In our present conditions of little and middle farms increasing number, it is very important from the animal health point of view, to reduce the breeding animals circulation. The rotational crossbreed sows can become a solution for producing own replacement gilts in this kind of farms and constitutes the goal of the present study. The experiment was carried out at Romsuintest Peris among 1992-1995. The used breeds were Large White, Landrace, Synthetic Line 345 Peris, Duroc and Hampshire. The foundation breeds were those with large number of animals as LW, L and LS 345 Peris. The other two have participated like paternal breeds in some sequences. The results pointed out the scheme superiority (LW x L x D x LW) for reproductive performances (prolificacy 8.87; born alive 8.68; piglets at 21 days 8.60 and a milking ability of 46.08 Kg). For growing performance were outlined the scheme LW x L x LS 345 (life gain 450 g and a percentage of muscle tissue of 49.98 per cent) and the scheme LW x L x D x LW. The schemes with the participation of LS 345 Peris and Hampshire produced pigs with meater carcasses (51.56 per cent). The experiment results allow to recommend the rotational crosbreeding as a method for producing own replacing gilts as well as finishing pigs in little and middle farms in our country.
