【 摘 要 】

This study aims to determine the polymorphism of Prolactin (PRL | XbaI and PRL | DraI) genes in Bayang ducks using the PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) technique and its association with weight of ducks aged 1-10 weeks. This study used 200 Bayang duck blood samples consisting of 102 male ducks () and 98 female ducks (). DNA from blood samples was isolated using the Genomic DNA Purifification Kit (Promega) using protocol from the manucfacture. The DNA was then amplified using two primers with F: 5′-AAA TTC CCT CTC ACA GTT ACA-3′ and R: 5′-GAT GCA GAG ACA AGT TTC ACC-3′ and F: 5′-GAATAGAACACTTGACCCTG-3′ and R: 5′-TAGAGGAGGCAAGCATAG-3′ which produces fragments with a length of 416 bp and 566 bp. Restriction with XbaI enzymes that recognized the binding site (5-TT CTAGA-3′) resulted 3 genotypes: homozygote (+/+), heterozygote (+/-) and homozygote (-/-) with frequencies 0.455, 0.495 and 0.050 respectively and with frequency allel (+) 0.702 and frequency allel (-) 0.297. While the results of the restriction with enzyme DraI found three types of genotypes, namely (+/+), (+/-) and (-/-) with frequencies of 0.64, 0.35 and 0.01 respectively with frequency allel (+) 0.82 and allele frequencies (-) 0.18. From the results of the analysis, it was found that there was no relationship between these two diversity and weight ducks of duck.
