Abstract
Attainment of puberty in guts isolated from boars is delayed in the summer and, while this condition is largely overridden by daily contact with the mature boar, the efficacy of boar contact for inducing puberty is also reduced in the summer (Paterson et al., 1989a,b). The basis for this and other seasonally occurring reproductive dysfunctions in pigs is unknown. In the European wild boar reproductive activity in sows decreases when day-length exceeds 12 h and the young females reach puberty in late autumn when day-length is short (Mauget, 1982). In the present study we investigated the possibility that long day-length is the seasonal factor which delays puberty in the domestic gilt.
