Abstract
It is current practice to mate sows at least twice at their first oestrus after weaning. Recently, it has been suggested that mating sows only once may reduce costs without affecting performance. However, the scientific validity of the data on which this claim is based is open to debate. In this experiment, we investigated the effect on reproductive performance of single vs double mating, using planned comparisons, made under well controlled conditions, with adequate numbers of animals. The AUSPIG simulation model was used to estimate the impact of mating strategy on profitability.
