To be frank, I got rather emotional. But, there again, that is the reality of farming.
I totally respect their feelings for their pigs and watching people going through such genuine grief is rough. That's the part I had to fast forward through.
Just as another data point, there's a couple on Youtube that I'm subscribed to, (I'll link to them below), they got some of the exact same breed of pigs at about the same time.
The breeding sow they got had a litter of ten the previous year and all piglets did well, as had her previous four litters.
This time, there were seven still births and three that survived (although it seemed to be touch and go for one of them).
Some people say that farrowing cages are required, however, this couple had a large farrowing area for the sow and then a separate area (called a "creep area") barred off which had a heat lamp that the piglets are attracted to.
