Survey of mastitis management and incidence of mastitis in the Gyeongnam was started in May to September 2009 to solve mastitis problem statistically valid data for use in estimating mastitis management, isolation and antimicrobial drug susceptibility in 30 dairy farms having over 350,000/ml somatic cell count. In investigation on recognition of farmer about bovine mastitis, the ratio of understanding of differences between infectious and environmental origin, understanding of correlation between superbacteria and using indiscriminate, necessity of pathogen identification, and necessity of antimicrobial sensitivity tests were 80.0%, 73.3%, 33.3%, and 53.3%, respectively. In survey of mastitis management type, regular california mastitis test (CMT), conducting CMT test and empirical self-treatment, when detecting suspected cows, were 30.0%, 40.0%, and 46.7%, respectively. Checking and cleaning pulsators biweekly, cleaning vacuum system and replacing liners every 3~6 month, and getting milking system checked by engineers showed 80.0%, 76.7%, and 76.7% in the questionnaires, respectively. In recognition of farmer about milking hygiene for prevention of bovine mastitis, using individual towels, separated milking (milking order of cows), and teat-dipping disinfection after milking exhibited 13.3%, 86.7%, and 93.3%, respectively. In conclusion, through the questionnaires and laboratory test, we suggest that recognition of farmer about management and incidence of mastitis was very low, thus systemic educational program and public relations about mastitis management were need for dairy farmers.

The actual condition of farmstead, mainly livestock facility, was surveyed in ChungChongBukDo in order to find out factors and problems of farmstead planning design. From the data collected, a type, plot, size and scope of farmstead, relationship of house and farmstead, topography, climate, proprietor's opinion on them were analyzed or obtained as the basic design criteria for planning: designs. The best type of farmsteads was individual farm having livestock facilities. They were mostly breeding a kind of livestock without their plan and Bone planning at residing area. The south aspect of the facility was extremely much and slope of the land was mostly 15。 below. Wind blows from East-South in summer and winter wind are West-North extremely much. Sun heat was mostly above 6 hours. In the case of collective and composite farmstead, proprietors wanted that a head of cow has 1,000-3,000 pyeong, the area of facility has 1,500-2,000 pyeong, total area of farmstead has 45,000-400,000 pyeong and an estimated expense is 0.2 - 1.5 billion won. Farmstead planning design was proposed through field survey results and contents of'references. Examples of farmstead planning design were composite and concentrated type and existed according to the situation of road(North, South, East, and West).

Digital photographs of 16 pork chops were each modified to give 16 treatments, such as two levels each of fat cover, color, marbling and drip, giving a total of 256 images. Consumers from three locations in France and six locations in Korea selected their preferred chop from 16 treatments in different chops and repeated this selection process eight times from different groups of chops, respectively. Respondents were asked to complete a questionnaire on socio-demographic information. Both the results of the French and Korean surveys gave four clusters of consumers, but they were not the same in terms of the choice strategies used, or in terms of their relationships with the socio-demographic items. The interesting apparent similarities (such as, both color levels being equally important to consumers in both countries) and differences(such as, the strong preference for lean meat in France; no fat preference in Korea) suggest a need to compare the results from the two countries. However, due to the difference of the socio-demographic make-up of the consumer panels from the two countries, a simple and direct comparison of the clusters based on choice and their relationships with the questionnaire items is not possible, but is currently being explored.

Respiratory diseases are common in swine industry and have great economic importance. Respiratory disorders cause substantial losses to the swine industry. Losses associated with respiratory disease vary considerably between herds and seasons. In a survey was carry out to investigate the lesion of red internal organs in slaughtered pigs and provided assistant data which are useful for each farm. From november 2012 to december 2013, 1,680 pigs out of 84 farms were sampled in Jeonbuk province. Gross lesions such as swine enzootic pneumonia (SEP), pleuritis, pleuropneumonia, pericarditis, liver milk spot were examined for the pigs. Overall prevalence of SEP was 55.7%. According to season, the incidence occurred higher in fall than winter, spring, and summer. The mean SEP score was 0.91, the highest incidence occurred in fall. The prevalence of pleuropneumonia, pleuritis, pericarditis, and milk spot was 36.4%, 49.7%, 2.3%, and 8.8%, respectively. The positive rate of PRRS and PCV2 was 2.9% and 70.0% by PCR analysis.

The purpose of this study was to investigate crucial factors on HACCP system implementation in domestic livestock product plants, and to offer job satisfaction and the career prospect of HACCP system operators. The survey was carried out by selecting 150 HACCP system operators who implemented HACCP system. The respondents claimed that the most important contents in HACCP system operation were to assemble HACCP team (21.8%), and the second was to monitoring (20.0%). Documentation and recording (16.9%) and verification (11.1%) were followed. The respondents answered the major factor in sanitation management was cleaning/washing/disinfection (18.9%) and inspection (18.4%). The results showed that there were significant differences in the prospect of occupation in HACCP system operator by the gender (p < 0.015), age, livestock product facilities, service period, and position (p < 0.001). The respondents from HACCP system operator were satisfied with their job (73%) and also showed optimistic prospect of occupation (82%).

This study was attempted to survey on the prevalence of canine heartworm(Dirofilaria immitis) infection among 100 dogs(male 39, female 61) on the nine breeding farms in eastern Chungnam province in December 2002. Blood samples taken from dogs were examined for the presence of D immitis microfilaria by the modified Knott's test and an antigen test was using FASTest$\^$/ HW Antigne kit (Mega Cor A-6912 Horbranz-Austraia). 1. Eleven(11.0%) of the 100 examined dogs were microfilaria positive, while nineteen dogs(19.0%) were antigen positive, which suggested that the antigen test was more sensitive than the microfilarial test in detecting heartworm infection. 2. Infected dogs were observed higher more at 2 years older ages(4/48, 8.3%) and male(9/39, 23.1%) than young ages(4/48, 8.3%) and female(10/61, 16.4%). 3. The regional infection rates were of Gongju(15/43, 34.9%), Geumsan(4.27, 14.8%), while none of infection dogs in Yeongi(0/30, 0%). 4. Survey for hematological values of D immitis infected dogs : WBC and eosinophils were 21.4${\pm}$7.2 k/${\mu}\ell$, 3.5${\pm}$0.4 k/${\mu}\ell$, respectively. In conculsion, this study could be overemphasized the importance of control program the heartworm in eastern Chungnam province

This study was carried out to investigate the status of hoof diseases and to develope treatment method for cattle with hoof diseases during the period of January to December in 2000. Out of 435 heads, 34 heads(7.8%) had hoof diseases. In respect to season, incidence rate was higher in August to September than that of other seasons. The incidence rates of hoof rot, pododermatitis verrucosae, laminitis, other cases and trauma were 14 cases(41％), 10 cases (29%), 7 cases(21%), 2 cases(6%) and 1 case(3％), respectively. In respect to age and milk production, Incidence rate was higher in the cattle with high milk production. Incidence rate of hoof diseases on the hind-limbs was higher than that of the fore-limbs. E. coli(8 strains), Clostridium spp(8 strains), Staphylococcus spp(6 strains), Fusobacterium spp(6 strains), and Bacteroides spp(6 strains) were isolated from the hoof lesions. All isolates were sensitive to composite preparation made of mainly formalin with picric acid and phenol. (Treatment against each strains isolated was sensitive to composite preparation made out of the main constitutions of formalin with picric acid and phenol).
