All three halothane genotypes were found in the Landrace breeding herds and the frequency of homozygote (NN) was highest. The reproductive performance traits of Landraces pig of halothane genotypes were tabulated and discussed in the present study. The results indicated that homozygote halothane stable boars (NN) have got higher total forward sperms and homozygote halothane-resistance sows (NN) have got bigger litter sizes and weigh at birth, 21st day and weaning compared with the heterozygote (Nn)
