| Abstract | The aim of this paper was to establish the way parity had an influence on the milk production and lactation length in Romanian Black and White cows from the Didactical Farm Timi s oara. The influence of the parity on the milk production and lactation length was studied on 125 lactations (37 first lactations, 23 second lactations, 29 third lactations, 14 fourth lactations, and 22 fifth and over lactations). The longest lactation was found in the second parity (397.9 days) and the shortest in the 5+ parity (353.3 days). The maximum milk yield per total lactation was attained in the third lactation (5705.4 kg) and the minimum milk yield in the first lactation (4652.6 kg). Variability for this trait was higher in second lactation (20.74%). The lowest variability coefficient was found in the third lactation (v%=15.36%). |
