Kang, B.K. (Chonnam National Univ., Kwangju (Korea R.). Coll. of Agriculture. Dept. of Veterinary Medicine)
A total of 466 foremilk from dairy farms in Chonnam Korea [R.] district was examined for the subclinical mastitis over a period of 1 year, using a method of the electrical conductivities (EC); absolute conductivity (AC) and differential conductivity (DC) and quarter difference value (QD), in relation to the California mastitis test (CMT) and the direst somatic cell count (DSCC). The compatibility and efficiency rating between the EC values and the other screening tests was conducted

In the evaluation of anthelmintic efficacy by fecal egg counts for cattle naturally infected with helminths, the reasonable technique of fecal egg counts and the reliable guidelines were determined. Modified technique of Harashigeru and Kim's sedimental tube was the most reasonable in fluke egg counts. Universal egg counting technique was preciser than McMaster egg counting technique and was lower in coefficient variation. Fecal egg counts of pretreatment should be carried out twice and mean of the egg should be calculated
