In recent years, consumers have recognized the issue of and expressed concern over farm animal welfare. Therefore, worldwide, chicken farms are transitioning from traditional caged breeding systems to welfare-oriented breeding systems. In this study, we further analyzed and compared the prevalence and protection rate of various diseases by challenging chickens under conventional and welfare-oriented breeding conditions with low pathogenic avian influenza. Ten chickens were randomly selected from each farm (conventional and welfare) from which Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) were identified and isolated. Additionally, low pathogenic avian influenza (LPAI) were challenged to broilers from each farm and samples were collected from these chickens using oral and cloacal swabs to investigate viral shedding and titer. The results showed that Mycoplasma infection did not significantly differ between breeding systems. Initially, LPAI viral shedding and titer significantly differed between breeding systems post-challenge, but as the experiment progressed, there was ultimately no significant difference.

We conducted investigations of the information and welfare of cattle in Korea. The livestock housing of conventional cattle farms and organic cattle farms were open side wall type with winch curtain and used litter floor. The stocking density of conventional (ranging from $10head/m^2$ to $12.5head/m^2$) and organic cattle farms (ranging from $10head/m^2$ to $16.7head/m^2$) met the demand for conventional or organic standards, respectively. The galvanized plate and sunlight plate were used as the roof material in all of farms. Especially, additional areas were provided to produce forage or to improve animal welfare in organic cattle farms. Thus we believe that present data contribute to develop the animal welfare certification for cattle and to improve animal welfare in Korea.

Broiler chickens are exposed to various stresses throughout their lives, and those stresses affect their well-being and meat quality. Therefore, the farm breeding system is critical for reducing stress in broilers and improving animal welfare. This study was conducted to evaluate the difference between general farms and animal welfare farms and to evaluate feather corticosterone as an index for measuring stress. Samples of 28-day-old broilers (blood, feathers, and muscle) were collected from slaughter-houses, and corticosterone, along with HSP70, glycogen, and L-lactate, were extracted from feathers and serum as indicators of broiler stress levels and energy metabolism. The analysis results confirmed a significantly (p<0.01) higher feather cortisone level in the general farm group than in the welfare farm group, but no significance was detected for serum corticosterone. HSP70 levels did not differ in muscles and feathers. Glycogen levels were significantly higher in the general farm group than in the welfare farm group (p<0.01), but L-lactate levels showed no difference. Our results suggest that feather corticosterone can be used as an indicator to evaluate stress differences between general farms and animal welfare farms and that long-term stress can be assessed.

This study was conducted to investigate the detection rate and serotypes of Salmonella spp. in conventional and welfare poultry farms. Ten welfare (five layer and five broiler) and 15 conventional farms (five layer and ten broiler farms) were visited to collect environmental samples for identification and serotyping of Salmonella spp. The detection rate of Salmonella spp. was higher in the welfare farms than in conventional farms in both layer and broiler farms. In layer farms, Salmonella spp. was detected in 0.76% (1 out of 130) of samples from one of five welfare layer farms, but was not detected in the five in conventional layer farms. No significan ifference (P>0.05) was observed between the welfare and conventional layer farms. In broiler farms, Salmonella spp. was detected in 10.5% (21 out of 200) of samples from four of five welfare broiler farms and 3.5% (7 out of 200) of samples from five of ten conventional broiler farms, and a significant difference (p <0.05) was observed between the welfare and conventional broiler farms. Among 29 Salmonella spp. isolates, five isolates were serotyped to Salmonella enterica subsp. Enteritidis (n=2), Salmonella enterica subsp. Grampian (n=1), Salmonella enterica subsp. Virchow (n=1), and Salmonella enterica subsp. Senftenberg (n=1). These results suggest that microbial risks could be higher in welfare farms than in conventional farms due to easy access to open-air areas, environmental enrichment, and reduced use of antibiotics. Therefore, continuous monitoring and surveillance for Salmonella spp. is necessary to improve the microbiological safety of poultry meat.

This paper aims to identify the characteristics of the tenant farm's income compared with farm household consumption. Farm household surplus is a critical criteria for the reproduction of agriculture. The degree of self sufficiency of farm household consumption according to agricultural income was rapidly decreasing for the period of 1980's. Only 78.9 percents of farm household consumption was earned by agricultural income. Tenant farms were classified according to the following characteristics; self-supported, semi self-supported, leased, deleted, over-consumption. Self-supported tenants are one of the backbones of Korea's future agriculture, because they are able to meet their household needs by only their farm work without other income producing endeavors. The rent paid by those tenants surveyed was estimated at 26.2 percents of their farm household income. However, the national average for such rental payment is equivalent to 4.7 percents of farm household income. 63 percents of paddy rental fee was paid by inkind of rice and 80 percents of the upland rental fee was paid by cash. Self-supported farms as 20 percents of total surveyed should be the target of agricultural price policy and semi self-supported & over-consumption farms as 30 percents be that of rural development policy, and the other half be that of social welfare policy.

