Polymorphisms in CTSD Gene and Associations with Carcass and Meat Quality Traits in Cattle
摘要
Abstract
4 exons of CTSD gene from 51 Simmental×Luxi catties were amplified and sequenced. 4 SNPs were identified at position 581,599,861 and 1128 bp of CTSD gene(NM 001166521. 1) by sequencing. The effects of 4 mutations on meat quality and carcass traits were analyzed by using general linear model. The results showed that T581C polymorphism significantly associated with marbling trait(P<0. 05). Genotype of BB had better marbling grade than AA and AB genotypes. Thus T581C might be a good marker for marbling traits.关键词
