1. What is the level of development of porcine artificial insemination at this stage? What are the gaps between the developed countries in China and other pig artificial insemination technologies?

The use of Yi-Ji-Yi bio-fermentation agent fermented good water must be sealed, as long as the seal is good, can be stored for six months will not degenerate. After feeding, the fermentation tank (cylinder, barrel) shall be cleaned and sterilized immediately; the fermentation station shall be cleaned and disinfected after each fermentation operation to prevent the growth of pathogens.

Precautions:

1, as far as possible to fill the container, do not leave the air inside, (this is to isolate the air, maintain anaerobic state, prevent harmful bacteria use the oxygen in the air to grow and reproduce, kill all kinds of harmful germs with drowning), Then cover it with a plastic film and firmly tie it with a rubber rope. It does not have to be tightly sealed, leaving a small amount of air to prevent the large amount of gas produced during the fermentation process from causing a transitional expansion and even an explosion. For fermentation, as long as it is fermented for 1 to 3 days, some bubbles appear in the material at the beginning. This is the result of normal fermentation. Afterwards, the PH acidity increases a little to produce some koji aromas that can be fed to pigs.

2. Before the fermentation, it is not necessary to remove the hard materials such as toothpicks, long fishbone, glass, and plastic bags in the gills of water (too odor). Before the fermentation is completed, the spoils must be taken out before feeding the sprinkling materials. The object is singled out, otherwise it is eaten by the pig and it will scratch the intestine and cannot be discharged, causing inflammation, fever or even death.) The bones and raw meat in the muddy water do not need to be pulled out. The direct mixing and fermentation can be used. The fermentation material must be prepared with meat and vegetables. This means that certain food materials must be included, such as rice and porridge, to facilitate the growth of the strains. If it is a pure hot pot, it cannot guarantee the success of the fermentation. We must add some energy materials such as rice and corn.
