Cytogenetic tests are effective tools for monitoring the health status of livestock and improving their genetic value. Cytogenetic screening allows for the detection of animals carrying chromosomal aberrations and to avoid using them as breeders. Progress in karyotype monitoring, with new molecular probes and automation, has greatly increased the productivity of this procedure. Several genotoxicity tests are available to detect the possible presence and effects of pollutants or drugs. Among these, the micronucleus test and the Comet assay are the most convenient in terms of costs and benefits. Finally, analysis of telomeres, the end of chromosomes and markers of genomic instability, may be developed into a new marker of stress and genetic value.
