Could you tell me how to deal with the birth weight of piglets?

The basic breed of piglets is more than 5 jin, and sows are often difficult to give birth. How to deal with it? ,-C-section! Hehe, the key is to give birth every time, which is very troublesome But the pig is reluctant to deal with these good motherhood-appropriate food restrictions for sows in the third trimester of pregnancy-preferably restricted, and the intake of lactation food is postponed by about 5 days. -- Food restriction.-- you raise really well. -Food restriction is a good choice-- hehe Thank you-- yes, more than 5 jin-- your sow hero, giving birth to such a strong baby. -- I'm also afraid that it will be too annoying and suffocate too much, so I'm also limited to materials now.
