  • The gestation period for pigs is approximately 114 days.

  • Pigs farrow litter sizes average from 10 to 12 piglets.

  • The average birth weight per piglet is approximately 0.9 - 2kg.

  • Young pigs are introduced to regular pig feed at 10 – 12 days of age.



  • Pigs are generally weaned at three to four weeks of age.
