Sows with more than 16 piglets Total Born (TB) per litter have twice as many stillbirths (SB) as those with 13 to 16 TB litters, and three times more SB than sows farrowing litters smaller than 13 TB.

This article discusses 4-week batch farrowing (4WBF), very common in small farms (250 sows) in some other countries, including France. Analysis will be based on a comparison with 3-week batch farrowing (3WBF).
This second part deals with the problems caused by not recording properly the cause of abortions, sows and piglets deaths, nurse sows and hormonal treatments.
This first part deals with backward and impossible data, i.e. the sows that are no longer in the farm but still appear both in the management softwatre and the 100% delivery rates in gilts.
The number of sows that suffer some kind of leg injury is much higher than is apparent, and even more so in second farrowings.
Apparently, lameness problems amount to just 5% of the causes for sending pigs to slaughter...
We can predict a sow's production based on the number of piglets born alive at first farrowing. In addition, the best sows' performance will outdo the others' continuously.
