Another thing which is a huge help getting the timing of AI right is to use Boarmate spray on the main day you think they are on heat - ie. swollen vulvas, responding to stimulation, standing or nearly standing still, weird behaviour and manically active ears (particularly Tamworths). A spot of mucus on or just inside the vulva is an even better sign. If they are up for it, they respond very noticeably to the spray, either freezing there and then, or showing you excessive attention as if you were the boar. (At other times when they are not ready for mating they are completely disinterested in the spray.) We always AI not at feeding time, as they are far too busy rooting around for every last nut, and usually wait for an hour or so when they are no longer hungry and not obsessed with eating. When you have got the timing just right and spray the Boarmate near their nose, they stand stock still for 10 minutes, like a frozen statue out of Chronicles of Narnia, and do not move a muscle while you are doing the AI, even with very little back pressure. We always do the three doses, am/pm/am, or pm/am/pm, the first as soon as they respond positively to Boarmate, and often find that by dose 3 they are starting to lose interest and cannot be persuaded to stand still for very long. So far we have done AI four times and have had four first go successes. The instructions that come with the Deerpark semen are excellent, and each time we have had a bit of leakage at the end - so obviously this does not affect the end result. You can get Boarmate spray from Animal Health, address on internet. We try not to overuse the spray so they don't get too over familiar with it. HTH Tamsaddle
