Abstract

To explore the relationship between Myf5 gene polymorphisms and production performance traits in Songliao white geese, we used the chicken Myf5 sequence to design primers and amplified part of the exon 1 sequence of the Songliao white goose Myf5 gene. Results of single-strand conformation polymorphism polymerase chain reaction analysis revealed polymorphisms of the amplified fragment, including three genotypes (AA, AB, and BB). Three varieties were dominated by allele A and were mainly expressed in AA genotypes. We also identified that the Myf5 gene has one single nucleotide change (A→G) on exon 1 at locus 1344, and another (G→C) at locus 1410. Analysis of variance showed significant differences between genotypes before slaughter in live weight, carcass weight, eviscerated weight, leg muscle weight, weight of the wings, and slaughter rate. There were no significant differences with respect to other growth and carcass traits evaluated.
