Although Fleckvieh are male and large-sized, they have a good temperament and are easy to handle. One of the most important characteristics of the Fleckvieh breed is their excellent maternal instinct. A cow can become pregnant as early as 15 months and has a healthy calf. She can become pregnant again while nursing her calf. This is a beneficial trait, as Fleckvieh can maintain a 365-day calving interval. A good breeding Simmental cow can produce an average of 7.3 to 10.9 kg of milk per day.
