The wild boar lives in a family party that has a territory of 10 - 20 sq km but in the autumn, family groups come together to form herds of up to 50 females and youngsters. 



Wild boars are sexually mature at 18 months of age, but a male will not usually mate until he is about four years old. During the autumn mating season, the male joins a herd of females and fights any male who challenges his position. Fighting boars use their tusks to slash at each other's shoulders. Despite their thick skin and coarse layer of hair on the shoulders, deep wounds are sometimes inflicted. After mating, the boar leaves the herd, taking no part in rearing the young.

After a gestation period of 112 - 115 days a litter of 3 - 12 piglets is born in the spring. The sow prepares for the birth by constructing a nest of grass and the babies are born into this. The mother has 8 - 14 teats and each piglet has its own teat from which to suckle. The first piglets born choose a teat near their mother's head so that they have a better chance of attracting her attention and are less likely to be trodden on. The piglets are born with stripes and these help to camouflage them in the undergrowth. The litter stays in the nest for about 10 days and then the family moves off, joining up with previous litters. The young are suckled for about 12 weeks before they are completely weaned onto food which they find while rooting around with their mother. Their coats become a dull, dun colour at about 6 months and they will stay with their mother until at least the next litter is born. At one year old their coats are a rich black-brown and they reach full size at 5 - 6 years of age.
