| description | The aim of this study was to analyse the effect of the temperament of cows on
their lifetime production efficiency. Data on milk performance, longevity
and culling reasons of 11 629 Polish Holstein-Friesian cows were extracted
from the SYMLEK database. Using the methodology of the Polish Federation of
Cattle Breeders and Dairy Farmers, cow temperament was assessed as follows: 1 –
calm; 2 – normal; and 3 – excitable or aggressive. Most cows showed a normal
temperament (89.52 %). Over successive years of the evaluation, there
were increases in the proportion of cows with a calm (from 2.98 to 6.85 %)
and excitable temperament (from 7.50 to 8.27 %). Temperament
was found to have a highly significant effect on first lactation milk yield,
first lactation daily milk yield, milk yield per day of age, and milk yield
per day of productive life. In cows with a calm temperament, first lactation
milk yield was 621 kg higher than in cows with a normal temperament and 329 kg
higher compared to excitable (aggressive) cows. |
