Abstract Background: The previous study in our team found that supplementation of probiotic Bacillus amyloliquefaciens SC06 (BaSC06) as an alternative to antibiotics (Kitasamycin) can effectively reduce the diarrhea rate and promote the growth performance of weaned piglets. We speculate that BaSC06 may become a better substitute for antibiotics for fattening pigs. Hence, the objective of the present study is to evaluate the effects of BaSC06 substitute antibiotics on growth performance, digestive functions, antioxidant capacity, macrophage polarization and intestinal microbiota of fattening pigs. Methods: A total of 117 fattening pigs with similar weight and genetic basis were selected and divided into three groups: Anti group, fed with basal diet supplemented with 40 g/t Kitasamycin; Anti + Ba group, fed with 1 × 108 CFU/kg BaSC06 and 20 g/t Kitasamycin; Ba group, fed with 1 × 108 CFU/kg BaSC06 replaced Kitasamycin. Each treatment had three replications of 13 pigs per pen. Results: It indicated that BaSC06 replacement significantly improved ADFI and ADG in fattening pigs. It also improved intestinal digestion and absorption function with the increased activities of intestinal digestive enzymes and higher expression of glucose transporters SGLT1 and small peptide transporters PEPT1, maintained intestinal integrity significantly. Besides, supplementation with BaSC06 enhanced intestinal and body antioxidant capacity by activating Nrf2/ Keap1 antioxidant signaling pathway. In addition, BaSC06 as a substitute could alleviate intestinal inflammation by inhibiting the production of pro-inflammatory cytokines and chemokine and simultaneously increase the expression of M1 and M2 macrophage marker proteins in the intestinal mucosa. The transcription factor STAT3 regulated M2 polarization, which maintained immune homeostasis and reduced inflammation. What’s more, BaSC06 could improve the composition of the microbiota as well by increasing the proportion of Firmicutes, and reducing the proportion of Bacteroidetes and Proteobacteria. Conclusions: Taken together, our findings indicated that diet supplementation with BaSC06 instead of antibiotics increased the growth performance of piglets by improving the digestion and absorption of nutrients, intestinal microbiota composition and mucosal structure, antioxidative capacity and immune functions (including increasing M1and M2 polarization of macrophage).

Tea tree oil (TTO) exerts key roles in improving growth performance of pigs. However, knowledge is limited regarding comparative effects of Encp TTO and Un-encp TTO supplementation on growth performance of pigs. A study determined the effects of TTO or its capsulation on growth performance, antioxidant capacity, and intestinal microbiome of weaned pigs. A total of 144 healthy pigs (8.5 ± 0.24 kg) were subjected to four treatments for a 28-d trial with six replicates per treatment and six pigs per pen: negative control, NC; positive control, PC (antibiotic supplemented); Un-encp TTO (supplemented with unencapsulated TTO); Encp TTO (supplemented with encapsulated TTO). NC, TTO, and PC treatments were compared with regard to improved average daily gain (ADG), average daily feed intake (ADFI), feed conversion rate, nutrient digestibility, and intestinal morphology (p < 0.05) and decreased diarrhea rate. TTO- and PC-treated pigs had higher levels of serum superoxide dismutase, glutathione peroxidase, and immunoglobulin G; lower levels of liver aspartate aminotransferase and alanine aminotransferase; and improved concentrations of interleukin 10 (IL-10), tumor necrosis factor α, and IL-1β (p < 0.05). TTO- and PC-treated pigs had higher abundance of beneficial bacterial species Subdoligranulum and lower abundance of diarrhea associated species Escherichia–Shigella in cecal and colonic digesta (p < 0.05). Encapsulation of TTO preserved more activities of TTO than its unencapsulated counterpart by showing higher ADG, ADFI, and feed conversion rate during day 1 (d1) to d14 (p < 0.05) and tended to lower diarrhea rate (p = 0.083) and improve villous height/crypt depth (VH/CD) ratio (p = 0.089) in jejunum. Encapsulation of TTO also improved antioxidant indexes and decreased liver injury and inflammation accordingly (p < 0.05). Encapsulated TTO-treated pigs had higher abundance of beneficial Clostridium_sensu_stricto_1 and lower the abundance of harmful Escherichia–Shigella in cecal and colonic digesta (p < 0.05). Our results demonstrated TTO benefits on improving growth performance of weaned pigs and further proved that encapsulation of TTO was superior to its unencapsulated counterpart at multiples. Encapsulated TTO was similar to the PC group and could be potentially an alternative of feed antibiotics for weaned pigs.
