Answer:
10
Explanation:
The pigs tend to have very large litters. A sow that has been fed and kept well usually has around 10 piglets per litter. While 10 piglets are somewhat the normal number, there are many cases when a sow has produced 15 or 20 piglets per litter. Not just that the liters are very large, but a sow can produce not one, but two litters per year, making it an animal that has extremely quick reproductive cycle for its size. The gestation period is also not long for the size of these animals, and it usually lasts between 112 and 120 days. When the piglets are born they are very small and helpless at first, but they manage to grow and mature very quickly, reaching sexual maturity at only between 3 and 12 months of age, thus becoming adults in a very short time span.
It should be based on the principles of immunology to understand this phenomenon: the immune system produces antibodies against an antigen that it does not possess
