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.

본 연구는 가축분뇨의 처리형태별 시용수준에 따른 목초의 생산성과 질소의 이용효율 및 질소의 용탈에 의한 환경오염에 미치는 영향을 파악하기 위하여 화학비료, 톱밥발효돈분, 무톱밥발효돈분 및 액상발효돈분을 100, 200, 400kgN/ha 수준으로 시용했을 때의 연구 결과는 다음과 같다. 1. 화학비료와 분뇨의 처리형태별 목초의 생산성과 사료가치 및 N 생산량에 미치는 시용효과는 화학비료 ＞ 액상발효돈분 ＞ 무톱밥발효돈분 ＞ 톱밥발효돈분의 순이었다(건물수량 : 화학 비료(100), 액상발효돈분(90.6), 무톱밥발효돈분(80.9), 톱밥발효돈분(76.8)). 2. 토양 유기물 함량에 미치는 영향은 화학비료 ＜ 액상발효돈분 ＜ 무톱밥발효돈분 ＜ 톱밥발효돈분의 순이었다. 3. 가축분뇨의 처리형태나 시용수준에 따른 NO$_3$의 용탈은 시기적으로는 8월하순 9월초순에 가장 높았으며 N시용수준 400kg/ha 수준까지에서도 서로간에 차이는 매우 적었고 NO$_3$함량도 결코 25ppm을 초과하지 않았다.

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.

본 연구는 국내 대규모 양돈농장에 HACCP 시스템을 적용 후 나타나는 생산성 및 안전성의 지표인 분만율, 총 산자수, 초기 포유개시 두수, 이유 두수, 이유후 육성율, 이유일령, 모돈두당 연간 비육돈 출하두수와 월평균 약제비, 농장에서의 사용항생제수 사육구간별 사료내 항생제 첨가 농가수-사료공장에서 첨가, 사육구간별 사료내 항생제 첨가 농가수-농장에서 첨가 등을 조사하여 그 효과를 검토하고 이를 향후 수행할 농장 HACCP 연구 관련 기초 자료로 사용하기 위한 목적으로 실시하였다. 분만율은 HACCP 적용 전에 비하여 적용 후 유의적으로 증가하는 것으로 조사되었다(p<0.05). 모돈 두당 연간 규격돈 출하두수도 HACCP 적용 전 17.99두였으나 적용 후 18.83두로 유의적으로 증가하였다(p<0.05). 농장에서의 사용항생제수는 적용 전 8.88개에서 적용 후 6.13개로 약 25.97%가 유의적으로 감소하였다(p<0.05). 특히 사육구간별 항생제 첨가농장수-농장에서 첨가는 비육구간에서 HACCP 적용 전에는 전체 10개 농장 중 4개 농장이 해당되었으나 적용 후에는 모든 농장에서 항생제를 사료에 첨가하지 않는 것으로 나타났다. 따라서 본 연구결과에 의하면 대규모 양돈농장에 HACCP 시스템을 적용할 경우 동물용 의약품 사용 감소와 함께 농장의 생산성에도 좋은 효과가 있을 것으로 판단되며 동시에 소비자에게 더욱 안전한 축산물을 제공할 수 있을 것으로 판단된다.

본 연구는 양돈 사육규모가 2,000두 이상 5,000두 이하인 국내 중규모 농장의 HACCP 시스템 적용 전 후의 항생제를 비롯한 동물용의약품의 사용 현황 및 생산성에 미치는 영향을 조사하고 이를 차후 수행될 농장 HACCP 연구의 기초자료로 활용코자 실시하였다. 본 연구에 선정된 HACCP 적용 양돈장의 평균 노동인력은 내 외국인 모두 6.55명으로 조사되었으며, 구간별 평균 사육 구성 비율은 모돈 11.23%, 자돈 38.37%, 육성-비육 50.40%로 조사되었다. 농장의 생산성지표인 분만율, 총산자수, 포유 개시두수, 평균 이유두수, 평균 이유기간, 모돈 두당 연간 이유 두수, 모돈 두당 연간 규격돈 출하 두수 등은 HACCP 시스템 적용 전에 비하여 적용후 증가하는 경향을 나타내었다. 출하두당 생산비와 사료비도 HACCP 시스템 적용 전에 비하여 적용 후 증가하였으나 이는 조사 당시 국제 곡물가격의 영향에 기인한 것으로 판단된다. 월평균 약제비와 사용항생제수는 HACCP 적용 전에 비하여 적용 후 각각 -13.27, -27.50% 감소하는 것으로 나타났다. 사육구간별 항생제 첨가농장수-사료공장에서 첨가와 사육구간별 항생제 첨가농장수-농장에서 첨가는 HACCP 적용 전 많은 농장에서 항생제가 첨가된 사료를 급여하였으나 적용 후에는 사용율이 평균 59% 감소하였으며, 특히 육성 및 비육구간에 사용되었던 항생제 첨가사료가 상당히 감소되는 경향을 보여 주었다.

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)
