| Summary: | This study aimed to investigate the effects of maternal glycerol monolaurate complex (GML) and antibiotic (acetylisovaleryltylosin tartrate, ATLL) supplementation during late gestation and lactation on the reproductive performance of sows and the growth performance of piglets. In total, 64 pregnant sows were randomly divided into control, antibiotic, 0.1% GML, and 0.2% GML groups. The GML shortened their delivery interval and farrowing duration. The ATLL increased the level of malondialdehyde (MDA) in sows and piglets and enhanced glutathione peroxidase (GSH-Px) in piglets, while reducing the tumor necrosis factor-α (TNF-α) level in sows. The GML tended to increase milk protein in the colostrum and decreased the TNF-α of sows at lactation. Meanwhile, 0.2% GML increased the serum total superoxide dismutase (T-SOD) activity and interleukin-6 level in weaned piglets and decreased the TNF-α level in sows and weaned piglets. Furthermore, ATLL decreased the microbial diversity of sows, and GML tended to increase the microbial diversity of sows and piglets. The ATLL group had an increased relative abundance of Bacteroidota in weaned piglets. The GML decreased the relative abundance of Peptostreptococcales-Tissierellales, Proteobacteria, and the harmful bacteria <i>Romboutsia</i> in sows. Compared with the ATLL group, the 0.2% GML reduced the relative abundance of Bacteroidota in weaned piglets. Interestingly, both ATLL and GML supplementation decreased the relative abundance of harmful bacteria Peptostreptococcaceae in sows. Correlation analysis also found positive effects of ATLL and GML in anti-inflammatory and antioxidant aspects. In conclusion, GML enhanced reproductive and growth performance by improving antioxidant and anti-inflammatory status and maintaining intestinal flora balance, making it a promising alternative to ATLL in future applications. |
