This study was performed to survey on the prevalence of swine internal parasites at 12 piggeries being operated by the sawdust fermentative pigsty in Kyongnam central area. To investigate the effects of viability of eggs, larva and cysts, temperatures at the underlayer of the sawdust floor and rooms of pens were taken four times each season for one year. In a pig farms which have been operated by the sawdust fermentative pigsty, eggs of Ascar is suum(8.8%), Trichr is suis(18.3%), Oesophagostomum sp(9.4%), Strongyloides ransomi(1.3%), Hyostrongylus sp(3.8%) and Metastronylus apri(2.3%) were detected from 480 heads of Pigs. Cysts and oocysts of Coccidia(12.7%), Balantidium coli(5.4%) were also detected form 480 heads of pigs. The change of the temperature in the pig room was variable between $13^{\circ}C\; to\; 27^{\circ}C$ accord-ing to outside condition, whereas that in underfloor was consistently stable between $28^{\circ}C \;to\; 31^{\circ}C$ which was strictly suitable for the development of eggs, larva and cysts.

In order to monitor the parasites, fecal samples were taken from turkey (n=157), helmeted guineafowl(n=149), pheasant(n=190) and duck(n=190) in Chonbuk province. The identification of the parasites were determined by the fecal examination using the fluatation method and microscopical examination. The results were obtained as follows；1. The detection rate oi the parasites from 4 species of poutry was 47.2%(n=324 heads) out of 686 heads. 2. The identification rate was 85.9% in helmeted guineafowl, 63.2% in pheasant, 44.6% in turkey and 3.2% in duck, in order. 3. The mixed infection rate such as single, double, triple and quadrupl was 25.4%(174 heads), 14.1%(97 heads), 7.3%(50 heads) and 0.4%(3 heads), respectively. 4. The parasites isolated were identified as Capillaria spp. in 225 heads, Eimeria spp in 169 heads, Heterakis gallinarum in 116 heads, Ascaridia galli in 16 heads, Hymenolepis spp. in 3 heads and Strongyloides avium in 1 head, in order.

From September 1997 to August 1998, Korean indigeous goats infected with internal parasites were examined for efficacy of anthelminthics by fecal egg counts. Efficacy of anthelmintic drugs against gastointestinal Haemonchus contortus in goats were effective with Ivermectin(94.9%), Piperazine(92.8%), Levamisole(88.3%), Albendazole(68.2%), respectively. Albendazole was effective against goats with Haemonchus contortus in 3 herds, but not effective in 1 herds. Efficacy of anthelmintic drugs against gastointestinal Paramphistomim sp in goats were effective with Ivermectin(95.3%), Piperazine(93.3%), Albendazole(92.9%), Levamisole(91.1%), respectively. Efficacy of anthelmintic drugs against Eimeria sp in goats were effective with Toltrazuril(92.6%), Diclazuril(90.4% ), Nicarbazin (87.5%), Amprolium(70.0%), respectively. Amprolium was effective against goats with Eimeria sp in 3 herds, but not effective in 1 herds.

Observations were made on the infection rate of common internal parasites in dogs in Kwangju area from January to March, 1982. Dog's stools were collected from veterinary hospitals, houses, intensive dog-rearing places and sidewalks. On the basis of egg counting, the following results were obtained; 1. Of 464 fecal samples, 73.5% were appeared as positive. 2. Dogs from veterinary hospitals and intensive dog-rearing places have higher infection rates than others. 3. Of the parasites detected, Toxocara canis was the most commonly encountered (23.7%). 4. Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas bookworms were detected less often in young dogs than in older ones. 5. There were significant (p<0.01) differences among age categories for all parasites except tapeworms.

From December 1995 to July 1997, a total of 546 Korean indigenous goats were examined for the presence of internal parasites by parenchymal organs and fecal examinations. Four hundreds seventy eight(87.5%) of the goats were infected with 4 classes and 12 parasitic species. The nematodes were Haemonchus contortus(57.5%), Oesophagostomun venulosum (52.6%), Strongyloides papillosus(48.4%), Ostertagia sp(28.4%), Trichostrongylus colubriformis(17.0%), and Trichuris ovis(13.2%). The trematodes were Paramphistomum sp(17.6%), Fasciola hepatica(15.4%), and Eurytrema Pancreaticum (8.8%). The cestode was Moniezia expansa(16.7%), and the protozoa were Eimeria sp(74.9%) and Toxoplasma gondii(8.6%). The incidence of single or mixed infections among 12 parasitic species were one species infection (6.2%), 2 species(11.5%), 3 species(19.6%), 4 species(24.9%), 5 species(17.8%), 6 species(5.9 %), and 7 species(1.6), respectively. The level of infection according to the age was considerably higher under one year(97.2%) than between one and two years(89.7%), and over two years(69.3%) Among 12 parasites, seasonal pattern was remarkably observed. Most paracites were detected at the highest level in the Winter, whereas Strongyloides papillosus and Paramphistomum sp were in the Spring, and Ostertagia sp and Fasciola hepatica were in the Autumn. Infection rates of Anaplasma sp were 8.6% of 210 goats by blood smear method, and 51.0% by complement fixation test.

Preliminary survey on the prevalence of swine internal parasites was carried out at 91 pens of 4 piggeries being operated by the sawdust fermentation floor system in Kyunggi province. To investigate the effects of viability of eggs., larva and cysts, temperatures at the underlayer of the sawdust floor and rooms of pens were taken three times a day for 8 days. In a pig farm which has been operated by the sawdust fermentation floor system for G years, eggs and larva of Ascaris suum, Trichuris suis, Oesophagostomum sp., Hyostrongylus sp. and Strongyloides ransomi were detected from 42(70.0%) among 60 pens. Cysts and oocysts of coccidia, Balantidium coli, Entamoeba sp. were also detected from 50(83.3%) among 60 pens. In three pig farms which have been operated by the sawdust fermentation floor system for one year, eggs and larva of nematoda were not detected at all, and the contamination rates of protozoan cysts and oocysts was relatively low situation. The change of the temperature in the pig room was variable according to outside condition, whereas that in underfloor was consistently stable between $28^{\circ}C$ to $30^{\circ}C$ which was strictly suitable for the development of eggs, larva and cysts.

Parasites cause great economic loss in livestock in Korea, and can be categorized as either or indirect losses. In order to monitor the parasites from October 2005 to January 2006, 401 samples were randomly collected from cattle farms and examined the prevalence of gastro-intestinal (GI) parasites by using the sucrose flotation method and formalin-ether centrifugation method. The overall infection rate of GI parasites was about 43.4%. Of these parasites, nematodes were identified as Capillaria bovis (5.5%), Strongyloides papillosus (2.5%), Trichuris discolor (1.2%). Cestoda was observed only one species, Moniezia benedeni (2.2%). The rate of Eimeria spp was 39.2%. A total of five species of Eimeria was identified; among the species identified as above E bovis and E zuernii appeared with relatively higher infection rates. The combined infection of parasites was 35.2% in single species, 29.0% in double and 2.0% in triple infections. No cases of clinical symptoms were observed in this survey. The EPG levels of each species of parasites were very low in all infected cases.
