The preceding table has been calculated on the basis of 

 113 days for the gestation period. To use the table, the

 and the date on the right will be the time due. For 

 example, if a sow is bred on November eighteenth, the 

 date to the right shows that she will be due to farrow 

 March eleventh; if bred May twelfth, she will be due 

 September second, and so on.
