Effects of the DMRT1 genotype on the body weight and gut microbiota in the broiler chicken.

ABSTRACT: Intestinal microbiota is a critical determinant of growth and risk of metabolic diseases. Our previous studies showed that the locus rs16775833 within the DMRT1 gene is significantly associated with variation in the population structure of the gut microbiota, which is involved in determining the BW of the chicken. To assess the accuracy of correlation of rs16775833 located in the DMRT1 gene on microbial population and BW in birds, 2 genotypes GG and TT in the rs16775833 were identified in Chinese Yellow broiler breeders. We found that BW in the TT genotype group was significantly higher than in the GG genotype group at 7 and 13 wk of age in 777 female chickens. A full-length 16S rRNA sequencing approach was used to further evaluate the fecal bacterial composition of female broilers in 11 T
