In this research pig house facilities what are 3,029 houses hold over 1000 heads were surveyed by scale and province. Full-time farms hold over 1000 heads breed total 7,229,892 heads. And farms breed 2,386.9 heads averagely. Pig houses were constructed august 1995 averagely. Each of houses have $3,017.2\;m^2$ scale. The construction type of pig house was winch-curtain type 77.2% which was most popular, confined type 51.3%, litter type 7.4% and loft type 4.6%. The winch-curtain type was popular than windowless type in pig farms which have 1,000-1,999 heads. But pig house construction type which have more than over 10,000 heads was windowless type more than winch-curtain type. Manure removing type was slurry 72.3% and scraper 38.5% in farms which have 1,000-1,999 heads. Manure removing type was slurry 83.3% in farms which have over 10,000 heads. Proportion of roof type of pig house was slate 51.2%, panel 46.1%. But in middle or small farms, slate type was only 25.0%. Proportion of wall type of pig house was 41.9%, block 21.9%, concrete 7.6%, winch-curtain 6.3%, and bnck 5.9%. Ventilation type of pig house was natural winch 46.1%, mechanical windowless 69.8% and mixed type 53.1%. So, mechanical windowless type was popular than natural winch type. Especially the farm scale is bigger the mechanical widowless type was more. Utilization period of pig house was 8.1 years about automatic feeder, 8.3 years about waterer, 8.2 years about electric facilities and 9.0 years about floor material. Thus, almost of facilities were used at least 8 years.

This study was conducted to evaluate animal welfare approved farms in three housing systems (open, windowless, and free-range). The survey was conducted in 25 animal welfare approved farms, and 10 farms were surveyed for distribution status. The main breed in all animal welfare approved farms of laying hens was Hy-Line Brown variety. In the case of open house, laying hens were bred in traditional and panel houses simultaneously; however, the ratio of panel house was 58.3%, which was higher than that of the traditional house. All the windowless houses were made of panels and more than 15,000 laying hens were housed in a single windowless house. In the case of free-range house, it was maintained on a small scale of less than 12,000 birds. Fifty-six percent of the surveyed farms were breeding at $7{\sim}8birds/m^2$. In terms of male and female ratios, most farms maintained 1 male:15 females, but there was a farmhouse that switched 17 or 20 females to 1 male. The daily dietary allowance was 110~170 g, and 32% of the surveyed farms provided feed of more than 150 g/day, which showed that forage feed was important. The age of at the first egg was 123 days, 122 days, and 120 days, and the peak percent was 91.8%, 94.9%, and 86.5% in open, windowless and free-range houses, respectively. The average egg production rate was 74.0%, 84.6%, and 72.7% in open, windowless, and free-range houses respectively, thus, there was no correlation between feed intake and hen-housed eggs. Distribution of welfare certified eggs was mainly a direct deal with the consumer or through contract production. The ratio of direct transactions between large-scale marts and eco-friendly specialty stores of welfare approved eggs was higher than that of conventional eggs. The rate of contract sales of eggs in both the barn and free-range systems was high, and the percentage of courier sales farms was also high. Excluding courier services, price of eggs in the barn system rose to more than 30 won/egg in the second half of 2017 (after AI). Price of eggs in the free-range system rose to more than 50 won/egg in the second half of 2017 (after AI). In the case of courier sales, the same price of 500 won was maintained before and after AI. In conclusion, the results of this study can be used as basic data for improving the animal welfare certification system for laying hens in Korea.

The current study was performed to clarify the pupation disorder symptoms in silkworm which herbicide, molinate has been regarded as a causal origin. Molinate residues in mulberry leaves was monitored in major rearing area of silkworm; Yeacheon, Sangju and Namwon. Detected range of the molinate in mulberry leaves was 0.002 to 0.013 mg/kg and detection frequency was 30.0 to 81.8%. Molinate concentration in the air of mulberry tree growing area was $0.004\;{\mu}g/m^3$. Water diluted solution of molinate at the concentration of 1, 10, 100 mg/l gave no abnormal symptoms in silkworm irrespective of spraying to silkworm or spiking to diet. Exposing the silkworm to the air containing 250, 2,500, and $10,000\;{\mu}g/m^3$ also revealed no abnormal symptom. These results illustrated that the abnormal growth of silkworm encountered in the field was not caused by pesticide contamination.

