Assessment of genetic variability in Kangayam breed of cattle in Tamilnadu, South India was carried out using 25 bovine microsatellite markers. The mean number of alleles was 4.04 ± 0.09 with a range of 2 to 6 and the allele size ranged from 94 to 300 bp. The frequency distribution of alleles in the breed was from 0.0104 to 0.9167. The estimated heterozygosity was 0.6183 ± 0.01 and the PIC was 0.5628 ± 0.03. The overall mean within-population inbreeding estimate (FIS) value (– 0.084) suggested excess of heterozygotes in the population. In addition, higher PIC value indicated the scope for maintaining variation in the population and strategies to take meaningful conservation.
