가축 질병 발생시 신속하게 대처를 하지 못할 경우 그 피해가 막대하기 때문에 가축 질병은 축산업에서 매우 중요한 이슈이다. 가축 질병 발생으로 인한 문제를 해결하기 위해서는 가축 질병상태를 조기에 진단하고 체계적이며 과학적인 가축 사양기술의 개발이 필요하지만 국내에는 이러한 기술에 대한 연구가 미흡한 실정이다. 본 논문에서는 클라우드 컴퓨팅을 활용한 가축 질병 예찰 및 축사 통합 관제 시스템을 제안하고자 한다. 제안하는 시스템은 WSN과 어플리케이션을 통해 수집된 가축 및 축사관련 정보들을 데이터를 컬럼 지향 데이터베이스인 하둡 HBase를 이용하여 저장하고 관리하며, 맵리듀스 모델을 통한 병렬처리를 통해 가축 질병 예찰 및 축사 통합 관제 서비스를 제공한다. 또한 REST 기반의 웹서비스 제공을 통해 사용자는 PC, 모바일 기기 등 다양한 플랫폼으로 서비스를 제공받을 수 있다.

This survey was carried out to investigate the chemical characteristics of ground water for livestock purpose and to estimate the influence of ground water quality by livestock farming. Water samples were collected three times in 2000, and analyzed for theirs chemical compositions using Korean Standard Methods for Water Quality. The EC of ground water was from 0.214 to 0.474 dS/m. $NO_3-N$ contamination range was from 3.56 to 11.81. The $SO_4{^{2-}}$ was $4.31{\sim}69.37mg/L$ and CI was $12.75{\sim}41.46mg/L$. The data of ground water quality indicated suitable quality for livestock. Also, the concentration of heavy metals in the sample could not make damage to the animals. The $NO_3-N$ concentration of the water by times are as follows: October (8.19 mg/L) > July (7.65 mg/L) > April (4.04 mg/L) with no significant differences during the livestock farming period. The average quality of groundwater for livestock is good for its purpose, and it was showed there was few influence by livestock farming.

This study was carried out to investigate the Sacbrood virus (SBV) of Korean native honeybees causing serious damage in Jeonbuk area. Korean native honeybees completing the after overwinter 60 farms and March to April active phase adult bees and larvae 52 farms were collected from farms in 7 counties. Active phase of the adult bees 39 (75.0%) and larvae 24 (46.2%) farms was infected with SBV in 52 farms. This result indicate that SBV was the highest in Imsil-gun than other areas.

This article addresses issues related to environmental pollution.Particular attention is paid to the prevention of environmental pollution by livestock waste, which prompted the creation of closed ecological and biotechnical systems as environmentally closed production structures that can fit into the equilibrium system of the environment with minimal damage to it. An energy-saving and environmental protection technology for the processing and disposal of livestock waste with a maximum coefficient of energy transfer to livestock products has been developed, which consists in a combined treatment of waste in three stages, by transferring waste from one technological module to another, which makes it possible to completely utilize mineral substances in waste. The focus is on vermicultivation, microalgae cultivation and anaerobic fermentation in a bioenergy plant. To increase the productivity of growing microalgae, the authors proposed a deep type cultivator with submerged movable light sources.The technological parameters of the bioenergy installation for waste treatment are determined. An energy-saving and environmental-friendly technology has been developed for processing The main contribution of the study is the development of energy-saving and environmental technology for the processing and disposal of livestock waste with a maximum coefficient of energy transfer to livestock products.

구제역 등과 같은 질병은 전염력이 강해서 국가적으로 큰 피해를 유발하고 있는데, 이러한 질병을 조기에 감지하는 것이 중요하지만, 실제 현장에서는 체온상승 등 외관상의 증상을 통하여 감염을 인지하고 있으나, 초기에는 수의사들의 이동으로 인하여 병이 전염되는 사례도 있어 가축의 체온을 측정하여 이상유무를 조기에 발견하고 이를 원격으로 수의사와 연결하여 빠른 판단을 하는 것이 매우 중요하다. 본 연구에서는 유비쿼터스 ICT기술을 접목하여 IR센서를 이용한 한우의 체온을 측정할 수 있는 모듈을 개발하고 이를 기반으로 수의사와 농장주간에 원격진료시스템을 개발하여 한우의 건강관리를 할 수 있도록 하며, 유비쿼터스 ICT기술과 축산업의 융합을 통해 가축과 농장단위, 지역 및 국가단위의 관리를 효율적으로 할 수 있으며, 상대적으로 우수한 우리나라의 IT기술을 축산업에 성공적으로 접목할 경우 현재 우리나라 축산업의 지속가능성을 높이고, 세계 시장에서 기술 주도권을 확보할 수 있을 것으로 기대할 수 있다.

