Optimal ration for pigs
An optimal feed ration is one that allows your animal to gain as much weight as possible while producing as much manure as possible.
Pigs 1 to 30 days old
Animals between 1 and 30 days of age (inclusive) are considered young. They gradually and evenly increase the consumption of all types of feed - the minimum amount of each type of feed on the first day and up to the maximum amount specified in the table on the last day.
The weight gain of the animals also increases proportionally (from the minimum value on the first day to the maximum value on the last day of this age period). Provided the animals receive an optimal feed ration, the sow and boar will increase in weight from 0.1 kg on the first day to 6 kg on the last day of this age period.

|Food||Quantity on the 1st day of the period (kg/day)||Quantity on the last day of the period, (kg/day)|
Pigs between 31 and 350 days old

Provided the animals receive this optimal feed ration, sows and boars will increase their weight by 0.5 kg daily.
Pigs between 351 and 380 days old
Animals between 351 and 380 days old (inclusive) are considered old. They gradually and evenly reduce the intake of all types of feed, from the maximum amount shown in the table on day 351, to the minimum amount of each type of feed on day 380.

Animals at this age are no longer gaining weight. They can't mate, they can't exercise, they can't be turned in for meat or bacon. But if a sow has successfully mated with a boar before reaching the age of 351 days, she will bear and give birth as usual (within the total life span of the animal of 380 days).
It is helpful to remember that not only do animals at this age not gain weight, but they also do not lose weight if left hungry. Older animals can live quite well on subsistence food. You don't have to feed them to keep them alive. However, if they are not fed, they will stop producing manure and the gestation period will increase.
