not used to inactivate microorganisms. Furthermore, the high rate (59.6%) of E. coli isolation indicates E. coli can be a good indicator in livestock processing plants even though it has genetic diversity.

Veterinary antibiotics have been widely used to increase feed efficiency, to prevent disease, and to promote growth as well as to control disease. The antibiotics administered can be excreted through the urine and feces. One of the major routes of veterinary antibiotics entering soil and water environment is via the application of animal manure to agricultural land as an organic fertilizer source. Since little is known about impacts of antibiotics on the environment, this study was conducted to prioritize the veterinary antibiotics based on the consumption and potential to reach the environment. Among 83 veterinary antibiotics consumed in Korea, ten antibiotics were used at the greater dose than 25 Mg in 2004. Potential to reach the environment was determined according to excretion rate after administered to animals and sorption affinity to soil solids after applied to agricultural land. Seventeen antibiotic active ingredients (Ais) were classified as 'High' priority in terms of the potential to reach the environment. An overall priority score was determined by combining priority score based on consumption with the degree of potential environment exposure. Twenty veterinary antibiotic AIs were classified as 'Very high' or 'High' priority requiring detailed assessment. The antibiotic AIs were identified four aminoglycosides, two macrolides, two penicillins, five sulfonamides, three tetracyclines, two quinolones, and two miscellaneous. Eight veterinary antibiotic AIs including amoxicillin, carbadox, chlortetracycline, neomycin, oxytetracycline, sulfamethazine, sulfathiazole, and tylosin were identified to have a greater priority of environmental risk in Korea.

환경부 고시인 '퇴비액비화기준 중 부수도 기준 등에 관한 고시'에 따라 내년 3월 25일부터 모든 축산농가에 대해 퇴비 부숙도 검사가 의무화된다. 3월 25일 이후에는 반드시 부숙 과정을 거쳐 축산 분뇨를 배출해야 하며, 허가대상 농가의 경우 6개월에 한 번, 신고대상 농가의 경우 1년에 한 번 분석시험기관에 가축 분뇨의 부숙 측정을 의뢰 분석해야 한다. 이를 어길 시 부숙도 부적합 정도에 따라 최소 50만원에서 최대 1,000만원의 과태료를 받게 된다. 축산농가들의 이해를 도와 실질적으로 대비할 수 있도록 퇴비 액비 부숙도 검사 내용과 전국의 부숙도 측정 기관 등을 소개한다.

There are a lot of trace gas of gaseous pollutants produced from farm animals. CO2 and CH4 are gases produced directly by the animal. NH3, N2O are produced from animal waste. Most of the effects of these gaseous pollutants on the farm animals have not been investigated in detail. CO2 emission from animal is very little. CH4 release from ruminant is also considered to be a significant factor in potential global warming. Nitrous oxide (N2O) emissions could be avoided by using organic or mineral fertilizer only as much as is needed by plant growing. This paper gives an overview about problems and solving strategies for possibilities for reduction of gaseous pollutants. The way to reduce the gaseous pollution risks from livestock systems are discussed.

The study exploited TAO system for the treatment of piggery slurry and aimed to draw characteristics and conditions of the reactor by differentiating the number of air input pump and foam cutter. The results are: 1. Under different operation condition, Run-3 with three air input pumps and four foam cutters showed the highest efficiency in the change of water level and temperature; 40-70cm and 45-55$^{\circ}C$, respectively. 2. Evaporation volume in Run-3 was the highest; 55.5l/$m^2$ . day in Run-1, 75.0/$m^2$ . day in Run-2, and 120.3/$m^2$ . day in Run-3. 3. Throughout the experimental period, temperature inside the reactor was maintained at around 5$0^{\circ}C$, regardless of seasonal temperature changes.
