摘要

不同的饮食模式会影响肠道微生物的组成和多样性。微生物组的改变始终与消化、免疫和生产力有关。Sasa quelpaertensis Nakai(SQ)是一种富含蛋白质和纤维的多年生竹子。以前的研究已经证实了 SQ 对健康的益处,但补充 SQ 对肠道微生物组和生产性能的影响尚不清楚。在此,使用 16S rRNA 测序法对补充 SQ 提取物(SQE)的陆地猪和对照组的肠道微生物组成进行了评估。此外,屠宰后还评估了补充 SQE 对平均日增重(ADG)和背膘厚度(BF)的影响。在 SQE 组中,固缩菌和放线菌的表达量显著增加,而类杆菌和螺旋体的表达量明显减少(p < 0.05)。双歧杆菌属和乳酸杆菌属的表达水平上升,而特雷伯菌属、普雷沃菌属和土里菌属的表达水平下降(p < 0.05)。各组之间的微生物丰富度相似,但补充 SQE 组的微生物多样性有所降低。此外,补充 SQE 的猪的日增重略有增加。相比之下,SQE 组的 BF 显著下降(p < 0.05)。这些结果强调了补充 SQE 对肠道微生物群的重大影响,并证明了 SQ 作为一种有价值的饲料资源在提高动物生产率方面的潜力。

Effect of Sasa quelpaertensis Nakai extract on gut microbiota and production performance in pigs.

Different dietary patterns affect the gut microbial compositions and diversity. Consistently, microbiome alterations are linked to digestion, immunity, and productivity. Sasa quelpaertensis Nakai (SQ) is a perennial bamboo species rich in proteins and fiber. Previous studies have confirmed the health benefits of SQ; however, the effects of SQ supplementation on gut microbiome and production performance are unclear. Herein, Landrace pigs were supplemented with SQ extract (SQE) and gut microbial compositions as opposed to the control group were assessed using 16S rRNA sequencing. Additionally, the influences of SQE supplementation on average daily gain (ADG) and backfat thickness (BF) were assessed after slaughter. In the SQE group, Firmicutes and Actinobacteria phyla increased significantly, whereas Bacteroidetes and Spirochaetes phyla markedly decreased (p < 0.05). The expression level of Bifidobacterium and Lactobacillus genera increased, whereas that of Treponema, Prevotella, and Turicibacter decreased (p < 0.05). The microbial richness was similar between groups; however, microbial diversity decreased in the SQE supplementation group. Additionally, the SQE supplementation in pigs resulted in a slight increase in ADG. In contrast, BF in the SQE group decreased notably (p < 0.05). These results underscore the significant influence of SQE supplementation on the gut microbiota and demonstrate the potential of SQ as a valuable feed resource for enhancing animal productivity.

期刊介绍: Journal of Animal Science and Technology (J. Anim. Sci. Technol. or JAST) is a peer-reviewed, open access journal publishing original research, review articles and notes in all fields of animal science. Topics covered by the journal include: genetics and breeding, physiology, nutrition of monogastric animals, nutrition of ruminants, animal products (milk, meat, eggs and their by-products) and their processing, grasslands and roughages, livestock environment, animal biotechnology, animal behavior and welfare. Articles generally report research involving beef cattle, dairy cattle, pigs, companion animals, goats, horses, and sheep. However, studies involving other farm animals, aquatic and wildlife species, and laboratory animal species that address fundamental questions related to livestock and companion animal biology will also be considered for publication. The Journal of Animal Science and Technology (J. Anim. Technol. or JAST) has been the official journal of The Korean Society of Animal Science and Technology (KSAST) since 2000, formerly known as The Korean Journal of Animal Sciences (launched in 1956).
