It is easy to calculate that the sow's normal gestation period for sows during the pre-production period is 108 days to 120 days, with an average of 114 days. The method for calculating the expected date of the sow is to add the date of the breeding plus 3 months plus 3 weeks and 3 days. If the sow mating date is April 10, the expected mating period is 4+3=7 (months), 10+21 (3 weeks)+3 (days)=34 days, ie August 3.
