The fourth industrial revolution based on information and communication technology (ICT) becomes the center of society, and the overall industrial structure is also changing significantly. ICT refers to the hardware of information devices and the software technologies required for the operation and information management of these devices, and any means of collecting, producing, processing, preserving, communicating and utilizing them. ICT is integrated into industries and services or combined with new technologies in various fields such as robotics and nanotechnology to connect all products and services to the network. The development of ICT, which continuously creates new products and services, has spread to all sectors of the industry, affecting not only daily life but also the livestock sector recently. In agriculture, ICT technology can reduce production costs by efficiently managing labor and energy because it can improve quality and yield based on data on environmental and growth information such as temperature, humidity, light and soil. In particular, smart livestock is considered suitable for achieving livestock management goals because it can reduce labor force and improve productivity by remotely and automatically managing accurate information necessary for raising and breeding livestock with ICT devices. The purpose of this study is to propose the need for ICT technology by comparing farm productivity before and after ICT is introduced. The method of the study is to compare the productivity before and after the introduction of ICT in Korean beef farms, pig farms, and poultry farms. The effectiveness of the study proved the excellence of ICT technology through the production results before ICT introduction and the productivity improvement case of livestock farms that efficiently operated manpower management and reduced labor force after ICT introduction. The conclusion of this paper is to present the need for smart livestock through ICT adoption through case study results.

본 연구는 한우, 젖소, 돼지, 산란계 HACCP 적용 농장의 분변, 원유 및 사육환경에서 병원성세균 등 분석을 통하여 HACCP 적용 농장의 생물학적 위해 관리 실태를 파악하고자 하고 이를 농장 HACCP 시스템 적용에 관한 기초 연구 자료로 사용하는 것을 목적으로 하였다. 미생물 시료는 HACCP을 적용 중인 한우, 젖소, 돼지, 산란계농장의 축사바닥분뇨, 퇴비사, 원유탱크, 집란기, 분변 벨트 등에서 채취 하였으며 축산식품의 생물학적 위해인 Pathogenic E. coli, Salmonella spp. S. aureus 등을 분석하였다. 각 축종별 대장균은 분변에서 100% 검출되었으나 Salmonella spp.는 검출되지 않았다. 또한 젖소농장의 원유 냉각기에서도 S. aurues가 검출되지 않았다. 그러나 돼지농장의 돈사바닥 및 퇴비장에서는 검사건수 30건당 각각 2건, 1건의 Salmonella spp.가 검출되었다. 마찬가지로 산란계농장의 계사바닥 및 분변벨트에서도 전체분석 건수 대비 10~20%의 Salmonella spp.가 검출되었다. 이러한 결과는 문헌상 보고되고 있는 일반축산농가의 병원성세균 관리실태와 간접 비교하였을 경우 HACCP 시스템을 적용중인 축산농가에서의 일반축산농가보다 병원성 세균관리가 더욱 철저히 이루어지고 있는 것으로 판단된다.

With the commercialization and full-timeization of the livestock industry, civil complaints continue to increase, and the livestock industry is facing a crisis due to social problems such as odor caused by livestock manure, soil pollution, water pollution, and environmental pollution. In order to increase productivity in livestock farms, the amount of livestock manure generated is increasing due to excessive use of protein feed and high-density breeding environment, and complaints such as odor and water pollution due to management problems are increasing rapidly. Livestock odor has emerged as a serious social problem, and due to growing complaints, conflicts between the Ministry of Agriculture and Forestry and the Ministry of Environment are even causing the livestock industry to lower its status. There is an urgent need for solutions to identify problems in the livestock industry and improve policies. This study aims to develop a " Abelmoschus Manihot Jinhuakui " brand that can improve the intestinal environment of livestock, reduce odors caused by livestock excrement, and improve the productivity of livestock farms in order to improve the increasingly serious odor problem in livestock sites. For Jeju livestock farms, which place more importance on the environment by securing tourists, eco-friendly feed additives were applied to the experiment, the results were derived, and the focus was on solving fundamental problems of odor generation through the development and packaging of feed additive brands. We aim to fundamentally solve the odor problem of domestic livestock farms, secure eco-friendly livestock farms, and contribute to reducing livestock odors and increasing productivity through research results that reduce ammonia levels in each livestock farm.

This study exploded the correlation between feed and livestock manure characteristics across different livestock species. The selected farms included laying hen, fattening pig, and Hanwoo farms, with visits conducted to each farm at 1-day intervals. In the experiment, feed was provided to each livestock species every day at the same scheduled time, and samples of both feed and livestock manure were collected from each farm after 1 month. The correlation analysis revealed no significant effect on the crude protein content of the feed for each livestock species and the respective livestock manure characteristics. This could be attributed to the fact that the difference in nitrogen content of each feed did not have a substantial effect on the content of the livestock manure components or the differences in individual components were similar. Based on these results, it is crucial to conduct environmental impact assessments on farms using diverse feeding management approaches for each farm.

Assessment of nutrient balance in region unit is important to make a decision on nutrient management in agriculture. In this study, the nutrient demand in arable land and nutrient supply from livestock manure and chemical fertilizer were estimated from pig-concentrated areas. Three regions (H, I and J) were selected on the basis of pig numbers per unit area of arable land. In H and I regions, nitrogen amount from pig manure occupied about 50% of total livestock manure. Nutrient supply was three times higher compared to the nutrient demand in each of 3 regions. Soil available phosphate of higher pig-populated area in regional unit was higher than less populated livestock area. Therefore, livestock manure-derived regional management and monitoring of soil nutrient contents is necessary for the minimization and improvement of nutrient surplus.
