“…This SNP, in the commercial population, was associated with body weight at 42 days, eviscerated weight, leg weight, water loss of meat by drip, and lightness and redness content of meat. Our results corroborate previous report by Zhang et al (2008), that described association of different SNPs in the CAPN1 gene with body weight, leg weight, carcass weight, and breast weight.…”

“…Among the 4 reported SNPs, 3 (i.e., CAPN1 3535, CAPN1 7198, CAPN1 9950) were polymorphic; for CAPN1 2546, the C allele was fixed in the studied populations. In 8 meat-type chicken populations, including 5 purebred lines (developed from Chinese local breeds) and 3 crossbreeds, CAPN1 2546 was more polymorphic, as can be observed in Zhang et al (2008). However, this observation may be contributed more to the genetic differences between breeds.…”

ABSTRACT. The micromolar calcium-activated neutral protease gene (CAPN1) is a physiological candidate gene for meat tenderness. Four previously identified single nucleotide polymorphism (SNP) markers located within the CAPN1 gene were evaluated for their associations with variation in the meat tenderness of a Chinese indigenous chicken breed, a higher meat quality breed (i.e., Qingyuan partridge chicken), and the commercial Recessive White chicken breed. WarnerBratzler shear force measurements were used to determine tenderness phenotypes for all animals; intramuscular fat (IMF) content and rate of water loss in the breast muscles were also measured. Genotyping was performed by the polymerase chain reaction-ligase detection reaction method. Polymorphisms were identified for all markers, except CAPN1 2546. The frequency of allele T was zero, and allele C was fixed for CAPN1 2546 in the studied populations. The SNP CAPN1 3535 in the CAPN1 gene was significantly associated with tenderness and other meat quality traits, where animals inheriting the AA genotype had smaller shear force values, lower water loss rates, and higher IMF contents. Moreover, H1 (AAA) was the most advantageous haplotype for meat tenderness. The results of this study confirm some previously documented associations. Furthermore, novel associations have been 1393-1403 (2015) identified that, following validation in other populations, could be incorporated into breeding programs to improve meat quality.

“…Haplotypes provided a practical solution to resolve these problems (Daly et al 2001;Zhang et al 2008). In this study, haplotypes were constructed with the eight SNPs and were used to analyze the association of combined haplotypes with carcass traits.…”

VLDLR gene was chosen as a candidate gene infl uencing abdominal fat trait and body weight due to previous studies in human and mouse. Herein, the objectives of this study were to identify genetic polymorphisms of duck VLDLR gene, and to analyze association between combined haplotypes and abdominal fat trait in Gaoyou domestic duck. A total of 207 individuals, including the elite reservation farm Gaoyou duck (FG, n = 50), the newly formed Gaoyou duck (NG, n = 54), the reserve area Gaoyou duck (AG, n = 50), and Hybrid duck (HY, n = 53) were used for study. In this paper, one genomic fragment was sequenced in all ducks encompassing a region from exon 14 to exon 16. Five single nucleotide polymorphisms (SNPs) and three insertions/deletions (indels) were identifi ed. Based on the above eight SNPs, 11 haplotypes were identifi ed. Th e H1 was the most common haplotype in AG, FG, and HY populations, which occurred at a frequency of more than 41%. Statistical analysis indicated that four combined haplotypes were associated with body weight at 10 weeks (BW10) (P < 0.05) and abdominal fat percentage (AFP) (P < 0.01) in Gaoyou FG and AG joint population. Th is result suggested that the VLDLR gene could be a potential gene infl uencing abdominal fat trait and body weight and may be used in marker-assisted selection (MAS).
