The present study was carried out to investigate effects of various factors such as sire, bovine leukemia virus(BLV) carrier/non-carrier, parity, calving month and lactation periods on somatic cell count(SCC) and milk components in dairy cows. The animals calved from January 2001 to March 2004. Milk samples were collected every 30±5 days in milk(DIM), and somatic cell count and milk components were analysed by Somascope MK2/Lactoscope FTIR. Bovine Leukemia Virus(BLV) was detected by ELISA method.
