摘要

The analysis concerned the longevity and production period of beef cattle of seven breeds born in 1990-2011, as well as the reasons for culling the animals. We observed a distinct tendency for a decrease in the average production period in beef cattle herds. It has been estimated that the longevity of beef cattle is influenced highly significantly by the sex, breed, birth year, and birth season. Most animals were culled between the 6th and 12th month of age.
