The analysis was performed into a farm at the first and second lactations. The imported dairy cattle (Schwyz breed) were compared with contemporaries indigenous breed (Bruna of Maramures) calved in the same period. Both breeds were kept in the same conditions and with the same feeding. The first lactation records were analyzed according to the following linear model: Yij =μ + Hi + Cj + eij. The second lactation records were analyzed according to the following linear model: Yijk =μ + Hi + Cj + Jk + eijk. The difference in milk production between Schwyz and Bruna of Maramures breeds, at first and second lactations, were not statistically significant. The Schwyz breed cattle achieved higher fat, protein and lactose percentage at the first lactation (4.25% and 3.94%, 3.42% and 3.20%, respectively 4.67% and 4.49%) and at the second lactation (4.29% and 4.02%, 3.42% and 3.21%, respectively 4.59% and 4.43%). These differences were statistically highly significant (P<0.01).Read More
