| Summary: | Use of quality sires in the artificial insemination of cattle leads to the
increased production in cattle breeding. In EU countries and the countries
which cooperate in semen trade with EU countries bulls’ health status and
minimal criteria for semen quality are regulated by law. Bull semen quality
is influenced by several exogenous factors. Semen quality parameters are
influenced by season. The highest values of ejaculate volume and total sperm
output were found during the summer, while the lowest values were found in
winter period. Some xenobiotics can also affect semen parameters. Correlation
between semen quality and pesticide use in limited geographic area was found,
namely bull semen quality decreased in the period when pesticide use
increased. |
