To maximise the level of performance in our farm, we have to reduce the
farrowing interval as much as possible. For that, the wean to mating
period (WMP) has to be reduced. To prove that synthetic boar pheromones
aid the stimulation and detection of oestrus, 55 sows were recruited
into a field study.
Two different oestrous detection treatments were followed after 21 days
of lactation. For 37 treatment sows, synthetic boar pheromone (Servistim
) was applied each day after weaning, while the other 18 sows underwent
a daily boar exposure. The number of sows that showed oestrous signs,
respect to the dates in which it happened, were different between the
two treatments (Table 1).

The WMP was shorter for treatment sows with Servistim compare to the other treatment. Therefore, we can say that the use of boar pheromones aids to optimise the mating management in the farm, to reduce the number of boars and to improve the reproductive efficiency of sows, since the unproductive days are reduced, stimulating the onset of oestrous in the sow
