What is leech breeding technology?

Leech, also known as leech, has been a precious medicinal material since ancient times. Can be used for treating angina pectoris, apoplexy and traumatic injury.

Put fresh blood clots of pigs and cows by the pool at 5 ~ 6 pm, and half of the blood clots are immersed in water and half are left on the shore, which can attract medical leeches to eat and prevent water pollution. The residual blood clots should be removed in time to prevent pollution caused by mildew and deterioration. Feed it every 5 days.

When water pollution stinks, change the water in time. When changing water, do not change water in large quantities or in whole, in case the temperature difference changes greatly, which will affect the digestive ability of medical leeches or cause other diseases. Gradually change a small amount of water, first release a small amount of old water, and then inject a small amount of clear water.
