Animal welfare has been gradually gathering more attention from consumers over time, making it increasingly important to assess the level of stress experienced by livestock. Traditionally, stress has been measured by collecting blood to assess cortisol levels, an action that can be considered distressing for the animal. Therefore, we aimed to explore the feasibility of using hair as an alternative medium to blood for stress assessment. We utilized B/F (blood collected at the farm), B/A (blood collected after transport to the auction), and H/A (hair collected at the auction after blood sampling) from calves at the age of 7-9 months transported from the farm to the auction. Hair underwent a washing and extraction process to utilize hair extracts, while blood was centrifuged to analyze using ELISA. The cortisol concentration in the blood was significantly higher in B/A compared to B/F (p<0.05), confirming that the calves experienced stress during transportation. Additionally, H/A was significantly lower than both B/A and B/F (p<0.0001). These results emphasized that cortisol in hair is not suitable for investigating short-term stress in livestock, as it is with blood. While measuring stress indices using hair may not be appropriate for replacing blood, it is considered a highly suitable practice for animal welfare, and further research in this area should be continued.

Ticks cause economic losses to the deer industry by decreasing the growth and production of the farmed animals. The mediation of ticks affects humans and animals by causing contagious disease both directly and indirectly. Blood from farmed deer from the areas near Jangsu branch was collected for screening of infectious protozoa and rickettsial disease. Seventy deer blood samples were collected from 30 different deer farms located in Jinan, Jangsu and Muju. This blood samples were used for blood slide smear examination and hematological analysis. DNA from these samples was extracted and was used for PCR analysis for detection of gene fragments of Theileria spp, Babesia spp, Anaplasma spp and Ehrlichia spp. In the blood slide smear examination and PCR analysis all samples did not show presence of protozoal and rickettsial diseases. Eight blood samples showed anemia, 1 sample showed iron deficiency and 7 samples showed regenerative anemia. Results for PCR analysis showed 2 samples were positive for T orientalis. All DNA samples were negative for Babesia spp, Anaplasma spp, and Ehrlichia spp.

