The invention provides an SNP molecular genetic marker of a TPP2 gene related to remaining feed intake. Through the identification of a molecular marker MARC0030864 affecting the remaining feed intakeof boars, difference exists in the remaining feed intake of the boars of different genotypes; through the correlation analysis of the boar remaining feed intake and the whole genome molecular geneticmarker, the large effect molecular genetic marker affecting the remaining feed intake of pigs can be successfully screened; the marker can be applied to the selection of breeding pigs; feed consumption during production can be effectively reduced by selecting homozygous pigs with low remaining feed intake, so that the economic benefits and competitiveness of enterprises can be enhanced; an allelecan significantly reduce the remaining feed intake; and the selection of the breeding pigs can be assisted by detecting the genotype of the MARC0030864 marker, and a core group can be entered by selecting TT homozygous breeding pigs, so that the remaining feed intake can be reduced, and feed consumption and breeding costs can be effectively reduced as well.
Description
technical field [0001] The disclosure relates to the technical field of pig genetics, in particular to the SNP molecular genetic marker of TPP2 gene related to residual feed intake. Background technique [0002] Feed efficiency, as an important economic trait, has always been the focus of domestic and foreign pig breeding companies and breeding pig improvement companies. In the middle of the 20th century, Feed / Gain ratio (F / G) was used to study feed efficiency at home and abroad. Since two pigs with the same feed gain ratio were used to study feed efficiency, their feed intake The limitation that the amount and gain may be different (Yang Yunqing, Wang Zhongxin, Yin Bingbei. Discussion on the index selection method of ratio traits. Journal of Animal Husbandry and Veterinary Medicine, 31(3):198-202(2000)); 1963, Koch et al. (Koch R M, Swiger L A, Chambers D, etal. Efficiency of feed use in beef cattle. J Anim Sci, 22 (2): 486-494 (1963)) first proposed the residual feed inta...
