摘要： Probiotics have been used in functional foods and dietary supplements, and in recent years, they have become more widely used in pets. In our previous experiment, Lactobacillus plantarum L-27-2 and Pediococcus lactis L-14-1 were isolated from cat feces and proved to have positive effects on lipid metabolism in mice. To further discuss their possible effects in cats, a total of 12 healthy cats (British Shorthair) were randomly divided into two groups. One group was fed Pediococcus lactis L-14-1 (1 x 10(9) CFU/kg/d, n = 6), and the other group was fed Lactobacillus plantarum L-27-2 (1 x 10(9) CFU/kg/d, n = 6), and the experiment was conducted for 28 days. Blood and feces were collected on days 0 and 28 separately. ELISA was used to detect blood biochemical indexes in cats. The results showed that L-27-2 and L-14-1 could reduce the content of TG (triglyceride, p < 0.05) and LDL-C (low-density lipoprotein cholesterol, p < 0.01) in the blood, increase the content of HDL-C (high-density lipoprotein, p < 0.01), and L-27-2 could significantly reduce the content of IL-6 (p < 0.01). The diversity of feces microbiota was also tested. On the phylum level, there was no significance in the phylum level of Firmicutes and Bacteroidetes (p > 0.05), but on the genus level, in the L-14-1 group, the abundance of Lantiplantibacillus and Cetobacterium was increased (p < 0.05), and the abundance of Ruminococcus, Olsenella, and Labanicoccus was decreased (p < 0.05), while in the L-27-2 group, the abundance of Libanicoccus was also decreased in L-14-1 (p < 0.05). Above all, L-27-2 and L-14-1 can be considered potential probiotics to improve cat gut health and lipid metabolism.
