Molecular-genetic approaches in poultry breeding

Poultry farming is an animal breeding industry addressing the need for eggs and meat with prominent delicacy qualities. Modern, highly productive breeds need to be created and maintained in order to let this industry meet the consumers’ demands. With the following literature overview we aimed to examine the studies evaluating the candidate genes that are related to birds’ productivity. Molecular-genetic approaches such as sequencing, Genome Wide Association Studies, Microsatellite markers, Real time PCR, PCR-RFLP enable the discovery of the genetic mechanisms that regulate the processes in organisms, thus affecting the desired productive qualities of farm animals. Meat and egg productivity directly depend on a number of genetic and non-genetic factors. The genetic factors include a wide variety of genes that control the expression of proteins involved in various biochemical processes
