摘要： The gut microbiota is the largest and most complex ecosystem consisting of trillions of microorganisms, which influenced by various external factors. As an important probiotic species, Lactobacillus helps to improve gut microbial diversity and composition, underlying potential efficacy in growth performance and disease prevention. However, limited studies have been investigated the relationship between Lactobacillus sakei and intestinal health in dogs. In this study, dogs in the two groups were fed a standard diet (group C, n = 8) and Lactobacillus sakei diet (group P, n = 8), respectively. The growth performance, serum biochemical indices, antioxidant capacity, gut microbiota, and metabolism of dogs in both groups were studied. Results from growth trials showed that L. sakei can significantly improve the growth performance of dogs, including increased weight gain (p < 0.05), serum biochemical indices, i.e., ALP, TP, and ALB (p < 0.05), and better antioxidant capacity, i.e., SOD and GSH-Px (p < 0.05). Significant changes in the gut microbial composition were detected in dogs fed Lactobacillus sakei, as evidenced by an increase in the level of Firmicutes, Spirochaetota, and Patescibacteria, all of them play an important role in maintaining intestinal health. Moreover, a decrease in the level of microorganisms that threaten health, such as Mucispirillum and Clostridium_sensu_stricto_13. The metabolic analysis showed that the Lactobacillus sakei enhanced metabolic pathways such as vitamin B6 metabolism, glutathione metabolism, retinol metabolism, and fatty acid degradation. Our findings suggested that Lactobacillus sakei supplementation had beneficial effects on the growth performance and health status of dogs by improving gut microbiota balance and promoting metabolism. There are an estimated 200 million dogs in China, and the population is continuing to grow at a rapid pace. It is essential to explore an effective way to promote health in dogs. Intestinal diseases, particularly colitis and diarrhea, are common clinical conditions in dogs and are associated with gut microbiota. Lactobacillus sakei, as an important species of probiotics, the relationship between L. sakei and intestinal health in dogs remains unclear. Our study suggests that L. sakei significantly promotes growth performance and health states involving weight gain, regulation of gut microbiota, and metabolism. Overall, our findings shed light on the potential role of L. sakei as an alternative in promoting health in dogs.
