This excrement was conducted to investigate the nuisance of swine excrement. And excrements were collected from 27 heads of swine Euseong swine breeding center and Hongdo-dong swine farm and amounts of faces and urine, nitrogen, phosphorus, and kalium contents and number of parasite were investigated, and for the purpose to clean of excrementing matter, ferment substance and moist soil added to swine excreting matter and floating matter. Heat decresement amount and biological oxygen demand were investigated. And the result obtained were as follows. 1) Average amount of daily excreting faces per swine was 500-2700g from Euseong swine breeding center and 450-2500g from Hongdo-dong swine farm and a mount of excreting urine was 450-4500g from both of farms. The rate of excrements between faeces and urine was 1:1 2) Nitrogen contents were 0.802 ppm in urine and 0.514 ppm in faces, phosphorus were 2.261 % in urine and 0.073% in faeces and kalium contents were 1.094% in and 6.0467% in faeces. 3) Strongyloides ransomi and intestinal modular worm eggs showed the highest of eggs number was the result of observation in parasites, and ascaris showed the next it, whip worm and lung worm showed the lowest. 4) The effect ferment substance additive, amount of dry matter, floating matter, heat decreasement amount and biological oxygen demand was decreased but not significant was appeared. And the effect of moist soil additive, it was more effective that fermented substance additive for the fermentation of swine excrement. 돈분뇨(豚糞尿)의 공해(公害)를 조사(調査)하기 위(爲)하여 유성종축장(儒城種畜場) 홍도동양돈장(弘道洞養豚場)에서 사육(飼育)되고 있는 모돈(牡豚) 27두(頭)를 가지고 분뇨량(糞尿量), 질소(窒素), 인산(燐酸) 가리(加理) 함량(含量) 기생(寄生) 충란(蟲卵), 검사등(檢事等)을 실시(實施)하였으며 돈사오수(豚舍汚水)의 정화(淨化)를 목적(目的)으로 돈분(豚糞)에 발효제(醱酵齊) 오니등(汚泥等)을 첨가(添加)하고 정유물(淨游物), 증발잔유물(蒸發殘留物), 열감작량, B.O.D 등(等)을 검정(檢定)한 결과(結果) 다음과 같은 결과(結果)를 얻었다. 1) 분뇨량(糞尿量)은 1일평균(日平均) 유성종축장(儒城種畜場)이 최고(最高) 2700g, 최저(最低) 500g 이었고 홍도동양돈장(弘道洞養豚場)이 최고(最高) 4500g, 최저(最低) 450g으로서 분뇨비(糞尿比)는 1 : 1이었다. 2) 질소(窒素), 인산(燐酸) 가리(加理)를 분석(分析)한 결과(結果) 질소(窒素)는 분(糞)이 0.514 ppm, 뇨(尿)가 0.802 ppm, 인산(燐酸)은 분(糞)이 0.0739%, 뇨(尿)가 2.261%, 가리(加里)는 분(糞)이 0.0967%, 뇨(尿)가 1.094%이였다. 3) 분(糞)의 기생충란(寄生蟲卵)을 조사(檢査)한 결과(結果) 돈폐충(豚肺蟲) 및 장결절충란(腸結節蟲卵)이 가장 많고 회충(蛔蟲)이 다음이며 편충(鞭蟲)과 간충란(桿蟲卵)이 가장 적었다. 4) 발효제(醱酵齊)의 첨가효과(添加效果)는 무처리(無處理)에 비(比)하여 건조잔유물(乾燥殘留物), 부유물(浮留物), 열감작량, B.O.D 등(等)의 감량(減量)이 나타났으나 현저하지 못하였고 오니(汚泥)를 첨가(添加)할때의 분해효과(分解效果)는 발효제(醱酵齊)에 비(比)하여 상승(上昇) 되었다.

전창기,Jeon, C.G. 충남대학교 농업과학연구소 1976 Korean Journal of Agricultural Science Vol.3 No.1

가토(家兎)의 과배란유기(過排卵誘起)에 있어 P.M.S. 처리(處理)에 의(依)한 Estrogen의 병용효과(倂用效果)를 시험(試驗)하기 위(爲)해, P.M.S. 40I.U를 5일간(日間) 처리(處理)한것과, P.M.S.G. 40IU를 5일간(日間) 처리(處理)하고 최종일(最終日)에 Estrogen 0.1~0.5mg을 병용주사(倂用注射)한 것의 난소소견(卵巢所見)을 비교(比校)하며 배란수(排卵數)를 계측(計測)한 결과(結果), 다음과 같이 그 결과(結果)를 요약(要約)하였다. 1. P.M.S. 40IU를 5일간(日間) 피하주사(皮下注射)하여 24시간(時間) 및 48시간후(時間後)에 교미자극(交尾刺戟)을 준 대조구(對照區)의 평균(平均) 배란수(排卵數)는 21.3~24.1개(個), 과배란(過排卵) 양성률(陽性率) 50~63%에 비(比)하여 P.M.S.G 40, IU를 주사(注射)하고 최종일(最終日)에 Estrogen 0.1~0.5mg을 병용처리(倂用處理)한 구(區)의 평균(平均) 배란수(排卵數)는 32.5~37.8개과배란(個過排卵) 양성률(陽性率)은 87.5~100%로서 Estrogen을 병용처리(倂用處理)한 것이 배란수(排卵數)가 높아지는 경향(傾向)을 나타냈으며 미피열배란수(未破裂排卵數)는 대조구(對照區)가 많은 반면(反面), Estrogen 병용구(倂用區)는 적은 경향(傾向)을 나타냈다. 2. 대조구(對照區)와 Estrogen 병용구(倂用區)에 대(對)하여 난포(卵胞)를 1.0~1.4mm, 1.5~2.4mm, 2.5mm 이상(以上)의 3종(種)으로 분류(分類)한 후(後) 경시적(經時的) 관찰(觀察)에 의(依)한 발육정도(發育程度)를 비교(比較)한 결과(結果) 3종(種)에 대(對)한 배란수(排卵數)의 추이(推移)는 양구(兩區)가 서로 틀려서 총배란수면(總排卵數面)은 Estrogen 병용구(倂用區)가 우수(優秀)하였다 3. 이런 결과(結果)로 미루어 볼때 P.M.S. 주사(注射)에 대(對)한 Estrogen의 병용처리(倂用處理)는 외면적(外面的)으로는 난포발육(卵胞發育)에 대(對)하여 직접(直接) 영향(影響)을 주지 않으나 미피열난포(未破裂卵胞)를 줄여 배란수(排卵數)를 증가(增加)시키는 경향(傾向)을 나타냈다. This study was conducted to induce superovulation by P.M.S. injection and P.M.S. associate with Estrogen comparatively in the rabbit. The results obtained in this study are as follows. At 23-48 hours following mating, there were 21.3-24.1 ova (Ovulation rate was increased 50.5-63.6%) in average in the group of 40 I.U P.M.S. injected per day per herd for 5 days (total 200 I.U. of P.M.S.) and 32.5-37.8 ova (Ovulation rate was increased 87.5-100%) in the group of P.M.S. associats with 0.1mg at 5th day. She number of unovulated-follicle were fewer in P.M.S.-Estrogen group than PMS group. As the result that dia meter of ova were classified in 3 group as 1-1. 4mm, 1.5-2.4mm and 2.5mm and observed, the ova in P.M.S. Estrogen group were slightly larger in size than P.M.S. group. It was conclued that P.M.S. associate with Estrogen injection was not so much effect on growth of ova but effect on ovulation of ova. so the number of ovulated ova were increased than P.M.S. group.
