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.

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 identification of the parasites were determimed by the fecal examination using the floatation or sedimentation methods and microscopical examination, respectively. 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. The parasites isolated were identified as Eimeria spp. from 283 heads, Oesophagostomum spp. from 96 heads, Ostertagia spp. from 97 heads, Strongylodes papillus from 97 heads, Heamonchs spp. from 73 heads, Trichostrongylus spp. from 42 heads, Moniezia expenza from 26 heads, Cooperia spp. from 16 heads, Nematodirus spp. from 9 heads, Bonostomum spp. from 9 heads, Paraphistomum spp. from 7 heads, and Fasciola hepatica and Capillaria spp. In 2 heads, in order.

Wildlife has been recognized that has important role as reservoir hosts of disease affecting both people and livestocks. However, information intestinal helminths of Korean water deer were limited. We obtained 20 feces from Korean water deers that were transferred to veterinary hospital in Chungbuk National University from May 2010 to June 2011. Parasite ova were collected using saturated zinc sulfate floatation method. Parasite eggs were examined and measured using light microscope. The identification of parasitic eggs was done by morphological characters. The overall infection rate of parasite was 85% (n=17). The eggs were observed as being Nematodirus spp. (n=14), strongyles egg (n=11), Capillaria spp. (n=9), Trichuris spp. (n=7), Eimeria spp. (n=4), Ogmocotyle spp. (n=3), and Strongyloides (n=1). Mixed infection rate was observed as being single 15% (n=3), double 20% (n=3), triple 15% (n=3), quadruple 30% (n=6), and quintuple 5% (n=1). The Ogmocotyle spp. was first reported in Korea.

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.

A 3 yr experiment was conducted to evaluate the influence of diet and feeding location on animal performance, carcass characteristics, whole blood counts, and internal parasite burden of lambs assigned to 1 of 4 treatments: 1) confinement fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (CALF), 2) confinement fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (CBAR), 3) field fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (FALF), and 4) field fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (FBAR). A year × location interaction was detected for ending body weight (BW), average daily gain (ADG), and dry matter intake (DMI); therefore results are presented by year. In all years, cost of gain and DMI were greater for CALF and FALF than for CBAR and FBAR feed treatments (p ≤ 0.03). In yr 2 and 3 field treatments had greater ending BW and ADG than confinement treatments. For all years, diet did not affect ending BW or ADG. In yr 1 dressing percent and rib eye area were greater for field finished lambs than confinement finished (p ≤ 0.02) and Warner-Bratzler shear force was greater for CALF and FALF (p = 0.03). In yr 2 lambs in FALF and FBAR treatments had greater leg scores and conformation than CALF and CBAR (p = 0.09). In yr 1, FALF had a greater small intestine total worm count than all other treatments. In yr 1, ending Trichostrongyle type egg counts were greater for FALF (p = 0.05). In yr 2, ending Nematodirus spp. egg counts were greater for FALF and lowest for CBAR (p < 0.01). Abomasum Teladorsagia circumcinta worm burden was greater in CALF than all other treatments (p = 0.07) in yr 2. While field finishing lambs with a grain- or forage-based diet we conclude that it is possible to produce a quality lamb product without adverse effects to animal performance, carcass quality or increasing parasite burdens.
