Present study revealed the heritability of growth traits and reproductive traits for bringing improvement in livestock productivity. The success of bringing improvement can only be predicted if we know the degree of correspondence between phenotypic value and the breeding value of an animal. Heritability is the fraction of the observed phenotypic variance with result from difference in hereditary among the gene and gene combination of the individual. The broad concept of heritability in which the hereditary variance is consider as the sum of the additive genetic variance, dominant deviation and epistasis. Heritability estimate of growth traits body weight at different ages had low to moderate and some where higher at different ages. The heritability estimate of reproductive traits like age at first farrowing was greater than unity in all of the genetic group. Litter size at birth and at weaning had low to medium heritability in majority of the cases. The estimate of heritability for litter weight at birth and at weaning was low for LR X D, desi and medium for Landrace and data pooled over all genetic group. In general heritability of farrowing interval was moderate in nature.
