1. Causes of mummified fetuses, stillbirths and abortions: (1) Poor egg quality or failure to breed at the right time causes the eggs to age prematurely; although fertilization may still barely occur, the embryos cannot develop normally and eventually die and are resorbed by the sow. (2) The feed for pregnant sows is not nutritionally complete

Causes and Solutions of Diarrhea in Early-Weaned Piglets
The causes of post-weaning diarrhea in piglets are complex. Research over the past 20 years has shown that dietary factors are the main cause of post-weaning diarrhea in piglets. The reasons are: (1) A certain number of pathogenic microorganisms (pathogenic Escherichia coli and rotavirus, etc.) generally exist in the gastrointestinal tract of healthy piglets. (2) Introducing isolated pathogenic microorganisms into the gastrointestinal tract of unweaned piglets and weaned piglets that are either not supplemented or fully supplemented with feed did not always cause diarrhea. (3) The proliferation of intestinal pathogenic microorganisms is not necessarily linked to post-weaning diarrhea. (4) When no pathogenic microorganisms are present or proliferating, weaned piglets can still develop diarrhea. (5) If weaning does not cause intestinal damage, piglets will not develop diarrhea, although pathogenic Escherichia coli can still be detected in piglet feces. (6) Practice has proven that antibiotics are not completely effective in preventing and treating post-weaning diarrhea in piglets.
