Some aspects of DNA analysis in the selection of small ruminants

Abstract

DNA analysis can have great practical application in the management and successful operation of the farm. The application of DNA technology is becoming a tremendous challenge for farm breeding of domestic animals. In recent years, traditional selection methods have been supplement by the results of molecular analysis of the genome. Determining the genetic distance of sheep and goat breeds had practical and multiple significance. Microsatellites are used widely in the selection, and genomic selection is becoming an increasing challenge for breeders. The development of SNP chips brings an immense advanced for rapid and comprehensive analysis of the genome, which is of great importance for the successful selection and Genomic selection in sheep concentrated on all aspects of genetic and production directions. However, it should be noted that genomic selections in sheep breeding, and especially in goat breeding, take place at a slower pace compared to cattle breeding.

“…The application of DNA technology is becoming a tremendous challenge for the farm breeding of domestic animals (Caro Petrović et al, 2021). The traditional methods of selection and genotype selection can increase the efficacy of improving both the livestock of an individual farm and the breed as a whole (Gorlov et al, 2021).…”

“…Morphometric traits and growth intensity were also analyzed previously for different local sheep breeds reared in a small area of Albania (Hoda et al, 2022;Hysi et al, 2023). DNA analysis has great practical application in farm management (Caro Petrović et al, 2021). Selection based on genetic markers for productivity traits such as weight gain and meat quality consist of working with animals with high genetic potential (Bozhilova et al, 2020).…”
