POLYMORPHIC ANALYSIS OF SOME GENES RELATED TO FERTILITY OF MONG CAI PIG PARENTS TO SERVE THE WORK OF SELECTED BREEDS.

Abstract

It is necessary to study on livestock breeds for the purpose of improving undesirable traits, maintaining and preserving the precious essential traits. In order to overcome the drawbacks of traditional selective methods, the scientists have genetically engineered applications in their research to find out the genetic instructions related to the desired traits in livestock. The study was carried out on 80 pigs in Mong Cai – Hai Phong to survey ESR gene polymorphism, BF, FUT1, RNF4 related to reproductive traits in Mong Cai pig parents; determine the frequency of alleles and gene type frequency of gene ESR, BF, FUT1 RNF4 to assess the impact of the alleles and genotypes to reproductive trait serves for selecting breeds. The research used PCR-RFLP techniques. The study found out the polymorphism of the gene ESR, BF, RNF4 and did not find the polymorphism in gene FUT1.