The objectives of this study were 1) to evaluate level of satisfaction of the farm helper system which has been executed by Ministry of Agriculture & Forestry from the year 2000 as one of the welfare policies for assisting production activities of woman farmers. and 2) to suggest some measures for improving farm helper system. The data were collected from selected 729 women farmers who utilized the farm helper system. The major findings and suggestions from this study were as follows: 1) Women farmers responded that they had positive attitudes toward utilizing farm helper system by answering 'obtaining mental stability'(34.6%). 'reducing a burden of child birth'(29.2%), 'continuing to work on farm activities'(24.4%) and 'trust in national policies'(10.7%). 2) In addition, women farmers wanted to use the helpers for two months, before and after having a child birth. 3) They suggested that farm helpers system should be extended to other areas such as farming(21.5%), nursing(18.6%), and child-caring(16.1%).

Korea has been striving for the development of the nation in various aspects. It will also have to make an effort for its continued development in the future. The problems of low-income groups that occur in those processes cannot be simply ignored now. It is needed to provide an equal opportunity to low-income groups so that they can be part of the society. The cycle of economic problem should be disconnected through this process. Farm-Housing is one of the solutions to this problem. Its purposes are not only to provide residence in the complex, but to gain income through various activities, such as production, distribution and consumption, and solve part of the economic problems of the people living in the Farm-Housing. To sell the products of Farm-Housing, the neighboring cities need to be designated as a hinterland. For this reason, Farm-Housing needs to be located in the suburban area of large cities. However, the current laws and policies make it difficult to construct Farm-Housing in suburban areas. Presenting plans to solve such problem is the purpose of this paper.

Nine pig farms were evaluated for the welfare quality in Korea using animal- and environment-based parameters (particularly air quality parameters) during the winter of 2013. The Welfare Quality^® (WQ^®) protocol consists of 12 criteria within four principles. The WQ^® protocol classifies farms into four categories ranging from 'excellent' to 'not classified'. Each of these criteria has specific measures for calculating scores. Calculations for the welfare scores were conducted online using the calculation model in the WQ^® protocol. Environment-based parameters like microclimate (i.e., temperature, relative humidity, air speed, and particulate matter), bacteria (total airborne bacteria, airborne total coliform, and airborne total Escherichia coli), concentration of gases (carbon dioxide, ammonia, and hydrogen sulfide) were measured to investigate the relationship between animal- and environment-based parameters. Correlations between the results of animal- and environment-based parameters were estimated using spearman correlation coefficient. The overall assessments found that five out of nine farms were 'acceptable', and four farms were 'enhanced'; no farm was 'not classified'. The average score for the four principles across the nine farms, in decreasing order, were 'good feeding' (63.13 points) > 'good housing' (59.26 points) > 'good health' (33.47 points) > 'appropriate behaviors' (25.48 points). In the result of the environment aspect, the relative humidity of farms 2 (93.4%), 3 (100%), and 9 (98%) was much higher than the recommended maximum relative humidity of 80%, and four out of the nine farms had ammonia concentrations greater than 40 ppm. Ammonia had negative correlations with 'positive social behaviors' and positive emotional states: content, enjoying, sociable, playful, lively, happy and it had positive correlations with negative emotional states: aimless, distressed. The concentration of carbon dioxide had negative correlations with positive emotional states; calm, sociable, playful, happy and it had a positive correlation with negative emotional state; aimless. Our results indicate that the control of the environment for growing pigs can help improve their welfare, particularly via good air quality (carbon dioxide, ammonia, hydrogen sulfide).

Objective: This study carried out base research to build an agricultural safety monitoring system through ICT convergence to reduce safety accidents and enhance welfare in life in the agricultural field. Background: The functions and values of rural villages as the space of living are recognized anew, but occupational accident rate due to farm work accidents is on the rise each year. Therefore, the seriousness of such a problem emerges. The convergence technology combining ICT is recently applied to industries overall, and therefore better services are offered. However, studies on ICT convergence has not yet been applied to the agricultural safety field. Method: This study identified ICT convergence service technology trends and representative serious accident types mainly occurring in agricultural activities. This study defined the major factors of farm work accidents and ICT to solve those accident factors including the sensor technology, wired/wireless communication technology and location information service, and applied them to prototype PCB for the development of an agricultural safety monitoring system. Results: This study proposed an emergency monitoring system for farmers and a harmful environment monitoring system. The ICT technology to prevent farm work accidents can be summarized as sensing technology, ICT and network technology and user interface technology. This study also designed PCB module configuration and situation judgment algorithm as basic research for proposed monitoring system development. Conclusion: The ICT-based agricultural safety monitoring research proposed in this study is expected to become the basis to build a future real time monitoring system, and also is expected to contribute to social safety and welfare service improvement for farmers. Application: The ICT convergence farmer accident prevention system will make contributions to the prevention of serious farm work accidents.
