Pet pigs have the same reproductive parameters as commercial pigs. The length of gestation is 114 days with a normal variation of 2 days. The breeding cycles occur all year round, with oestrus occurring every 21 days with a variation of 1 day. Pet pigs normally have about six piglets in a litter (Fig. 1.27). It should be stressed to pet pig owners that breeding is a specialized affair and should not be carried out by amateurs. Castration should be advised at an early age unless the pigs are going for slaughter.
