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.

This experiment was carried out to investigate the hematological and blood chemical values in dairy cattle during the dry and lactating period. Blood was collected from six healthy dairy cattle in Gyeongnam province. Leucocytes count, hemoglobin concentrations and the percentage of packed cell volume were lowest at the early lactation period. Leucocytes count was not affected during dry the to lactating period. The differential count of eosinophilic leucocytes was low at the late lactation period, while the basophilic leucocytes was high at the dry period. Inorganic phosphorus value was below under normal level. Creatinine value was from 1 to 2mg/100ml of serum. Positive reaction to CRP was shown in normal dairy cattle. The values of AST and ALT were higher during the dry than lactating period. r-GTP and total cholesterol tend to be decreased during the lactating period. CPK value was not affected for dry and lactating period.

This survey was carried out to investigate the incidence of subclinical mastitis in dairy cows of Gyeongnam area from March 1987 to February 1988. Also performed were the isolation of microorganisms from RBV positive milk samples and drug susceptibility testing of the isolates. Two hundred and thirty-eight cows(43.2%) of 655 cows were found to be infected with subclinical mastitis and infection rate in quarters was 19.9% of 2,595 quarters. The incidence of subclinical mastitis was significantly increased with advancing parity. In the incidence of subclinical mastitis by hygiene control of lactating cows, disinfectant udder wash, teat dipping and post hand-milking treatments were highly effective for diminishing of the incidence of subclinical mastitis, but drying cow therapy was little effect. The causative organisms isolated in order of prevalence were Staphylococcus aureus(40.0%), Staphylococcus epidermidis(18.5%), Micrococcus spp.(15.0%), Bacillus spp.(9.1%). Streptococcus dysgalactiae(7.2%), Escherichia coli(4.3%), Streptococcus uderis(3.1%), Streptococcus agalactiae(1.4%) and Corynebacterium spp.(1.3%). The 404 isolates of Staphylococcus spp., 65 Streptococcus spp. and 50 Bacillus spp. were highly sensitive to cephalothin and chloramphenicol, while all of them were highly resistant to streptomycin and colistin. Twenty-four strains of Escherichia coli were resistant to penicillin, streptomycin and kanamycin. but were mostly sensitive to chloramphenicol.
