Swine proliferative enteritis(SPE) caused by inかsoma intracellularis is a common enteric disaese of grower and finisher pig. Swine affected with SPE show variable clinical signs including diarrhea, weight loss, aberrant growth and death. The characteristic lesion of ileitis at necropsy is marked thickening of the last section of the small intestine. The inner lining of the thickened intestine proliferates almost like a cancer and curved rod bacteria(L intracellularis) are always seen inside the intestinal wall. Infected swine shed the organism in the feces. Isolation and growth of pure L intracellularis in vitro requires a suitable cell culture. This procedure is difficult and not a practical means of diagnosis, thus the polymerase chain reaction(PCR) test of feces can be used to determine whether a pig is shedding the infective organism. A sensitive assay based on amplification of a 319bp DffA fragment of the L intracellularis of Swine proliferative enteritis was attempted for the detection of the organism in the 62 feces of swine. L intracellularis was identified on three herds and detected in 6 fecal samples, representing a infection rate of 9.7%. The PCR was very sensitive and specific on the individual level. The PCR technique could be very useful for the diagnosis of this disease.

Current treatments for canine Giardia infections include albendazole, fenbendazole and metronidazole in the most cases. To compare efficacy of these antimicrobial drugs for treating naturally infected giardiasis in dogs, we used the zinc sulfate concentration technique(ZSCT) to figure out naturally infected with Giardia. In this study, feces were collected from 150 asymptomatic dogs at a kennel, 28 asymptomatic Giardia infected dogs were used by the allocated four group to receive albendazole(group A, 25 mg/kg, PO, bid, 7 days), fenbendazole(group F, 50 mg/kg, PO, sid, 7 days), metronidazole (group M, 50 mg/kg, PO, sid, 7 days), nontreated control(group NC) respectively. Fecal samples from each dog were examined for Giardia cysts within 3 days of the last treatment. Giardia cysts were not detected in the feces of any dog in group F. Cysts were detected in the feces 1 of 7 dogs in group A or in the feces 2 of 7 dogs in group M. In the group NC, cysts were detected in the feces of 7 of 7 dogs. Finally, there was significant difference for efficacy between antimicrobial drugs against Giardia in dogs. Fenbendazo1e is the most efficacy to have giardiacidal activity.

This study was conducted to examine the enteropathogens and clinical aspects of diarrhea of the 211 Korean native calves during the suckling period. The experimental results were summerized as follows: 1. The 206 Korean native calves (97.6%) were affected with diarrhea during the suckling period. 2. Of 156 diarrheal feces tested, Rotavirus were detected from 108(69.2%) feces of $K^+99$ E coli were detected from 23(14.7%) feces and Eimeria spp were detected from 33(21.2%) feces. But Salmonella spp and Cryptosporidium spp were not detected. 3. Rotavirus were detected from 2 to 84 days of life, $K^+99$ E coli were detected from 5 to 54 days and Eimeria spp were detected from 33 to 84 days of life. 4. Physical appearances of the diarrheal feces were not affected specifically according to the enteropathogens, but were affected by the severity of diarrhea and the diets.

