平衡的微生物系统是仔猪健康的重要标志。影响肠道微生物区系的关键因素之一是宿主的遗传。本研究探讨了萨巴(SB)仔猪和长白(LA)仔猪空肠微生物区系多样性的差异。9头萨巴仔猪和9头长白仔猪饲喂母猪奶，直到第35天。收集空肠内容物进行16S rRNA测序。萨巴仔猪的初生重、体重和日增重均低于长白仔猪(p<；0.01)。萨巴仔猪和长白仔猪的主要类群是菌类，萨巴仔猪的拟杆菌数量高于长白仔猪(p<；0.05)。长白猪和萨巴仔猪空肠中最丰富的两个属是乳杆菌和梭状芽胞杆菌。与长白仔猪相比，萨巴仔猪Veillonella、链球菌和糖化细菌属的丰度显著降低(p<；0.05)。功能预测表明，萨巴仔猪富含“d-谷氨酰胺和d-谷氨酸代谢途径”和“叶酸一碳库”途径，而长白仔猪富含“柠檬烯和蒎烯降解途径”、“色氨酸代谢途径”和“硫传递系统途径”。综上所述，由于长白仔猪的遗传特性，长白仔猪的生长性能高于萨巴仔猪。萨巴仔猪具有丰富的多样性和较少的感染相关类群，部分原因是它们比长白仔猪对环境扰动有更高的适应能力。此外，不同品种的猪可能通过不同的代谢途径来调节自己的健康。
The balanced microbiological system is a significant hallmark of piglet health. One of the crucial factors affecting intestinal microbiota is the host’s genetics. This study explored the difference in the diversity of jejunal microbiota between Saba (SB) and Landrace (LA) piglets. Nine Saba and nine Landrace piglets were fed with sow’s milk until day 35. Jejunal contents were harvested for 16S rRNA sequencing. The birth weight, body weight, and average daily gain of Saba piglets were lower than those of Landrace piglets (p < 0.01). Firmicutes were the main phylum in Saba and Landrace piglets, and the Saba piglets had a higher (p < 0.05) abundance of Bacteroidetes compared with Landrace piglets. The two most abundant genera were Lactobacilli and Clostridium XI in the jejunum of Landrace and Saba piglets. Compared with Landrace piglets, the Saba piglets had significantly lower (p < 0.05) abundance of Veillonella, Streptococcus, and Saccharibacteria genera incertae sedis. The functional prediction showed that “d-glutamine and d-glutamate metabolism” and “one carbon pool by folate” pathways were enriched in Saba piglets, while “limonene and pinene degradation”, “tryptophan metabolism”, and “sulfur relay system” pathways were enriched in Landrace piglets. In summary, the growth performance was higher for Landrace piglets compared with Saba piglets due to their genetic characteristics. The rich diversity and fewer infection-associated taxa were observed in Saba piglets, partially accounting for their higher adaptability to environmental perturbations than Landrace piglets. Furthermore, different pig breeds may regulate their health through different metabolic pathways.
