The present application relates to the field of biotechnology, and particularly relates to a SNP molecular marker related to feed conversion efficiency of Ningxiang pigs and application thereof. The molecular marker comprises SNP1 and SNP2. The SNP1 molecular marker corresponds to the 97685244th site from the 5' end of chromosome 1 of the reference genome Sus Scrofa Build11.1, and is A or G. The SNP2 molecular marker corresponds to the 97782417th site from the 5' end of chromosome 1 of the reference genome Sus Scrofa Build11.1, and is A or C. The present application obtains a molecular marker significantly related to the feed conversion efficiency of Ningxiang pigs. The present application can provide guidance for the breeding of Ningxiang pigs by using the molecular marker, and can accurately and efficiently predict the feed conversion efficiency and typing, identify and screen pigs with high feed conversion efficiency and excellent meat quality, and improve the breeding efficiency.

This invention discloses a SNP molecular marker associated with sheep muscle quality traits and its application, belonging to the field of animal husbandry breeding. This invention screened a SNP molecular marker on sheep chromosome 7 that is significantly associated with sheep muscle quality traits. Its nucleotide sequence is shown in SEQ ID NO.1, and an SNP site, rs84573658 C>T, exists on the nucleotide sequence shown in SEQ ID NO.1. Experimental results show that this SNP molecular marker is associated with sheep muscle quality (muscle fiber density and muscle fiber diameter), and the overall muscle quality of the CC genotype is superior to that of the CT and TT genotypes. Therefore, this invention provides a new SNP molecular marker for breeding sheep muscle quality. This molecular marker can accurately identify sheep muscle quality traits, laying the foundation for the selection of high-quality meat sheep.
