The seasonal availability and abundance of the free-living stages of sheep nematodes is a key factor in the occurrence and severity of parasitic infection, and studies of larvae ecology could result in more rational control measures. In the present study seasonal pasture contamination and availability of nematodes for grazing sheep was examined as a baseline work for nematode control program at Namwon Branch, National Animal Breeding Institute during the period April 1988 through March 1989. Standard meteorological measurements were available from Unbong Sub-station, Honam Crops Experiment Station located about 200m from the experimental site. A total of 5 kinds of nematode larvae was detected: Haemonchus contortus was most prevalent (38.0%) with a decreasing order of Ostertagia spp (35.1%), Trichostrongylus spp (19.8%), nematodirus spp (6.6%), and Oesophagostomum spp (0.5%). A succession of species was recorded, in particular Ostertagia spp in May; Haemonchus contortus in June and July; Trichostrongylus spp in July and August; Nematodirus spp in August and September. These results can be incorporated into the nematode control program. To make a more rational control program, however, repeated herbage larval counts should be undertaken soil larval counts and fecal larval counts in the future.

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.

The anthelmintic efficacy of Albendazo1e and Ivermectin against gastrointestinal nematodes, trematodes and cestode was tested in naturally infected Korean native goats. Albendazole was medicated at a dose rate of 10mg/kg of body weight orally and Ivermectin was injected at a dose rate of 0.2mg/kg of body weight subcutaneously. The efficacy was measured by faecal examinations on the day 7th and the day 14th :after treatment. The results obtained were summarized as follows : 1. The efficacy of Albendazole against trematodes and cestode was shown 91.7% in Fasciola hepatica, 68.8% in Paramphislomum spp., 66.7% in Eurytrema pancreaticum and 100% in Moniezia expansa(cestode). 2. The efficacy of Ivermectin against trematodes and cestode was shown 38.8% in Fasciola hepalica, 26.1% in Paramphistomum spp., 22,2% in Eurytrema pancreaticum and 100% in Moniezia expansa(cestode). 3. The anthelmintic efficacy of Albendazole against gastrointestinal nematodes was shown 97.7% in Haemonchus contorus and 100% in Oesophagostomum spp., Ostertagia spp., Bunostomum trigonocephalum, Trichostrongylus spp., Strongyloides papillosus and Cooperia spp. 4. The efficacy of Ivermectin against gastrointestinal nematodes was shown 96.6% in Haemonchus contortus, 94.1% in Trichostrongylus spp. and 100% in Oesophagostomum spp., Ostertagia spp., Bunostomum trigonocephalum, Strongyloides papillosus and Cooperia spp.

It's a case of the goat farm reared about 60 heads in Imsil county was outbreak Moniezia expensa infection. And 18 heads of less than 6 month olds goat were died. During the 2005 summer, morbidity and accumulative mortality were more than 60% and 30%, respectively less than 6 month young goat. Most young goat were suffer from diarrhea, severe weight losses, emaciations, and died. In necropsy, there were about 0.7-2.5m of 2-8 adult M expensa in the small intestinal lumen, swollen mesenteric lymph nodes. Slight hemorrhages were seen in lung and moderate hemorrhages were seen in mucous membrane of small intestine. Also various species (Trichostrongylus spp, Haemonchus spp, Eimeria spp) of parasite eggs were seen in fecal test. Pasteurella hemolytica was identified in lung by the API kit (Biomerieux Co. Ltd) for biochemical test. The minimal inhibitory concentration (MIC) results, trimethoprim/sulfamethoxazole, erythromycin, tyrosine, gentamycin, enrofloxacin, and norflocxacin were selected sensitive antibiotics.

In order to monitor the parasites, 303 fecal samples were taken from Korean native goats (n=279) and sheep(n=24) in Chonbuk area.

The obtained results were summarized as follows ; 1. The detection rate of the parasites from Korean native goats and sheep was 98.2% and 83.3%, respectively. 2. In Korean native goat, mixed infection rate was single 7.5%(21 heads), double 47.3%(132 heads), triple 40.8%(114 heads), quadraple 5.0%(14 heads) and quintuple 2.5%(7 heads). 3. In sheep, mixed infection rate was single 12.5%(3 heads), double 45.8%(13 heads) and triple 16.6%(4 heads). 4.

Research results on actual management situation of 16 goat farms and internal parasite infection of 155 goats from January to November in 1997 in southern Kyoungnam area were as follows ; 1. An average number of goats was 93. Among them, 81% were farming the goat as avocation with the income rate less then 50%, Eight-four percent of farms terminated the parasites more than twice a year, and the survey showed the black goats had a high digestive and respiratory disease infection rate. 2. The internal parasite infection rate of the black goat was 96.8% , the goats were infected with 13 types of parasites. Of them, Emeria sp was 87.1%, Ostertagia sp 55.5%, Paraphistanum sp 45.8%, and Moniezia expansa 20%, respectively. 3. On the survey of multiple infection rate, both double and triple infection were 19.4%, more than septuple-infection 15,5%, single infection 13.4%, quintuple infection 12.3 n, sextuple infection 9.0% and quadruple infection 7.7%, respectively. 4. Look over on seasonal infection rate, higher in fall and lower in winter. Especially, Paramishitom sp was higher in summer and winter, both Moniezia expansan and Bonaostom sp were higher in summer. 5. Research on the infection rate of parasites termination period revealed less-than-1-month period had 10-30 infection rate, the infection rate has increased sharply since 3 months passed after the goats were treated with parasite-cid.

This survey was conducted to investigate the prevalence of the internal parasites of Holstein cattle rearing in western Gyeongnam including Chinyang, Sachun, Namhae, Hadong, Sanchung, Hamyang, Geochang and Hapchun Area(Gun). A total of eight hundred and twenty five heads of Holstein cattle was randomly selected for the faecal examinations and the internal parasitisms were examined by floatation method using saturated salt solution and sedimentation method using 0.5% trio-soap solution. The relults obtained are summarized as follows: 1. The overall rate of internal parasite infections was 67.2% with infection of 554 cases and the non-infected rate was 32.8% with 271 cases from the total number of 825 samples. 2. A total fourteen species of parasites was identified from 825 faecal samples of Holstein cattle and the infection rate of each species of parasites was 3.0% in Haemonchus contortus, 2.7% in Cooperia spp., 1.8% in Bunostomum phlebotomum, 1.6% in Oesophagostomum radiatum, 1.2% in Ostertagia ostertagi, 1.0% in Trichuris bovis, 0.8% in Strongyloides papillsus, 0.4% in Nematodirus spp., 0.1% in Trichostrongylus spp., 57.3% in Paramohistomum spp., 31.2% in Fasciola hepatica, 0.6% in Eurytrema pancreaticum, 0.7% in Moniezia expansa and 5.1% in Eimeria spp. 3. The combined infection of internal parasites was 38.1% in single species, 27.0% in double and 2.1% in triple infections. 4. The EPG levels of each species of parasites were very low in all infected cases except trematodes showing no clinical symptoms.
