The effect of boar genotype on the reproductive performance of local sows was investigated. Large White (LW) and local Mukota boars were mated to 20 sows over 3 parities and the performance of the sows and litters were compared up to weaning. Data on the gestation length, number of piglets born alive (NBA), the number of piglets born dead (NBD), number weaned and the sex ratio were recorded. The weights of the piglets were recorded within 16 hours of birth and also at weaning. No creep feeding of the piglets was done and weaning was done at 35 days of age. There were no differences in the number of services per conception and the NBD. Litter size at birth, NBA and the number of piglets that were weaned were higher in sows mated to LW boars than to indigenous boars. These findings indicate that imported boars can be used under smallholder pig production systems as they complement traits of both the local and imported breeds.
