There is an increasing demand for horse milk, but the current domestic performance of the horse milk has not yet conducted a systematic in-depth study. We carried out a pilot study on 13 single nucleotide polymorphisms (SNPs) located within five genes in Kazakh horse using Kompetitive Allele Specific PCR (KASPTM). An association study with average daily milk production of 60 Kazakh mares was performed for 6/13 polymorphic SNPs. The results showed that only two SNPs rs114262445 (NUMB), rs1136347938 (CA8) out of the 6 polymorphic markers were significantly associated with milk production in Kazakh horses. These results indicate the potential of using SNPs for the NUMB and CA8 genes as candidate genes for selection and farm production outputs. This study is relevant for future horse genomic studies.
