Genetic health in Czech cattle population

The paper sums up the studies done in the cattle population in the Czech Republic, concerning the genetic health. As for the congenital defects, umbilical hernia was the most frequently noted disorder. In the 90´s, BLAD became a serious problem in the Czech cattle population. However, strict measures have been efficient, and the frequency of heterozygous sires decreased rapidly. The approach to CVM was not consistent enough, and therefore the decrease was somewhat slow. The recessive alleles of bovine citrullinaemia, DUMPS, glycogen storage disease V and II, and factor XI deficiency were not found. Further, the cytogenetic analysis was done. Robertsonian tranclocation affected 0.50% of Czech Simmentals, and 3.57% of beef sires, the Holsteins were not affected. Autosomal aneuploidies were not found, and 2.3% beef animals carried gonosomal triploidy.

Key words: congenital, CVM, BLAD, chromosomal abnormalities, translocation