브로일러를 생산하는데 있어서 환기가 매우 중요한 요인의 하나가 되는 것은 말 할 필요도 없다. 그러나 브로일러 농장의 실태를 볼 때 환기조작이 적절하지 않은 예가 있는 것으로 보인다. 중요한 것은 기상조건의 변화를 예측해 보는 것이 필요한데 이는 환기가 브로일러의 발육과 건강을 위해 이상적인 환경을 만들어 내는데 중요하기 때문이다. 사내환경이 부적절 할 때 브로일러의 발육저하가 발생되며 성장률도 나빠지고 사료효율도 저하된다. 또 깃털상태도 좋지 않아 상품의 질이 떨어져 결국 수익저하로 이어진다. 현재 국내에서 사용하고 있는 브로일러 계사는 환기가 좋지않은 경우가 많이 보이는데 커텐을 사용할 때 자연환기를 이용하는 계사에서는 주의깊은 점검을 필요로 하고 결국은 보다 안정된 환경을 공급해 주는 것이 필요하다. 현재 양계장에서 활용하고 있는 강제환기법은 기본적으로 팬을 이용해 계사내의 공기유동을 조정하는 것으로 되어 있으나 강제환기에는 계사내에 공기를 끌어들이는 방식과 계사내의 공기를 외부로 배출시켜 나가는 방식이 있다.

우리나라의 축산업은 대략 1970년대 이후부터 급속한 산업화에 따른 인구 증가 및 국민 소득의 증가로 식품 소비 형태가 변화하면서 육류 및 유제품의 소비가 증가하게 되고 농가에서 새로운 소득원으로 축산업이 활성화되면서 전통적인 재래식 가축사육 형태에서 전업식 사육형태로 점차적으로 규모가 커지기 시작하였다. 반면, 우루과이라운드(UR) 협상에 따라 농산물을 비롯한 축산물 등 완전시장개방에 따라 국제경쟁력 약화 및 축산폐수 규제의 강화에 대한 우려 등으로 겸엽(兼業)농식의 축산업은 도태 감소하게 되고 그 규모에 있어서 전업 전문화, 대규모화로 변모되어 가고 있는 추세임은 분명하다. 따라서 축산물 시장개방에 효율적으로 대처하기 위해서는 축산전업농가 육성과 계열화와 그에 따른 고품질 축산물 생산을 통한 축산업 경쟁력 제고에 노력해야 하며 아울러 축산폐수처리에 대한 기술개발 및 연구투자 확대와 더불어 축분 유기질비료의 생산 및 유통을 촉진하기 위한 법적 근거를 마련 등을 추진함으로서 국내 축산업의 경쟁력을 유지하며 친 환경적인 축산 경영을 이루어야 할 것이다. 이에 본 연구에서는 현재 날로 심각해지는 가축분뇨가 환경에 미치는 영향을 평가가 필요하여, 기초데이터의 확충 및 현황 파악을 위하여 축산 농가 내의 분뇨처리 실태를 조사 하고 문제점을 도출하고자 하였다. 또한 현재 조사된 자료를 바탕으로 가축 분뇨에 의한 오염 발생여부 및 발생량을 예측하고, 가축분뇨에 의한 오염 방지 및 수계에 미치는 영향을 안정적으로 유지하기 위하여 가축분뇨 이용 및 관리를 전반적으로 검토함으로써 가축분뇨를 효율적으로 관리하고 앞으로의 이용에 관한 여러 대안을 제시하는 것을 목적으로 한다.요했던 출혈(2예), 흉골 지연봉합(2예), 급성 신부전(2예), 폐렴(1예), 대동맥내 풍선펌프로 인한 혈전색전증(1예),수술 후 섬망(2예) 등이 있었다. 생존한 10명의 환자들 중 1명을 제외한 나머지 9명의 환자에서 $38{\pm}40$개월간의 추적관찰이 되었는데, 추적 관찰 기간 중에 3명이 사망하였고 생존한 6명의 환자는 모두 양호한 상태(NYHA 기능등급, $I{\sim}II$)를 보였으며, 그 중 3명에서는 혈역학적으로 큰 의미가 없는 잔여단락이 있었다. 결론: 급성 심근경색증 후 심실중격 결손은 수술위험도가 높은 질환이지만, 수술 전 대동맥내 풍선펌프를 삽입하고 조기에 심실중격 결손부의 infarct exclusion 술식과 함께 관상동맥우회술을 시행함으로써 만족할 만한 수술 및 중기 결과를 얻을 수 있었다.출물 투여로 저하되었으나 NC군보다는 높게 나타났다. 간 중 중성지질 함량은 참나물 에탄올 추출물 투여 용량에 따른 유의차가 없었으나, 총콜레스테롤 함량은 고용량 병합투여한 HC-PBH군만 유의하게 저하되었다. 혈청 및 간 중의 지질 함량 변화는 정상식이를 급여한 NC군과 NC-PB군 간에는 유의차가 없었다. 따라서 고콜레스테롤식이를 급여하면서 참나물 에탄올 추출물을 병합투여 시에만 지질대사 개선 효과가 있는 것으로 여겨지며, 고용량 병합투여 시 효능이 더 큰 것으로 나타났다. 고콜레스테롤식이로 인한 산화적 스트레스가 고콜레스테롤혈증을 유발하였으며, 이는 참나물 에탄올 추출물에 함유된 항산화물질을 포함한 여러 생리활성물질이 영향을 미친 것으로 사료된다. 이상의 실험 결과에서 참나물 에탄올 추출물은 고콜레스테롤식이
