To improve reproduction indices we should take into account that maximum duration of semen fecundation capacity is 24 hours, and the egg should be fecundated within 6-8 hours. We need to implement a farm management specific to the reproduction sector and to identify females in oestrus twice a day between 7 a.m. and 3 p.m. to get the first insemination 1-2 hours after a female is in oestrus, and the second insemination between 6 and 15 hours, when there are the best fecundity and prolificacy indices. For short working days, we recommend that separation of breastfeeding mothers from their piglets be done twice a week. On the ground of the management programme in the reproduction sector, we should give up the classical programme of identifying females in oestrus and of inseminating oestrus sows at intervals larger than 15-20 hours. |
