Assuming you start with only 5 pigs ( 4 sows and 1 boar), you may be able to sell only 40 pigs in the first year. This is because you may have brought in the parent stock when they were 4 months old, therefore you may have to wait another two months for the pigs to reach sexual maturity. Once the sows have been mated, it may take another 4 months for them to deliver 40 piglets. Seven days after weaning, the sows can be crossed again. They may produce another 40 piglets at the end of the year. Since it takes 6 months for pigs to reach slaughter weight, you can only sell the first batch of 40 pigs.
