At what age does pig get pregnant?
The female pig (sow) is ready to breed (reaches puberty) at 5 months of age and will show signs of being in heat. Some slow growing types and animals which are underfed will be older when they reach puberty. The sow will come into heat every 3 weeks throughout the year if she is not mated.
What happens to the last two pigs born in a litter?
However, the intervals are longer between the first two and the last two pigs born in a litter. Generally speaking the last pig born has less than a 50% chance of survival in any litter. Most piglets must leave the space they occupied during pregnancy and enter empty space previously occupied by a delivered pig.
How long does it take for a pig to Farrow after breeding?

Piglets are delivered approximately every 15 minutes.
What should litter parity be for a pig?
An average herd parity of 2.5 to 3.0, with over 45 percent of the sows in parity three to six is optimal for overall productivity. The parity distribution that optimizes litter size varies with genotype, management and facility type. 2. Genetics
