断奶期是羔羊生长发育和瘤胃功能的重要时期。因此，提高断奶羔羊生长性能的新型饲料添加剂不断被开发和研究。在此基础上，研究了日粮中添加单月桂酸甘油酯（GML）或GML与三丁酸甘油酯（TB）的组合（Solider，SOL）对断奶羔羊生长性能和瘤胃微生物的影响。在本研究中，日粮中添加GML或SOL可提高断奶羔羊的生长性能和养分消化率。此外，GML或SOL补充改变了瘤胃微生物组，例如通过增加放线菌和疣微菌的相对丰度并降低瘤胃球菌的相对丰度。总之，本研究为GML和SOL在断奶羔羊中的应用提供了新的见解。我们的目的是评估日粮中添加单月桂酸甘油酯（GML）或GML和三丁酸甘油酯（TB）的组合（Solider，SOL）对断奶羔羊的生长性能和瘤胃微生物组的影响。36只体重为11.46 ± 0.88 kg，40 ± 5日龄的湖羊公羔随机分为3个处理组：（1）CON组：基础日粮;（2）GML组：在基础日粮中添加1.84 g/kg干物质的GML;与CON相比，GML增加了最终BW（p = 0.04）和ADG（p = 0.02）。三个处理组之间的DMI无显著差异（p > 0.10）。GML和SOL有降低干物质采食量/平均日增重的趋势与对照组相比，GML组有提高CP表观消化率的趋势（p = 0.07（p = 0.08）与对照组相比，SOL组NDF表观消化率显著提高SOL组的Chao 1指数和Shannon指数均显著高于其他各组（p = 0.01）。LefSE分析表明，双歧杆菌目中双歧杆菌科在GML群中富集。另外，与GML相比，SOL降低了放线菌的相对丰度（p < 0.01），增加了疣微菌的相对丰度（p = 0.05），而GML降低了瘤胃球菌的相对丰度（p = 0.03）。结果表明，日粮中添加GML或SOL可提高断奶羔羊的生长性能和饲料转化率，并改变瘤胃微生物群。
The weaning period is important for the growth and ruminal function of lambs. Therefore, novel feed additives that improve the growth performance of weaned lambs are continuously being developed and researched. On this basis, the effects of dietary supplementation with glycerol monolaurate (GML) or the combination (Solider, SOL) of GML and tributyrin (TB) on the growth performance and rumen microbiome of weaned lambs were studied. In this study, dietary supplementation with GML or SOL improved the growth performance and nutrient digestibility of weaned lambs. In addition, GML or SOL supplementation changed the rumen microbiome, such as by increasing the relative abundance of Actinobacteria and Verrucomicrobia and decreasing the relative abundance of Ruminococcus. In summary, the study provides new insights into the application of GML and SOL in weaned lambs. Our objective was to evaluate the effects of dietary supplementation with glycerol monolaurate (GML) or the combination (Solider, SOL) of GML and tributyrin (TB) on the growth performance and rumen microbiome of weaned lambs. Thirty-six male Hu lambs (11.46 ± 0.88 kg BW and 40 ± 5 days of age) were divided into three treatment groups: (1) CON: basal diet, (2) GML: basal diet supplemented with GML at 1.84 g/kg DM, and (3) SOL: basal diet supplemented with SOL at 3 g/kg DM. GML increased the final BW (p = 0.04) and ADG (p = 0.02) compared with CON. There were no significant differences in the DMI (p > 0.10) among the three treatment groups. GML and SOL tended to decrease the dry matter intake/average daily gain (p = 0.07) compared with CON. GML tended to increase the apparent digestibility of CP (p = 0.08) compared with CON. SOL increased the apparent digestibility of NDF (p = 0.04) compared with CON. The Chao1 and Shannon indexes of SOL were both significantly higher than those of the other groups (p = 0.01). LefSE analysis showed that Bifidobacteriaceae of the Bifidobacteriales was enriched in the GML group. In addition, compared with GML, SOL reduced the relative abundance of Actinobacteria (p < 0.01) and increased the relative abundance of Verrucomicrobia (p = 0.05), and GML reduced the relative abundance of Ruminococcus (p = 0.03). Our results indicated that dietary supplementation with GML or SOL improved growth performance and feed conversion, and changed the rumen microbiome of weaned lambs.
