Pulse-based pet foods often contain peas or pea starch, which tend to impart a bitter taste. Fermentation increases feed palatability, but also has the potential to improve overall health. Therefore, the current study used the yeast, to ferment pea starch for use in pet food and assessed health effects, focusing on metabolic and intestinal health in dogs and cats. Whole diets had ~30% starch inclusion of either -fermented pea starch, unfermented pea starch, or a control corn diet fed over a 20-day period to beagle dogs and domestic cats. Complete blood count, biochemistry, adipokines, and triglyceride levels were assessed, along with fecal short chain fatty acids, microbial diversity and abundance to measure intestinal health. It was found that pea-based diets (regardless of fermentation) generally resulted in improved metabolic health by both species, indicated by lower plasma triglycerides, cholesterol, and leptin levels compared to the control corn diet. Additionally, the -fermented pea starch diet improved dog fecal microbial diversity, while both pea diets increased richness and evenness in the microbial population and a larger population compared to dogs fed the corn-based diet. In contrast, cat microbiome could not be quantitatively evaluated due to poor fecal quality. Taken together, inclusion of pea starch improves metabolic and intestinal health after 20 days consumption in dogs, while fermentation of pea starch with may provide additional benefit.
基于豆类的宠物食品通常含有豌豆或豌豆淀粉，这往往会带来苦味。发酵可提高饲料适口性，但也有改善整体健康的潜力。因此，本研究使用酵母发酵豌豆淀粉用于宠物食品，并评估其对健康的影响，重点关注犬猫的代谢和肠道健康。将全价日粮中含有约30%淀粉的发酵豌豆淀粉、未发酵豌豆淀粉或对照玉米日粮，在20天的时间内喂给比格犬和家猫。评估全血细胞计数、生化指标、脂肪因子和甘油三酯水平，以及粪便短链脂肪酸、微生物多样性和丰度以衡量肠道健康。结果发现，基于豌豆的日粮（无论是否发酵）通常能改善两种动物的代谢健康，与对照玉米日粮相比，血浆甘油三酯、胆固醇和瘦素水平较低表明了这一点。此外，发酵豌豆淀粉日粮改善了犬的粪便微生物多样性，而两种豌豆日粮都增加了微生物种群的丰富度和均匀度，并且与喂食玉米日粮的犬相比，种群更大。相比之下，由于粪便质量差，无法对猫的微生物组进行定量评估。综上所述，食用20天后，豌豆淀粉的添加改善了犬的代谢和肠道健康，而用酵母发酵豌豆淀粉可能会带来额外的益处。
