• The blood sample from 60 Damani does were collected and genomic DNA was extracted, and DNA integrity were investigated. A 447 bp promoter fragment of the GDF9 gene was amplified and Sanger sequenced for the identification of GDF9 gene polymorphism. Three novel SNPs were identified at positions g. 97(T > A), g. 142 (G > G) and g. 313(C > T) in the promoter region of the caprine GDF9 gene which significantly (P < 0.05) influenced litter size, body measurement, and milk production traits in Damani goats. The genotype CT of SNP1 significantly (P < 0.05) improved litter size, genotype GG of SNP2 significantly (P < 0.05) enhanced milk production, while the genotypes CC of SNP3 significant (P < 0.05) increased body measurement traits in Damani goats. Moreover, in SNP1 loss of 3 transcription factors (TF) binding sites occurred, SNP2 caused loss of two TFs binding sites, and SNP3 caused loss of a single TF binding site. Similarly, SNP1 and SNP2 caused the gain of three new potential TF binding sites, and SNP3 caused gain of two new TF binding sites. It is concluded that caprine GDF9 gene could be used as a candidate gene for litter size, milk production and body measurement traits in Damani goats through marker-assisted selection for future breeding program.
