The native pigs of North Eastern region have unique traits such as early sexual maturity and quality bristles compared with exotic/ crossbreds. An attempt was made to measure the genetic variation available within Niang Megha and Tenyi Vo pigs using 22 FAO-ISAG microsatellite markers. The analysis of microsatellite data revealed average number of observed alleles as 6.95±0.54 (Niang Megha) and 7.18±0.45 (Tenyi Vo) where as the effective average number of alleles were 3.55±0.33 and 3.81±0.41, respectively. The mean observed heterozygosities were found to be 0.61± 0.04 and 0.68± 0.05, whereas expected values were 0.67±0.03 and 0.69±0.03, for Niang Megha and Tenyi Vo pigs, respectively. Abundant genetic variations were displayed within the native pigs with the PIC values ranged between 0.41 (Sw2008) to 0.86. (S0218) for Niang Megha and between 0.45 (S0026) to 0.88 (S0005) in Tenyi Vo pigs. The mean F value was 0.15±0.05 in Niang Megha which is more than that found in Tevyi Vo.  There was no genetic bottleneck observed in the studied population. A total of 23 and 22 private alleles observed in Niang Megha and Tenyi Vo pigs.
