Studies on the diagnosis of subclinical mastitis in cows by the measurement of the electrical conductivity, 1; comparison of various methods of handling conductivity data with the use of California mastitis test and direct somatic cell count
1984
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

1984
Lim, Y.J. (Yongin Farm Land Animal and Hospital, Yongin (Korea R.)) | Shozo, S. (Tokyo Univ. of Agriculture Tokyo (Japan))
The hemoglobin phenotype and the gene frequencies of 44 Formosan deer (Cervus nippon) in Kyunggido Korea [R.] area were examined by using cellulose acetate and starch gel electrophoresis. The method of cellulose acetate electrophoresis was simpler, more clear and preserative than starch gel electrophoresis. The hemoglobin phenotype had 3 types as (HbF) (HbFS and HbS). The frequencies of appearence were HbF 47.7% HbFS 47.7% and HbS 4.5%, respectively. The genetic factors of hemoglobin were observed as HbF and HbS and the rates of gene frequencies were 71.6% and 28.4% respectively