This study was conducted to identify the location characteristics of infected farms in the areas where livestock diseases were clustered(southern Gyeonggi-do and Chungcheong-do), analyze the probability of disease occurrence in poultry farms, find out the areas corresponding to the conditions, and use them as the basis for prevention of livestock diseases, selection of discriminatory prevention zones, and establishment of prevention strategies and as the basic data for complementary measures. The increase of one poultry farm within a radius of 3-kilometers increases the risk of HPAI infection by 10.9% compared to the previous situation. The increase of 1m in distance from major roads with two lanes or more reduces the probability of HPAI infection by 0.001% compared to the previous situation. If the distance of the poultry farm located with 15 kilometers from a major migratory bird habitat increases by 15 to 30 kilometers, the chance of infection with HPAI is reduced by 46.0%. And if the distance of the same poultry farm increase by more than 30 kilometers, the chances of HPAI infection are reduced by 88.5%. Based on the results of logistic regression, the predicted probability was generated and the actual area of the location condition with 'more than 15 poultry farms within 3km a radius of, within 1km distance from major roads, and within 30km distance from major migratory birds habitat was determined and the infection rate was measured. It is expected that the results of this study will be used as basic data for preparing the data and supplementary measures when the quarantine authorities establish discriminatory quarantine areas and prevention strategies, such as preventive measures for the target areas and farms, or control of vehicles, by identifying the areas where livestock diseases are likely to occur in the region.
Data from a village household dairy survey was compared with technical parameters of three model farms (0.2, 0.4 and 0.8 ha in extent) established by the Mid-country Livestock Development Centre (MLDC). In terms of land size, about 67% of the 250 dairy farmers interviewed corresponded with the MLDC models, but only 33% of the farmers were keeping dairy cattle under conditions comparable to the MLDC models (no regular off-farm income). In the 0.2 ha category, village farmers kept more cows, and in the other two categories the village farmers kept less cows than their MLDC model counterparts. In all three categories, the milk production per cow was higher in the model farms (1540 to 2137 vs. 1464 to 1508 litres/cow/year), and this could be attributed to higher feeding levels of concentrates in the model farms as compared to the village farmers (430 to 761 vs. 233 to 383 kg/cow/year). The amount of milk produced from fodder was higher in the village situation in comparison to the models. In the mid country, dairy production seems to depend on access to fodder resources rather than on the extent of land owned. Except in the 0.8 ha village category, the highest contribution to the total income was made by the dairy component (44 to 60%). With 0.8 ha village farmers, the income contribution from dairy and crops was similar (41%). Income from other livestock was important for the 0.2 ha MLDC model, but for all other categories their contribution to total income ranged from 0 to 10%. Access to fodder resources outside own-farm land is vital for economic dairy production. As such, an in-depth analysis of feed resources available and their accessibility needs to be further investigated.
Livestock wastewater is being discharged without treatment from Hasen's pig farm cluster in WangGoong (WG) area into the Iksan Stream, eventually flowing into the ManGyung (MG) at the upstream junction. Although it is well known that before discharge, wastewater must satisfy the pig slurry discharge standards; because of ongoing remodeling, proper treatment is not being performed. According to public records, wastewater from the WG pig farm cluster is responsible for 3.6% of MG River pollution and 2.0% of the SaeManGuem (SMG) Reservoir pollution. As a result, upstream water treatment quality has become primary concern for development of the SMG project. All physicochemical constituents and pathogenic microbes, such as chemical oxygen demand ($COD_{Cr}$), biochemical oxygen demand ($BOD_5$), total suspended solids (TSS), total nitrogen (TN), total phosphorous (TP), fecal coliforms, Escherichia coli and Salmonella at the effluent of WG Plant (S-1) exceed the effluent standards. This is mainly due to insufficient wastewater treatment: the WG Plant is under renovation to increase water purification efficiency. By comparing the water quality at the S-7 junction, where the the Iksan Stream (pig farms) and the Wanggoong Stream (no pig farms) merge, it is clear that farming facilities and improper treatment can critically affect surrounding water quality. While it is clear throughout this study that the level of all physicochemical parameters and pathogenic microbes along the Stream decreased due to sedimentation, biodegradation and/or dilution. An alarming problem was discovered: the existence of pathogenic microbe count(E coli, Salmonella) in the lagoon wastewater and the stream water. Not only were high concentrations of these pathogens themselves found, but the potential existence of more serious pathogens could rise to more dangerous conditions.

When a farmer buys a tractor, the power size of a tractor is determined by various factors such as farm size, farmer's age, farming type, topographical area of farm. Relationships between tractor selection and these factors were found. Three regression models were developed to analyze the relationship. Those models were an OLS-1 model (based on 567 samples having tractors), an OLS-2 model, and a Tobit model (both based on the 1,941 samples). Regression analysis results showed that farm size and farmer's age affected selection of power size for all models at an 1% significance level. It was also shown that some farming types also had significant relationships with the tractor power size. Upland cultivating farmers and livestock farmers had larger tractors than rice cultivating farmers, while orchard farmers had smaller tractors. As for the topographical area, only middle area had significant difference with plain area. Farmers who had a rice-transplanter or a combine had larger tractors than those who didn't.

