Probiotics is a valid biocides, added to feed, protect the intestinal health of aquaculture to enhance immunity was having the effect of disease prevention, promote growth and improve the current deposit rate of growth of benefits. The manufacturing process of extruded pellet requires high temperature and pressure. Probiotics are not resistant to high temperature and pressure and cannot be added in the process. At present, the probiotics can only be mixed and adsorbed on the surface of the feed before feeding. It is time-consuming and laborious, easy to dissolve and lose. Developed probiotic oil/water emulsification after coating technology, saving the time of mixing probiotics, reducing the loss of probiotics and facilitating feeding . Establish a field for white shrimp and measuring regularly sample to evaluate the effect of feeding healthy feed by weight gain rate, feed efficiency, and survival rate.
