Researchers have different views on impact of information system use on productivity. The differences are fueled by 'the productivity paradox' insisted by Brynjofsson(1993). This paper intend to quantitate impacts of information system and to test the productivity paradox of using the information system. Restricted Maximumlikelihood Estimation(RMLE) method is applied on data from 81 farms adopting Pigplan system. The results find positive productivity improvement with information systems in swine farm. Adopting Pigplan system increases 0.52 in PSY(pigs per sow per year) and 0.087 in sow turnover. When it comes to region and farm size, region has impact on both PSY and sow turnover, while farm size does not. This result infers that local cooperatives, regardless of farm size, differentiate the impacts of the information system, implying that the ability to utilize information systems should be improved in organizational level.

This study was conducted to examine the effect of HACCP implementation on the cost of medicine use, antibiotic utilization, and productivity of swine in Korea. Data were collected from forty-five swine farms before and after implementation of a HACCP system. The cost of medicine used, the number of different antibiotics used and the number of feeds containing antibiotic supplements added at the feed company tended to be lower (p>0.05) after HACCP implementation. Additionally, the number of feeds containing antibiotics supplemented at the farm was significantly lower after HACCP implementation (p<0.05). Moreover, the number of piglets born per sow per year and pigs marketed per sow per year were higher after HACCP implementation (22.0, 20.0) than before HACCP implementation (20.4, 18.9). These results suggest that implementation of HACCP systems on swine farms may provide beneficial effects such as reduction of medical expenses and improved productivity, as well as increased safety of livestock products for consumers.

This study was conducted to investigate the effects of the type and application level of swine manure on herbage productivity, efficiency of nitrogen utilization and environmental pollution by the leaching of nitrogen compounds in mixed grassland. The field experiment was carried out on established grassland sward growing on silt clay loam soil. Main plots were the types of swine manure, such as swine manure fermented with sawdust(SMFWS), swine manure fermented without sawdust(SMF) and swine slurry(SS), and mineral fertilizer(Urea). Subplots were the application levels of swine manure, such as 100, 200 and 400 kgN/ha, The results obtained were summarized as follows; 1. Herbage productivity, nutritive value and nitrogen yields were the highest with mineral fertilizer and followed by swine slurry(SS), and the lowest with swine manure fermented with sawdust(SMFS). As compared with dry matter(DM) yield by application of mineral fertilizer(100%), the DM percents of SMFWS, SMFS and SS were 90.6, 80,9 and 76.8%, respectively. 2. Organic matter(OM) contents of the soil were increased by the applications of swine manure. OM contents were the high set with SMFS and the lowest with mineral fertilizer. 3. The amounts of nitrate leaching by types and application levels of swine manure were the highest in the end of Aug. and early of Sep. during the seasons and ranged from 10 to 25ppm.

This study was conducted to investigate the effects of the application rate of fermented swine manure and additional mineral fertilizer on productivity and nutritive value of corn(Zea mays L.) for silage. Swine manures used in this study were the compost of swine manure fermented with sawdust(SMFWS) and swine sluny(SS). This study was arranged in split-split plot design. Main plots were the types of swine manure, subplots were the application rate of swine manure, such as 100, 200 and 400kgN/ha, and sub-subplots were the application rate of mineral fertilizer, such as 50 and 100kgNiha. Corn DM(dry matter) and TDN(tota1 digestible nutrient) yields increased as application rate of SMFWS and SS increased. DM and TDN yields in SS treatments were higher than those in SMFWS treatments. The effect of fermented swine manure improved positively as application rate of urea increased. Net energy for lactation(NE1) and TDN content in corn decreased as application rate of SMFWS and SS increased, but crude protein(CP) content increased by the application of SMFWS and SS. NE, and TDN contents in SMFWS treatments were lower than those in SS treatments, but CP content in SMFWS was higher than that in SS. The growth and nutritive value of corn were improved by the application of mineral fertilizer. (Key words : Swine manure, Swine sluury, Compost, Zea may, TDN, Net energy)

Recent public concern about air pollution caused by swine production facilities has forced to develop the methods to reduce and control the swine odors. Swine odors were affected the life of pig farm neighborhoods, swine productivity, pig health, diseases, and human right, safety, sanity as negatively. The first approaches of control of swine odors are the change or improve of the classical management systems, which are manure treatment method, manure storage facility, phase feeding, sex-divided feeding, feeder type, liquid-slurry feeding, environment control of swine building and dust control of indoor swine facility. The methods to control odor emission from manure have to include the diet modification as nutritional basis. In recent, research emphasis has focused on manipulating the swine diet to increase the nutrient utilization of the diet to reduce excretion products and reduction of odors. There are lots of feed additives and pit additives introduced as practical basis for reducing odor emissions. The ozone treatment method is candidate as the good system for reducing swine odor. But this system is still too expensive to practice in present.

