Abstract
    In this paper we present the research results on a herd of 145 Fleckvieh cows with the aim of production and reproduction capacity. The objectives of the research were: duration of total and normal lactation, milk quantity, fat percent and quantity, protein percent and quantity, age of first calving (days), breast rest (days), calving-interval (days), service-period (days), duration of gestation (days) etc. The population had 5628.01 kg of milk per total lactation (in the second lactation), and the quality of milk had over 4% fat and over 3.4% protein. Following the evolution of milk production on successive lactations indicated 91.81% of normal lactation. For the studied herd, the age at first calving was 835.49 days (27 months and 25 days); the calving-interval (CI) on successive lactations ranged between 469.45 days (lactation II-III) and 397.17 days (lactation VII-VIII); breast rest (MRI) on successive lactations, ranged between 76.58 days (lactation II) and 64.67 days (lactation VIII), recording optimal values for all lactations; the service-period (SP) showed average values that far exceed the average values in a normal holding. Depending on lactation, they ranged from 186.45 days (lactation III) to 110.17 days (lactation VIII)
