The use of genetic markers in swine. I. Reproductive and disease resistance traits

Abstract

In the last two decades, the genomic genetic in domestic animals has been the target of intensive studies to clarify questions concerning molecular structure, regulation and expression of genes. Certainly, new opportunities to increase animal productivity, performance, reproductive rates, food efficiency, carcass quality, health and well-being are expected. Currently, more than 1,800 genes and markers are mapped in swine. In this context, determination of informative DNA sequences and development of new techniques to monitoring these sequences are important. The association of molecular and quantitative genetics, will allow the use of introgression and marker assisted selection. Considering that reproduction and sanitation are primordial to the success of the production systems, these biotechnologies could generate benefits to all productive pork chain segments.
