猪饲料中添加益生菌对肠道健康及生长性能的影响
摘 要
在现代养猪业中，肠道健康直接影响猪的生长性能、饲料利用率以及整体健康状况。益生菌作为一种天然、环保的饲料添加剂，近年来因其对动物肠道健康的潜在益处而备受关注。益生菌能够调节肠道微生物群，促进有益菌的增殖，抑制有害菌的生长，从而维护肠道微生态平衡。本研究旨在探讨益生菌对猪肠道健康及生长性能的影响，通过综合分析益生菌对肠道微生物群的调节作用、肠道屏障功能的改善机制以及肠道炎症的抑制作用，揭示了益生菌在改善猪肠道健康方面的作用机制。同时，本研究还考察了益生菌对猪采食量、体重增长和饲料转化效率的影响，进一步验证了益生菌在提高猪生长性能方面的有效性。此外，研究还比较了不同类型益生菌在猪饲料中的应用效果，分析了益生菌与其他饲料添加剂的协同作用，为益生菌在养猪业中的实际应用提供了科学依据。最后，本研究展望了益生菌未来的研究方向和产业化应用前景，为养猪业的可持续发展提供了有益的参考。

EFFECT OF ADDING PROBIOTICS IN PIG FEED ON INTESTINAL HEALTH AND GROWTH PERFORMANCE
ABSTRACT
In the modern pig industry, intestinal health directly affects the growth performance, feed utilization rate and the overall health status of pigs. As a natural and environmentally friendly feed additive, probiotics have attracted much attention in recent years due to their potential benefits on animal intestinal health. Probiotics can regulate the intestinal microbiota, promote the proliferation of beneficial bacteria, inhibit the growth of harmful bacteria, so as to maintain the balance of intestinal microecology. The purpose of this study is to investigate the effects of probiotics on the intestinal health and growth performance of pigs. By comprehensively analyzing the regulatory effect of probiotics on the intestinal microbiota, the improvement mechanism of intestinal barrier function and the inhibitory effect of intestinal inflammation, we revealed the action mechanism of probiotics in improving the intestinal health in pigs. Meanwhile, this study also examined the effects of probiotics on feed intake, body weight growth and feed conversion efficiency, and further verified the effectiveness of probiotics in improving pig growth performance. In addition, the study also compared the application effect of different types of probiotics in pig feed, and analyzed the synergistic effect of probiotics and other feed additives, which provided a scientific basis for the practical application of probiotics in pig industry. Finally, this study prospects the future research direction and industrial application prospect of probiotics, which provides a useful reference for the sustainable development of pig industry.
