Background

China is the first world producing country of big live pigs and a pork consuming country, annual average live pigs are 7 hundred million pigs, the annual average pork consumption is 5500 ten thousand tons, and the output value exceeds 11000 million yuan. The pig industry in China is particularly huge in size, long in industrial chain, numerous in practitioners, and related to national economy, meanwhile, pork consumption accounts for 65% of meat consumption in China, pork is related to vegetable baskets of thousands of households, and health, harmony and happiness of each' home!

With the improvement of the living standard of people, the safety on the tongue tip becomes a focus of attention of people, the quality and the safety of pork of the people are more and more 'rejected', the problem of using antibiotics in the breeding process of live pigs is suffered by mass scaling, the antibiotics are used less or even not used, the harm of antibiotic residue to the environment and human bodies is reduced or eliminated, and the method is a good wish of people. Therefore, the country has set a time schedule for forcibly quitting the feed link by antibiotics, China completely forbids adding antibiotics in the feed in 2020, and how to deal with severe stress reactions of the pigs, such as diarrhea and the like caused by intestinal dysfunction, under the condition that the feed is forbidden to resist, and the maintenance of the health of the pig intestinal to ensure the production performance of the pig intestinal is a great challenge in the live pig industry of China.

Therefore, how to provide an antibiotic-free pig intestinal function regulator becomes the research direction of our research.
