There have been a couple of posts recently about what to do with sow meat, and some of the sows mentioned seemed quite young, only 2 or 3 years old. I have been wondering whether the reason for their culling was infertility, and would be interested to hear just how common this problem is. How long have you kept trying before giving up? Is there a breed element to it, or any other obvious factors? Or are they being culled for a different reason altogether?
We have just got to the end of 5 failed attempts with our 23 month old Tamworth sow, who had a perfectly normal first litter of 7 last summer and had appeared to be having heats every 3 weeks after her litter was weaned, but to no avail. Two gonadotrophin injections specifically for infertile pigs and other animals has had no effect either. It has been incredibly disappointing as this is to be our last breeding year before closing down, but she too is now destined for sausages in the near future. In our case, we have always had Saddlebacks and Tamworths, and planned always to get one of each pregnant at the same time for companionship purposes, but it is always the Saddlebacks who have always got pregnant immediately, sailed through the next 4 months without problems, farrowed without intervention and then produced gallons and gallons of milk for their babies. The three Tamworth girls have all had one problem or another, the most common seeming to be poor lactation 1 to 2 weeks after the birth, with worryingly skinny piglets all screaming for milk, compared to the Saddleback piglets in the next ark gorging themselves on a happily grunting mum.
Would be most interested to hear anyone else's stories on why you are culling young sows - Tamsaddle