With emphasis on environmentally safe and sustainable and economically sound and oriented to consumer, this study intends to assess the consumer's cognition and attitudes for safe food distribution, to investigate the supplying system of the organic farm products, to survey the consumer and life cooperatives dealing with organic farm products, and to draw some implications toward environment- and consumer-oriented agriculture. Related literatures and available documents were reviewed to conceptualize the environmental-and consumer-oriented agriculture and consumer and life cooperatives, to grasp the nationwide status of such alternative agriculture and consumer cooperatives, and investigate the consumers' cognition and attitude. In order to investigate the consumers' needs for organic farm products and to grasp the active consumer and life cooperatives dealing with organic farm products, questionnaire method and non-structured interview were applied. The environment-and consumer-oriented agriculture refers hero to the farming system in which any farm food and other living products giving no harm to human and livestock health and catering the consumers' need. The consumer and life cooperatives is consumer's group buying and selling organic farm products organized in the cooperative system with which any consumer can be affiliated to buy organic farm products safely and reasonably.
Bovine leukosis is one of the important diseases in Korea because of economic losses, and this study was conducted to provide basic information for the control of the disease. A total of 2,104 sera were obtained from 491 farms and examined by commercial kit. In the seroprevalence of farms and heads, 71 farms out of 491 were seropositive (14.5%) and 119 heads were positive (5.7%) out of 2,104. In the areal distribution of seropositiveness, Soseong-myeon showed the highest rate (39.5%, 15/38 farms)and Yeongwon-myeon was the lowest (2.6%, 1/38 farms). By age, positive rate in the below of 1 year old cattle was much less than that in the over of 1 year old, namely, the former was 1.9% (3/161 farms) and the latter 20.6% (68/330 farms). According to the farm size, there was no significant difference among the size. However, the highest rate was shown in the farms having 50-99 heads, 23.2% (13/56 farms).
The present study suggests a concept of resources circulation type agriculture and a concept of a livestock zone related to it and evaluated economical efficiency about a possibility of the resources circulation type livestock zone based on the concept. As a result, when the resources circulation type livestock zone is operated in an area of 1,300ha, it was evaluated that the profit of 11,244 hundred thousand won per year is generated, compared to the conventional agriculture. When light and heat expenses and roughage of Hanwoo production, production of TMR forage as well as income of the energy and composting business of livestock manure at the recycling center were considered in addition to that, it was judged that the present zone development bushiness has enough business feasibility. However, it is necessary that the support regulations, etc. is constructed so that all produced compost byproducts are used at farmhouses and the system related to facility investment assurance and assistance of operating expenses is maintained. It is thought that the complement of a system is also necessary so that energy or power generation expenses can be operated in the same conditions as other new & renewable energy, and the nation's purchase of carbon credits(CDM) is investigated and systemized in the early period, and construction of a revitalization plan of the business through budget securing of the Ministry of Agriculture and Forestry related to the trade of CDM and carbon emission rights is also a business that should be urgently developed. In the future, the change of an outside environment will further promote use of the energy. Also, as people, who don't know agriculture. farm village, increase day by day because of population concentration in a city, an opportunity that can new added value through experience tourism or educational programs utilizing them is increasing. Accordingly, if programs utilizing social characteristics, such as utilization as a space of tourism. leisure. experience, system construction of bio-energy and system construction that Micro Grid or Smart Grid as a dispersed storage and generation system is stabilized, are constructed, it can be said that revitalization or success conditions of the zone is further achieved.

The city is developing into a smart city. Smart villages and smart farms are developing in rural areas. Architectural technology needs synergy with smart cities, smart villages, and smart factories (intelligent factories) to help architectural experts understand smart farms and build facilities and equipment. Smart farms require design and construction technology with architectural structure and function. The purpose of this study was to investigate the current status and cases of smart farms in Korea and to investigate cases abroad. The conclusion is as follows. ① Smart farms are developing rapidly. The Korean government is expanding smart farms by utilizing ICT technology and infrastructure. ② 'Smart Farm Innovation Valley', which has been promoted since 2018, is a cutting-edge convergence cluster industrial complex that integrates production, education, and research functions such as start-ups and technological innovation. ③ In domestic cases, smart farms are operated in subway stations, buildings, supermarkets, and restaurants. ④ In the Japanese case, a dome-type smart farm was being operated. It utilized factory wastewater, waste heat, renewable energy, and used new materials. Otemachi Ranch raised livestock and provided a lounge on the 13th floor of the building. ⑤ In the cases of Korea and Japan, the smart farm technology is very similar. As stated earlier, since the food culture and agricultural technology of both countries are similar, we hope to promote the development of smart farms that can reduce concerns about future food by communicating and sharing mutual technologies.
