There have been few investigations into the health benefits and meat quality of supplementing Yangzhou geese with paper mulberry silage. One hundred and twenty 28-day-old Yangzhou geese were selected for the experiment and randomly divided into two groups: a control group (CON) and a paper mulberry silage group (PM), with six replicates in each group. The experiment lasted for a total of 6 weeks. The experiment found that compared with CON, PM had a promoting effect on the average daily weight gain of Yangzhou geese ( = 0.056). Sensory and nutritional analysis of breast muscles revealed a decrease in a* value ( < 0.05) and an increase in protein content ( < 0.05) following PM treatment. Through untargeted metabolomics analysis of breast muscle samples, it was found that 11 different metabolites, including guanidinoacetic acid and other substances, had a positive effect on amino acid metabolism and lipid antioxidant pathways of PM treatment. Overall, the strategy of feeding Yangzhou geese with paper mulberry silage is feasible, which can improve the sensory quality and nutritional value of goose meat. The experiment provides basic data for the application form of goose breeding, so exploring the impact of substances within paper mulberry on goose meat should be focused on in the future.
关于用构树青贮料补饲扬州鹅对其健康益处和肉质的研究较少。选取120只28日龄的扬州鹅进行试验，随机分为两组：对照组（CON）和构树青贮料组（PM），每组6个重复。试验共持续6周。试验发现，与CON组相比，PM组对扬州鹅的平均日增重有促进作用（P = 0.056）。对胸肌的感官和营养分析表明，PM处理后a*值降低（P < 0.05），蛋白质含量增加（P < 0.05）。通过对胸肌样本进行非靶向代谢组学分析，发现包括胍基乙酸等11种不同代谢物对PM处理的氨基酸代谢和脂质抗氧化途径有积极影响。总体而言，用构树青贮料饲喂扬州鹅的策略是可行的，可提高鹅肉的感官品质和营养价值。该试验为鹅养殖的应用形式提供了基础数据，因此未来应重点探索构树中的物质对鹅肉的影响。
