In many respects, the significance of the reproductive cycle in the pig differs from that of other domestic animals. Unlike the cow or the eve, the sow owes her value solely to her ability to produce and rear many young. The more young she can produce which are viable to marketable age, the greater her value. The ideal sow is defined as the one which begins to breed as early as is compatible with her future productivity, continues to breed as often as possible for as long a life as possible, and produces large litters of healthy pigs rearing them to good weaning weight without loss. In brief, fertility, fecundity, mothering ability and milk yield must all be high.
