Abstract

Cytogenetic studies enable the identification and early elimination from breeding of animals affected by hereditary karyotype defects. These defects cause developmental disorders and a significant decrease of fertility parameters (from a few dozen to 100%) and productivity of breeding herds, and consequently measurable financial losses. Due to the potential possibility of spontaneous occurrence of chromosomal aberrations and rapid spreading of these genetic defects in the population, especially in the conditions of the use of artificial insemination, it is necessary to carry out regular karyotype control of breeding animals. Cytogenetic monitoring of cattle qualified for reproduction guarantees the systematic identification of all karyotype abnormalities carriers, which, causing the decrease of fertility or sterility, determine the low reproductive performance of animals affected by these defects. The cytogenetic control system, implemented by the use of constantly perfected cytomolecular techniques, enables a very precise, reliable evaluation of karyotype and diagnosis of chromosomal abnormalities, as well as formulation of specific recommendations for culling.
