Vliv růstové intenzity jalovic českého strakatého plemene skotu na jejich mléčnou užitkovost

The aim of this dissertation was to analyze the relation between the growth intensity of Czech Fleckvieh heifers and their milk production. The dissertation can be divided into five parts. In the first part, the age, weight and average daily gain of the heifers was determined. For the whole research period, 8985 individual weighings were performed. In the second part of the dissertation, the condition of 538 heifers together with the measurement of their cross height was evaluated. In the third part of this work, weighing of live weight of heifers was assessed in relation to their subsequent milk production, which was found in 1867 breeding females with 4536 weighings. The fourth part of the thesis evaluated the effect of age at first calving on selected indicators of milk production in individual lactations in 7871 milk cows. In the fifth part, the influence of the daily gain of heifers on selected meat production indicators was analyzed, where the total number of analyzed heifers was 480 pieces. All the evaluated breeding females were recorded in the main section of the Czech Fleckvieh herd book. In cases where the average daily gain of live weight was measured, the weight of the calf at birth of 32 kg was taken as the initial live weight. The statistical evaluation of the results was carried out in the SAS program. Evaluating the growth of heifers, good results of BCS were achieved by heifers with a high intensity of their growth. The heifers, which reached the highest gains, also had the highest cross height values. Furthermore, it can be stated that the average daily gain of 0.801 to 0.999 kg/day is optimal, as for the milk production, for the heifers aged up to 7 months. An optimal daily gain of older heifers was over 1.000 kg/day. In this dissertation, it was confirmed that the ideal age for the first calving is in the range of 23 to 26 months. When analyzing the beef production of heifers, it was proven that the breeding cows with higher daily gains achieve better classification and heavier carcass weights.
