Analysis of Pigs Population Genetic Structure on H-FABP Gene Responsible for Intramuscular Fat Contents

Abstract

DNA diagnostics in pigs breeding let us do directed rearing of preferred genotypes that accelerates pigs breeding on its reproductive, fattening and meat qualities. Proteins complex that connects fat acids (H-FABP), accumulated in heart and skeletal muscles, is responsible for intracellular fat acids transportation, plays onу of the key roles in lipid exchange and is considered to be one of the main candidate as a meat quality marker. Allele variants of H-FABP, having pleiotropic effect, influence greatly at a number of valuable traits, such as fat thickness, intramuscular fat contents (determines meat quality) etc. As a result of researches it was stated that preferable from breeding point of view is H-FABP^ddHH genotype. Authentic association of allele variants ddHH and DdHH of H-FABP gene is shown with such parameters as lion and fat thickness, live weight growth etc.
