Role of quantitative genetic in sheep and goat breeding

Abstract

Quantitative genetic methods have a variety of applications in understanding the covariance of variations between natural and managed populations. Today, the combination of molecular or genomic selection in combination with the traditional is a very reliable method for faster, more accurate assessment of the breeding value of animals. Important features of body conformation in the meat industry and good growth performance in sheep and goats, including accelerated growth rate are of economic importance. Quantitative genetics methods aim to identify genetic variants associated with quantitative traits in order to achieve genetic improvement in growth performance. Quantitative genetics remains the most reliable tool for estimating the breeding value of domestic animals. The application of practical methods which are used to assess the phenotype, requires excellent theoretical knowledge of the genetic of animals.
