The aim of the paper was to study the length of days open in Romanian Black and White cows according to county and parity. Researches were carried out on 3167 lactations obtained from 1200 cows reared in Timiş and Caraş-Severin counties. Average days open was 163.5 days (5 months and 11 days) for cows in Timiş County and 122.7 days (4 months and one day) for cows in Caraş-Severin County. The difference of 40.8 days in the favor of cows from Timiş County was significant (p0.05) for days open between parities for cows in Caraş-Severin County.
