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.

What are the reasons tissue-cultured orchid plantlets are not good
Besides being difficult to grow, tissue-cultured orchid plantlets also have a low survival rate. The low survival rate is related to the special propagation method used for tissue-cultured plantlets: the heavy use of hormones and chemical nutrients leaves the orchid plantlets in poor physical condition, frail and unable to withstand the slightest stress, and poorly adapted to the growing environment after being taken out of the flask, so they tend to sulk, neither dying nor thriving. If they are genuine tissue-cultured orchids, the flowers they produce should be the same as before, unless the wrong goods were sent. In short, tissue-cultured plantlets in the weak-plantlet stage are generally not suitable for growing at home, because these tissue-cultured plantlets themselves have low dry-matter content, poor disease resistance, a low survival rate in home cultivation, and a long cultivation cycle; many unscrupulous traders often pass off ordinary varieties as rare varieties to make money, because tissue-cultured plantlets make it hard to distinguish the characteristics of each variety (they look basically the same); if you want to introduce rare orchid tissue-cultured plantlets, it is advisable to do so at agricultural and forestry research institutes that carry out orchid tissue culture, where quality and variety are guaranteed.
