Prebiotics are important for gut health and immunity in animals and could promote the growth of beneficial bacteria. The objective of this study was to investigate the prebiotic potential of lactobin and glucans when combined with goat's milk in the diet of cats. Twenty-four healthy cats (all about 2 y old) were randomly assigned to 4 treatment groups. Group A was the control untreated group, Group B received supplementation with 30 mL of goat's milk plus 20 mg of bovine colostrum, and Groups C and D were given 30 mL of goat's milk plus 20 mg of beta-glucan from different companies. On day 28, samples of blood and feces were collected for the evaluation of serum biochemistry, secretory immunoglobulin A (SIgA) and microbiota in the feces. It was discovered that β-glucan significantly increased the level of SIgA in blood ( < 0.05) and the relative abundance of was greatly increased at the genus level ( < 0.05). Compared with the control group, the content of total bile acids in cats in Group D was higher than that in the other treatment groups ( < 0.05), whereas there was no significant variation in other blood parameters among the different groups ( > 0.05). This suggests that β-glucan and lactobin has potential prebiotic properties in cats.
益生元对动物的肠道健康和免疫力很重要，并且可以促进有益细菌的生长。本研究的目的是调查乳清蛋白和葡聚糖与羊奶混合添加到猫粮中时的益生元潜力。将24只健康猫（均约2岁）随机分为4个处理组。A组为未处理的对照组，B组补充30毫升羊奶加20毫克牛初乳，C组和D组分别给予30毫升羊奶加来自不同公司的20毫克β-葡聚糖。在第28天，采集血液和粪便样本，用于评估血清生化指标、粪便中的分泌型免疫球蛋白A（SIgA）和微生物群。结果发现，β-葡聚糖显著提高了血液中SIgA的水平（<0.05），并且在属水平上大大增加了[此处原文缺失具体菌群名称]的相对丰度（<0.05）。与对照组相比，D组猫的总胆汁酸含量高于其他处理组（<0.05），而不同组之间的其他血液参数没有显著差异（>0.05）。这表明β-葡聚糖和乳清蛋白在猫中具有潜在的益生元特性。