This study was designed to evaluate the possible DNA damaging effects of T-2 toxin using an alkaline single cell gel electrophoresis (SCGE) comet assay and also to investigate toxic effects in chickens. A total of 20 chickens were used in these experiments. Graded concentrations of dietary T-2 toxin (0, 4, 8, and $16{\mu}g/g$ of diet) were given to groups of 5 broiler chickens. In comet assay, The DNA damage was analysed by the tail extent moment (TEM) and tail length (TL), which were used as markers of DNA strand breaks in SCGE. A significant dose-dependent increase in the extent of DNA migration as well as in the percentage of cells with tails was observed after treatment with T-2 toxin (P<0.05). Treatment with the low T-2 toxin ($4{\mu}/g$ of diet) induced a relatively low level of DNA damage in comparison with the high T-2 toxin ($16{\mu}/g$ of diet) group. The growth rate was significantly reduced by concentrations of 8, and $16{\mu}/g$ of diet (P < 0.05). The feed conversion ratio were significantly affected by any concentrations (P < 0.05). The relative weight of the spleen, and lung was decreased by the growth inhibitory concentrations. The bursa of Fabricius, thymus, and kid- ney were decreased in relative weight by concentrations of $16{\mu}/g$ of diet. The relative weight of the liver and heart were unaffected. The hemoglobin (Hb), hematocrit (HCT), and mean corpuscular hemoglobin (MCH) were decreased at concentration of $16{\mu}/g$ of diet. As compared with control chickens, there was no marked change in serum components except uric acid in T-2 treated chickens. All lymphoid tissues retained atrophic and lymphoid cell depletion throughout the three weeks trial.

The purpose of this study was to investigate prevalence and antimicrobial resistance patterns of Campylobacter spp. from duck feces in northern area of the Gyeongnam province, Korea. Samples of 121 duck feces were taken from April to December 2014 for this survey. Samples were examined by bacteria isolation and reverse transcriptase-polymerase chain reaction assay for detection of Campylobacter spp. Campylobacter were isolated in 37 samples (30.6%). Among these samples, C. jejuni and C. coli were isolated in 35 samples and 2 samples, respectively. Minimum inhibitory concentration (MIC) test is performed to investigate antimicrobial resistance patterns of Campylobacter spp. C. jejuni were resistant to ciprofloxacin (85.7%), nalidixic acid(82.9%), tetracycline (77.1%), gentamicin (57.1%), azithromycin (40.0%), clindamycin (34.3%), erythromycin (22.9%), and florfenicol (8.6%). These data support a database of pollution and antimicrobial resistance of Campylobacter spp. from duck feces and provide a basic information of reducing the secondary damage of antibiotic misuse.

To evaluate composting process of piggery slurry, we made $1m^3$ bench scale composting reactor, and investigated the input and output of mass, moisture evaporation, volatile solid degradation, and running cost. For 15 days experimentation the results was as followed, The quantity of sawdust used was 0.47ton(18,000won) per 1ton slurry. The amount of moisture evaporated was 16.8kg/kg VS degradated. Total evaporation and VS degradation were 24.8%, 5.7% respectably. To analysis the running cost of that, we included only two factors, sawdust cost and compost income. The compost price to sell was 63won/kg(50% of market price) it made 8,694won income to 756 won loss, but 25won/kg, it was $13,650{\sim}23,100won$ loss per 1 ton slurry in the current pig farmer's condition. This cost was $8.5{\sim}14.4%$ of pig production cost and damage strongly to pig farmers to treat it.
