A weaned piglet is a non-suckling piglet from the stage of weaning to the age of 10 weeks and is mainly characterized in that ① weaning stress is expressed by that liquid breast milk is taken as a main feed, dyspepsia diarrhea is easily generated, ② needs to adapt to a new living environment, a home delivery room is changed into a breeding house and is accompanied with grouping and grouping again, ③ environment is changed, diseases are easily generated, ④ weaned piglets grow and develop quickly, the demand on nutrients and energy is large, but the function of digestive organs is still incomplete, therefore, the improvement of feed digestibility is a key factor for determining the success rate of weaned piglet feeding, and the control of survival rate, diarrhea rate and improvement of production performance are important indexes for determining the feeding benefit of the piglets.

The high-quality feed raw materials of domestic pigs such as corn, bean pulp, fish meal and the like are very short-cut, the bean pulp is mainly derived from imported soybeans, the dependency degree on import reaches more than 75%, the dependency degree on import of the fish meal reaches more than 70%, and the feeding corn accounts for more than 63% of the total corn yield in China, so that the gap is large. In addition, the compound feed for weaned piglets mainly takes corn-soybean meal-fish meal type as the main feed in China, and is under the market challenge and impact under the conditions that the prices of corn, soybean meal and fish meal are high and the profit margin of feed products is reduced.
