Abstract

The aim of the current research was to determine the influence of calving year and season on calving interval (CI) in
Romanian Brown breed. A total of 250 data recorded from 150 lactations of 50 Romanian Brown cows raised between
2018 and 2020 were included in the current study. The year proved to exert a significant effect (p≤0.01) on calving
interval, this parameter recording an increased tendency. Comparable values were recorded according to season of
calving (p>0.05). Concluding, year of calving was the main influential factors for this particularly reproductive trait.
In this respect, additional studies should be performed in order to include other factors, validate their influence and
properly manage of its.
