Abstract

The invention provides a molecular genetic marker for pig remaining feed intake characters and application. By identifying the molecular marker ALGA0093815 affecting the boar remaining feed intake, the marker for different genetic boar remaining feed intakes has great remarkable differences, on the basis of related analysis of the boar remaining feed intake and full-genome molecular genetic marker, the large-effect molecular genetic marker affecting the pig remaining feed intake is successfully screened out, the screened genetic marker can be verified by Du grown pig groups, the feed consumption in the production process can be effectively lowered, the homozygous pig with the low remaining feed intake can be selected, the feed consumption in the production process can be effectively lowered, the boar raising production cost is lowered, enterprise economic benefits and competitiveness are improved, the breeding progress of a high feed utilizing efficiency strain is accelerated, by selecting and remaining TT pure pig to enter the core group, the remaining feed intake is lowered, and the feed consumption and breeding cost are effectively lowered.

Description

technical field [0001] The disclosure relates to the technical field of pig genetics, in particular to molecular genetic markers and applications of pig residual feed intake traits. 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( 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 intake (Ave...
