구제역과 같은 가축 전염병은 강한 전염력으로 인해 막대한 경제적 손실을 초래하고 있다. 가축의 전염성 질병은 조기 감지가 매우 중요하나, 개별 농가에서 조기 진단이 어렵고, 수의사나 사료 공급 차량 등의 농장간 이동을 통해서 전파되는 사례도 빈번하다. 본 연구에서는 발병 초기단계에서 유비쿼터스 기반의 정보통신기술을 이용하여 가축의 체온을 자동으로 모니터링 하여 실시간 전송함으로써 수의사의 농장방문 없이 빠른 진단이 가능하고 추가 확산을 방지하는 기술을 연구하였다. 자동으로 수집된 정보와 연계된 원격진료시스템을 활용하여 농장단위, 지역단위, 국가단위에서 가축전염병을 커뮤니티 매핑 기법을 이용하여 체계적으로 관리하는 기술을 제시하였다. 이 과정에서 사용자 참여형 공간정보기술 적용을 위한 각 단계별, 주체별 커뮤니티 매핑 항목을 도출하였다.

The study was conducted at village level in Pabna milkshed areas of Bangladesh to asses the existing feed and fodder sources of cattle. The results showed that the overall number of cattle per farm family was 7.17 and chicken represents highest number (15.57) per farm family in this area. The results also indicated that during monsoon season the bathan is planted with Vigna mungo and Lathyrus sativus and average grazing hours per day varied from 1.1 in October to 5.6 in February. In Summer, they were offered naturally grown Cynodon dactylon with supplementary feeding of rice straw. The study further showed that the highest (65.7%) feed scarcity was found during mid April to mid May followed by mid June. The cultivation of Vigna mungo was highest (76.71%) compared to Lathyrus sativus by the farmers in the bathan areas. The major constraint to cattle production is the scarcity of quality feed during mid October to mid November.

비점오염물질 및 고농도 가축분뇨는 수계 및 습지 수질 악화의 주요 원인으로 보고되고 있으며, 이를 관리하기 위한 방안으로 저영향개발기술 (Low Impact Development, LID)에 대한 관심이 증가하고 있다. 인공습지는 다양한 오염물질 저감 기작을 기반으로 가축 사육 농업지역 내 비점오염원 관리 방안으로 제시되고 있다. 이에 본 연구에서는 전라북도 J시 내 경작지 및 가축 사육 지역을 대상으로 현장 모니터링 및 모델링을 기반으로 인공습지의 적용성 평가를 실시하였다. 연구대상 지역의 강우 시 유량가중평균농도(Event Mean Concentration, EMC) 농도는 건기 시와 비교하여 BOD 기준 약 27배 이상 높은 것으로 나타나 비점오염원 관리가 시급한 지역으로 나타났다. 모델링 기반의 인공습지 저감 효율은 BOD 57.5%, TN 48.9% 그리고 TP 64.2%를 보였다. 하지만, 다량의 강우유출수가 발생하는 시점과 동절기에는 다소 효율이 감소하는 경향을 보여 해당 시기 인공습지 운영에 관리가 필요할 것으로 판단된다. 마지막으로 본 연구 결과는 인공습지가 가축 사육 농업지역 내 안정적인 비점오염원 관리가 가능한 대안으로 제안될 수 있는 것을 보여준다.

Bovine spastic paresis (BSP) is a neuromuscular disorder characterized by hypertension and stiffness of hindlimb. Two Korean native cattle (Hanwoo) calves developed BSP or BSP-like symptoms, and a tenotomy of superficial tendon of medial head and deep tendon of lateral head of gastrocnemius muscle was performed for treatment. A cast was applied postoperatively to prevent muscle rupture and was removed three weeks later. The prognosis was evaluated at 3 weeks, 6 and 18 months postoperatively. Neither calf showed any other postoperative sequelae. This is the first case study to report the diagnosis, treatment, and prognosis of BSP in Hanwoo.

The significance of this study was to analyze the quality value of organic livestock pork for the first time based on the results of managing and testing the cycling organic farming of black pork and vegetables within farm for two years. The results of analysis could be summarized as follows. First, the pork of experimental group with crop-livestock cycling farming showed the excellent quality and high consumer preference compared to the control group of general pork or pork from non-crop-livestock cycling organic farming. In the content ratio of Omega-3 as a representative essential fatty acid, it was 1.46 that was about 2.8 times more than general pork (0.52). In case of Omega-6, it had about 2.5 times more than general pork. Especially, the U/S ratio value which was the content ratio of Unsaturated Fatty Acid (UFA, U) of Saturated Fatty Acid (SFA, S), was largely shown in pork (2.93) from cycling organic farming. Second, it would be necessary to maintain the economies of scope shown in crop-livestock cycling organic farming, and the high quality value of livestock products. For this, there should be a value chain model that could realize the economies of scope and economies of scale at the same time based on scaling and diversification through cooperative organization between farmers. Through this, it would be possible to establish a cycling model called 'community cooperative agriculture' by forming local internal markets through cooperation of production-processing and integration of distribution-sale-consumption. For the managerial activation of this cooperative organization, the government should promote/support the small crop-livestock cycling organic farming cooperative organization in local unit. For securing the reliability of crop-livestock cycling organic agricultural products and crop-livestock cycling organic livestock products, it would be necessary to review the introduction of Participatory Guarantee System (PGS).

Crop-livestock mixed farming systems depend on the efficiency with which nutrients are conserved and recycled. Home-grown forage is used as animal feed and animal excretions are applied to cultivated crop lands as manure. The objective of this study was to develop a mixed farming system model for dairy cattle in Japan. The model consisted of four sub-models: the nutrient requirement model, based on the Japanese Feeding Standards to determine requirements for energy, crude protein, dry matter intake, calcium, phosphorus and vitamin A; the optimum diet formulation model for determining the optimum diets that satisfy nutrient requirements at lowest cost, using linear programming; the herd dynamic model to calculate the numbers of cows in each reproductive cycle; and the whole farm optimization model to evaluate whole farm management from economic and environmental viewpoints and to optimize strategies for the target farm or system. To examine the model' validity, its predictions were compared against best practices for dairy farm management. Sensitivity analyses indicated that higher yielding cows lead to better economic results but higher emvironmental load in dairy cattle systems integrated with forage crop production.

Theoretically, it is said that economies of scope can be realized in the cropelivestock cycling organic farming. Thus, it is also used as the principle of organic farming. However, it is difficult to find the cases of the empirical analysis of it in Korea. In that sense, this study is meaningful in that it analyzed the agricultural data of case farms of obtaining the approval of both organic agricultural products and organic animal products and practicing cycling farming for 4 years and tested the hypothesis. This study measured economies of scope by using the actual measurement value and estimation value farming performance statistics for 4 years of case farms. This farmhouse conducted nutrient cycling in the farm like self-manufacturing and injecting organic agricultural byproduct and wild grass as organic livestock feed and fermenting organic livestock manure to organic compost to return it 100%. The results can be summarized as follows: According to the result of cycling farming of combining and producing organic agriculture and organic livestock, economies of scope were found to be realized in this case farmhouse. That is, although not strong, EOS>0, there were economies of scope. The measurement value appeared as 0.0722, 0.00378, 0.04667 and 0.13127 in 2012, 2013, 2014 and 2015, respectively. It was improved as time passes and the scale gets smaller. Therefore, in order to further improve economies of scope, there should be measures of reducing duplication costs between agriculture-livestock as low as possible and lowering the production cost of organic feed. That is, there is a need for the management strategy to adjust the import function and cost function according to the change in management paradigm and cropping system.
