The present study explored polymorphism in ACSL1 gene, a candidate gene involved in fatty acid metabolism and milk fat synthesis, in thirty lactating Red Kandhari cattle. Two reported SNP regions, g.35446C>T and g.35941G>A, were targeted for genotyping. The polymerase chain reaction for SNP g.35446C>T, and g.35941G>A yielded PCR amplicon of 148 and 142 bp, respectively. SSCP analysis revealed no mobility variation, and subsequent Sanger sequencing confirmed monomorphic patterns with homozygous CC and GG genotypes, respectively. These findings indicated that the selected ACSL1 regions are conserved in this indigenous breed. Although milk trait data—including fat percentage, protein percentage, lactose, solid-not-fat, somatic cell score, and milk yield—were collected, the absence of polymorphism precluded genotype phenotype association analysis. Documenting monomorphic loci is scientifically relevant as it establishes a genetic baseline for Red Kandhari cattle and contributes to the broader understanding of breed-specific genetic diversity. This study represents the first report of ACSL1 gene monomorphism in Red Kandhari cattle. The lack of polymorphism limited association analysis with milk traits and the results underscore the importance of expanding genetic studies to include additional SNPs, larger populations, and comparative analyses across breeds.
