Description

technical field [0001] The invention relates to the technical field of livestock feed, in particular to an antibiotic-free compound feed for weaned piglets. Background technique [0002] The pig industry is the pillar industry of my country's animal husbandry. With the development of economy and technology, the pig industry is gradually developing in the direction of scale and standardization. In the process of breeding, when piglets are weaned, they need to face the environmental stress caused by the new environment, the nutritional stress from liquid food to solid food, and the psychological stress of Oedipus after weaning. The system has not yet matured, increasing the risk of disease in piglets after weaning. The most obvious symptom of weaning piglets is post-weaning diarrhea, which occurs in more than 90% of weaned piglets in China. [0003] At present, in various breeding factories, a large amount of antibiotics are added to feed to treat post-weaning diarrhea of ​​...

[0003] At present, in various breeding factories, a large amount of antibiotics are added to feed to treat post-weaning diarrhea of ​​piglets. However, while antibiotics kill harmful bacteria, they will also kill a large number of beneficial bacteria in the gastrointestinal tract, resulting in more gastrointestinal function. disorder, causing constipation in piglets; at the same time, large-scale use of antibiotics will serious
