The objective of this study was to analyze the relationships among cows BCS before calving, subsequent BCS changes, milk yield, lactation characteristics and their sires relative breeding value for net daily gain. Regarding the results, it may be statedthat BCS measurement can be an effective tool for general management improvement also in dual-purpose herds. The genetic merit of cows sires for beef production efficiency did not have a statistically significant effect either on BCS development in the particular lactation periods or on the milk yield of their daughters. It can be recommended to include BCS evaluation in the exterior classification in Czech Fleckvieh cows similarly like it is used in other countries with the advanced breeding of Holstein cattle. These results show that it is also possible to select the Czech Fleckvieh population for good BCS and optimal milk yield.
