A single nucleotide polymorphism in CAST gene is associated with meat quality traits in rabbits
Journal Title: Animal Science Papers and Reports - Year 2016, Vol 34, Issue 3
Abstract
The purpose of this research was to investigate the effect of the Calpastatin (CAST) gene on meat quality traits in the Hyla, Champagne and Tianfu Black rabbit breeds. We detected one single nucleotide polymorphism (SNP: g.16443397 T>G) located at 271bp in intron 8 in the Hyla, Champagne and Tianfu Black rabbit breeds. This SNP was significantly related to pH and intramuscular fat in rabbit meat from the longissimus dorsi and biceps femoris muscles. Rabbits with the GG and TT genotypes had lower pH and intramuscular fat content than GT rabbits. A comparison of meat quality trait least squares means for the longissimus dorsi and biceps femoris muscles indicated that pH values were similar in both longissimus dorsi and biceps femoris muscles, color lightness in the biceps femoris muscle was higher than that in m. longissimus dorsi, while color redness and yellowness in m. longissimus dorsi were higher than in the biceps femoris muscle. Thus, results reported here indicated that this CAST SNP may be of potential use in marker assisted selection for meat quality traits in rabbits.
