Abstract: The objective of the present study was to detect the Single Nucleotide Polymorphism (SNP) of Dopamine Receptor D4 (DRD4) gene from 143 horses. We observed C of 147th base→T substitution and A of 292th base→G substitution SNP in 15 individuals from 143 horses. In C→T substitution case, SNP was observed from 7 individuals, among them 5 individuals of 7 horses were evaluated to be wild and fierce in temper generally by horse management supervisor and veterinarian and 2 individuals from 8 horses observed A→G substitution were evaluated to have wild and fierce character in common. The SNP of DRD4 gene was observed by 23.3% (7 individuals from 30 horses) from wild and fierce character ones and 7.1% (8 individuals from 113 horses) from mild temper ones which result in little SNP detection among most mild temper ones.
