Why should sows be fed less in the days before farrowing? Cause analysis
Why should sows be fed less in the days before farrowing
Asking the experts: I have read a lot of material saying that sows should be fed less in the days before farrowing. Why? What are the benefits of reducing feed? If feed is not reduced, what problems will arise?

1. It reduces the burden on the gastrointestinal tract, so that the blood supply is directed mainly to the reproductive system, which helps farrowing and postpartum recovery
2. It helps the sow increase feed intake after farrowing
3. It reduces pressure from the gastrointestinal tract on the birth canal and prevents dystocia

Thanks for the reply above! If it is to reduce the burden on the gastrointestinal tract, why not just reduce feed by half only on the day before the expected farrowing date? On the day of farrowing, pigs generally do not eat much anyway.

The most important thing is preventing dystocia

Also, it is to prevent postpartum paralysis in sows,

If the time is too short, it cannot produce the proper effect!!

Thank you for your reply. I would like to ask further, could you explain the reason?
---------------------
There is no such saying; I only reduce feed for the fat ones!

After a sow farrows, a large amount of blood calcium is excreted into the colostrum with lactation. At the same time, estrogen secretion increases during farrowing, which reduces the absorption of calcium from feed, and blood calcium drops rapidly, causing the sow to have difficulty standing and become paralyzed. Reducing feed intake can stimulate the sow to secrete calcitonin and increase blood calcium concentration
