Abstract

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.

Key Words: dry and lactating periods, hematological and blood chemical findings, dairy cattle
