Abstract: Very Low Density apolipoprotein-II (apoVLDL-II) is a major constituent of Very Low Density Lipoprotein (VLDL) and is involved in lipid transportation in bird species. The current study was designed to investigate the associations of an apoVLDL-II gene intron-1 polymorphism on duck meat quality and fatness traits. The results showed that there were two alleles (A and B) and three genotypes (AA, AB and BB) in the experimental populations. AA genotype and A allele frequency were highest. Eight SNPs (T667C, C669G, T673C, G674A, G683A, G688A, C708G and T715G) and inserted/deleted GT after position 764 bp were found by sequencing. The apoVLDL-II gene intron-1 polymorphism was associated with multiple traits of meat quality and fatness in the 170 individuals, including pH-value, tenderness, water holding capacity, IMF, serum total cholesterol, serum triglyceride and abdominal fat. This research suggests that apoVLDL-II intron-1 has broad effects on meat quality and fatness traits in duck.