As control of swine consumptive disease is the key of success in pig farming business, the effect of Oldenlandidae Herba on prevention of swine diseases as an alternative medicine was investigated in-vivo. As it contains substances such as ${\beta}$-sitisterol, ursolic acid and 3-O-${\beta}$-D-giucoside, it is effective on suppression of colonic tumor in rats and also, is widely used as an preventative medicine of cancer and inflammation in Chinese medicine. In this experiment, sows and piglets on two different farms were treated with Oldenlandidae Herba, and they recoded weaning rate greater than 80%, which were higher than national average 70% (PSY 68%). Meanwhile, neither organ accumulation nor toxicity has been detected on the basis of hematology and serum chemistry. In conclusion, the extracts of Oldenlandidae Herba is expected to be an good alternative medicines for swine productivity.

The objective of this study was to examine the effect of HACCP implementation on the medicine use, antibiotic utilization in each feeding stage and productivity of large scale swine farms (over 5,000 pigs) in Korea. Data were collected from ten swine farms before and after implementation of a HACCP system. Total number of piglets, number of initial weaning piglets, number of weaning piglets, survival rate of piglets, date of weaning piglets, number of piglets per sow per year and price for medicine used per month on HACCP implemented swine farms had a tendency to increase without any significant difference. However, parturition rate, market pig per sow per year, number of antibiotic used and farm number of feeds containing antibiotics at fattening stage added at the swine farm were significantly increased after HACCP implementation (p<0.05). Due to increase in the feed cost recently, production cost for shipment in HACCP system implemented swine farms had increased in this study. In conclusion, our results indicated that the implementation of HACCP system might have many effects including reduction of medical expenses and improvement of productivity of the pig farms.

The aim of this study was to examine the effect of HACCP system implementation on the budget for medicine use, antibiotic utilization, and productivity of swine farms in Korea. Data were collected form thirty swine farms before and after implementation of HACCP system. Parturition rate, total number of piglets, number of initial weaning piglets, number of weaning piglets, survival rate of piglets after weaning, date of weaning piglets, piglet per sow per year, and market piglet per sow per year tended to be higher after HACCP system implementation. In contrast, price for medicine used per month, number of antibiotic used, the farm number of feeds containing antibiotics in each, growing stages added at the feed company, and the farm number of feeds containing antibiotics in each growing stages added at the swine farm were lower after HACCP system implementation. Due to increase in the feed cost recently, production cost for shipment in HACCP system implemented swine farms had increased in this study. In conclusion, our results indicated that the implementation of HACCP system might be effective in reducing medical expenses and improving the productivity.

This study was conducted to investigate the effects of application levels of swine manure fermented with sawdust(SMFS) and degree of the slope on productivity of corn, and nitrogen and organic matter runoff in corn cultivation soil. Main plots were consisted of the degree of slope, such as 0, 5 and 10, and the subplots consisted of application levels of SMFS, such as control, 200kgNha and 400kgNha. Lysimeter was constructed with 0.33m width, 3m length and 0.4m height. Dry matter(DM) yields of corn decreased as the slope increased but there was no significant differences between the degree of the slope. DM yields increased significantly as application levels of SMFS increased (pc0.05). DM yields decreased according to continuous cultivation of corn. Total nitrogen(TN) contents of the whole corn decreased as the slope increased(p<0.05). TN content in SMFS treatments was higher than that of non-SMFS treatment but there was no significantly different between SMFS treatments. TN yields decreased significantly as the slope and the application level of SMFS increased(p<0.05). Nitrogen and organic matter yields in the runoff waters increased as the slope and application levels of SMFS increased. The runoff of nitrogen and organic matter was more affected by the increase of the slope than application levels of SMFS. (Key words : Corn, Runoff, Swine manure, Degree of slope, Lysimeter)
