This calculation assumes that:
- The same income is obtained for each parity.
- In the last parity the cull value of the sow is added to the income for that parity
- If the last parity is incomplete, the income is the fraction of income attributable to that parity.
For example, a parity of 5.5 has:
- Five complete parities with full income.
- The sixth parity is incomplete with an income calculated as (0.5 * expected income per parity).
