Abstract


The aim of this study was to compare the milk production of the Romanian Black and White cows raised in two counties (Timiş and Caraş-Severin) from the western Romania. Researches were carried out on 3,579 lactations (3,110 from Timiş and 469 from Caraş-Severin) finished in year 2008. Results showed that cows in Caraş- Severin produced significantly more milk per lactation compared to cows from Timiş (p<0.05), except for the butterfat percentage (p>0.05). On average, cows from Caraş-Severin produced 4710.9 kg milk with 3.939% butterfat, 186.13 kg butterfat, 3.337% protein and 156.92 kg protein per normal lactation, while cows from Timiş produced 4216.5 kg milk with 3.948% butterfat, 166.22 kg butterfat, 3.130% protein, and 131.22 kg protein. Differences for milk production per total lactation were lower, but still significantly different (p<0.05). Cows in Timiş had longer days in milk than cows in Caraş-Severin (363.7 vs. 341.2 days, p<0.001).
