What are the network stalks for postpartum nursing of sows?

This is a funny network stalk in a sketch.

This stalk comes from the essay Heart Disease and Postpartum Care of Sows. This stem originated from Zhao Benshan, Fan Wei and Gao Xiumin's essay Heart Disease. The first book used by Dr. Zhao Benshan in his essay was called Postpartum Care of Sows, but before I had time to talk deeply, I found that it was not a professional psychotherapy book, so I put it down, but the name of this book has become a famous online joke and began to spread gradually.

In the essay Heart Disease, Zhao Benshan has a line: The first topic is postpartum care of sows. The audience burst into laughter as soon as this line was said. After that, the postpartum care of sows has become a stalk, which is very funny for ordinary people. This is a joke. But in fact, for pig farmers, postpartum care of sows is very important.

Characteristics of postpartum nursing for sows;

Sows are very important resources in pig farms because they bear the heavy responsibility of breeding and nursing piglets. Without sows, pig farms will have no profit, and there will be no meat for fattening pigs. If you want to raise a good sow, you must do a good job of postpartum care, so as to prolong the service life of sows and ensure the health and safety of postpartum sows and piglets.
