A comparison of lactation physiology effects at high and lower yield on components, properties and health state indicators of milk in Czech Fleckvieh

Popis výsledku v původním jazyce

The milk yield (MY) is one of the main efficiencies of Czech Fleckvieh (CF) cattle. MY is a significant economic and health factor. Differences within milk indicators (MIs) between two CF dairy cow groups with high (CF1; n = 213 individual milk samples (animals)) and lower (CF2; n = 265) MY were tested. The files were balanced in factors of lactation. Group 1 had higher genetical value and had even better nutrition according to the MY. Average daily milk yield of CF1 was higher by 56 % as compared to CF2 (P < 0.001). Significant differences (P < 0.001) were determined for: fat (FAT); lactose (LAC); solids non fat (SNF); log somatic cell count (log SCC); crude protein (CP); casein (CAS); true protein (TP); fat/crude protein ratio (F/CP). FAT, LAC and SNF differed markedly (P < 0,001) in this way the CF1 cows had lower milk FAT, LAC and SNF as compared to CF2 (3.71 - 4.33 %, 5.00 - 4.92 % and 8.83 - 8.97 %). The log SCC was significantly lower in CF1 dairy cows (xg 50 - 74 103.ml-1).
