Effects of Solid-State Fermented Feed of Lactobacillus Amylovorus TZR-PI001 on Growth Performance, Antioxidant Performance and Fecal Microflora of Pigs

China is a big country of pork consumption, and people's demand for pork is higher and higher. However, the prohibition of antibiotics in feed has led to the decline of pig growth performance. Therefore, it is urgent to find an alternative feed antibiotics. The existence of anti nutritional factors in the diet will lead to the decline of feed utilization. After microbial fermentation, feed can reduce the level of anti nutritional factors and improve the nutritional value of feed. At the same time, microbial metabolites are beneficial to animal health. The purpose of this study was to clarify the prebiotic mechanism and resistance of Lactobacillus amylovorus TZR-PI001 in vitro, the effect of solid-state fermentation on the nutritional value of full price mixed feed for growing pigs, and the effect of the fermented feed on the growth performance and fecal microflora of growing pigs.
