Abstract

Abstract: The new dam line (D VI) in Chinese lean type pigs, which was formed by reciprocal cross breeding among famous breeds like Taihu, Landrace and Seghers. Through six generations selection, the multiparious sows had an average litter size above 13, average daily gain 665g, and 59.32% lean meat percentage with good quality of muscles during fattening. The multiparious sows of D VI mated with Large White , Duroc or Pietrain, and the lean meat yield per litter reached 462 kg, 470 kg or 492 kg respectively.

Key words: Pigs, Breeding, Cross Utilization, New Dam Line (D VI)