초지 또는 농경지에 살포되는 퇴비와 액비에 의해 발생될 수 있는 악취민원에 대처하기 위하여, 돼지의 분과 뇨에 존재하는 악취물질 농도를 비교 분석하였다. 1. 비육돈의 분과 뇨에 함유된 휘발성유기물의 농도 비교 페놀, p-크레졸 및 페놀류 농도는 분 보다 뇨에서 높았으며 (p<0.05), 분 보다 뇨에 축적된 비율이 페놀은 138배, p-크레졸은 545배 높았다. 인돌 농도는 분 보다 뇨에서 높았으며, 스카톨은 뇨 보다 분에서 높았다 (p<0.05). 휘발성유기물은 대부분 뇨로 배설되었으며, 이 중 농도 및 악취강도가 가장 높은 물질인 p-크레졸이 뇨에 많이 함유되어 있다. 돼지 분뇨를 고액분리 하였을 때 퇴비로 이용되는 고체보다 액비로 이용되는 액상물질에서 악취가 훨씬 강할 것으로 예측된다. 2. 비육돈의 분과 뇨에 함유된 휘발성지방산의 농도 비교 아세트산과 단쇄지방산 농도는 분 보다 뇨에서 높았으며 (p<0.05), 부티르산과 프로피온산은 차이가 없었다 (p>0.05). 이성체지방산 중 I-부티르산의 농도는 뇨 보다 분에서 높았지만 (p<0.05), I-발레르산과 이성체지방산은 차이가 없었다 (p>0.05). 휘발성지방산 중에서 아세트산과 프로피온산은 분에서 각각 65와 20%, 뇨에서는 각각 93과 4%로 휘발성지방산의 대부분을 차지하였지만 아세트산과 프로피온산을 포함하는 단쇄지방산은 악취강도가 낮다. 반면에 악취강도가 상대적으로 높은 이성체지방산은 분과 뇨 간에 차이가 없기 때문에 휘발성지방산이 악취강도에 미치는 영향은 크지 않을 것으로 판단된다. 이상의 연구결과를 종합하면, 돼지 분뇨의 악취물질 중 악취강도가 높은 p-크레졸은 뇨에 많이 함유되어 있기 때문에 퇴비와 액비 생산과정 중 액상처리 시 악취강도가 매우 높을 것으로 추정된다. 다만, 악취강도는 휘발성지방산의 농도 변화에 따라 차이가 있을 것으로 생각된다.

Two 3-month old Wistar Strain male rats (weights was 270g and 340g respectively) were used as samples in order to determine the daily excretion of thiamine contained in urine and feces by the thiochrome reaction. The results were as follows. 1. Daily excretion of urine was 5,2 cc per 100 grams of body weight and that of thiamine was $18.65\;{\gamma}$ per 100 grams of plasma. 2. Daily excretion of feces was 2.4 grams per 100 grams of body weight and that of thiamine was $7.24\;{\gamma}$ per 100 grams of plasma. 3. Daily excretion of thiamine contained in urine is about twice the amount of thiamine excretion contained in feces. Thus, it can be concluded that more of the excretion of thiamine was mainly excreted through urine.

To monitor the reproductive patterns of endangered orangutan, Time-resolved fluorescence immuno assay (TR-FIA) were used to analyze metabolites of sex hormones in feces. Orangutan had long-term interbirth intervals (amenorrhea) during lactation period in which the secretion of sex hormones was repressed. The concentration of progesterone in the serum of pregnant orangutan was 30fold higher than that in non-pregnant orangutan. However, the concentration of hCG during pregnant period was different from the result of other primates. The present study suggested that age is not the important factor in determining the reproduction capability, because it is rather greatly influenced by the combination of various factors. Tracing metabolites of sex hormones in orangutan feces seems to be provide the effective solution for the infertility in orangutan. This study result shows the basic data in operating conservation project for endangered orangutan.

The present study investigated the feces production rate and fecal nitrogen production ratio of abalone, Haliotis discus hannai fed seaweed, Undaria pinnatifida. The abalone, with shell lengths of 3 cm, 5 cm, and 7 cm, were tested at temperatures of $12^{\circ}C$, $16^{\circ}C$, and $20^{\circ}C$ in a semi-recirculating aquaculture system. Under the given experimental conditions, the weight specific feces production rate (FPw) of the abalone increased with the decrease of shell length and the increase of temperature. The relationship of the FPw was. $FPw=-3.092+206.573/T - 1916.8/T^2+0.141L -0.037L^2(r^2=0.9412)$. In addition the abalone produced 17.8-22.5% of fecal material against ingested seaweed, Undaria pinnatifida, and $18.4-22.4\%$ of nitrogen ingested total nitrogen.

Crude protein and digestible energy were 14% and 3,467 kcal in diet, respectively. Average body weight of sow was 237.5kg. Feces with urine was produced 6.98kg per day by lactating sow ranging from 5.72 to 7.93kg. Manure solid was produced 2.75 kg per day ranging from 2.17 to 3.87kg and urine 4.23kg per day ranging from 3.55 to 4.06kg, respectively. Dry matter of feces and urine were 29.91 and 1.54%, respectively. Nitrogen and phosphorus contents in fresh feces were 0.86 and 0.30%, respectively. Nitrogen content in urine was 0.86, and phosphorus in urine was 0.47%. pH in manure was 6.73 and in urine was 8.38 respectively. Biochemical oxygen demand and suspended solid in urine were 5,196 and 308mg/$\ell$, respectively.
