The paper aims to highlight the productive performance of the Pinzgau breed exploited in the Dornelor Basin, Suceava County. In this sense, a herd of 12 head of cattle, belonging to the Pinzgau breed, was studied, both the red variety and the black variety, which were followed by the productive performances at the ascendancy and descent of the nucleus from the farm. Also, the parameters regarding the quality of milk obtained from the studied cattle were analyzed. The ancestry of the studied herd is valuable with productions in the mother (M) of 5496 kg of milk, 4.22% fat and 3.39% protein, in the mother of the father (MT) of 5562 kg of milk, with 4.095% fat and 3.45% protein, and in the mother's mother (MM) of 5613 kg milk with 4.21% fat and 3.49% protein. The milk production in the offspring had an increasing evolution as follows: on total lactation 5922 Kg milk in lactation I and 6474 Kg milk in lactation II, and on normal lactation of 4820 Kg milk in lactation I and 4843 Kg milk in lactation II with average values of 4.26% fat and 3.24% protein in lactation I respectively 3.91% fat and 3.29% protein in lactation II. Regarding the quality of the milk, it had an average value of 86,000 thousand / ml milk in the total number of somatic cells (NCS) which shows us a quality milking, in hygienic conditions, respectively keeping the milk after milking in hygienic conditions, which shows the farmer's care for the cattle on the farm.

In this study, the productive performances of the ascendants and descendants of the cows' herd belonging to the 4 basic breeds were analyzed, as follows: Holstein, Băl?ată cu negru românească (Romanian Black Spotted), Băl?ată românească (Romanian Spotted), and Brună de Maramure? (Maramures Bown), from 7 farms of Neam? county, which were encoded with numbers from 1 to 7. For the analysis of the ascendants' performances - mother (M), paternal grandmother (MT), and maternal grandmother (MM) - and of the offspring' performance, 3 indicators were determined regarding the milk production: the quantity per normal lactation (kg), the percent of fat, and the percent of protein. It was found that the best milk production in normal lactation of offspring was recorded in farm 2 (6161.25 kg), where a mixed herd of Holstein and Băl?ată cu negru românească breeds is raised. If we compare the phenotypic performances of the ascendants (mother of mother - MM), which realized an average milk production of 7205.44 kg, with the father's mother (MT) of 11.931 kg, and the mother's mother (MM) of 7949.83 kg we confirm that the phenotypic performance for the milk production in the offspring does not reach the level of those obtained by ancestry. This fact is due to management deficiency regarding the external factors. [ABSTRACT FROM AUTHOR]
