Up to 60% of neonates can be affected by gastroenteritis due to specific pathogens or aspecific polymicrobial interactions. The present study evaluated if a dietary supplementation with MOS, FOS, and in pregnancy may reduce gastroenteritis in puppies. Fifteen Great Danes were divided in 3 groups. The control group (CG) ate a standard diet. In 2 study groups, the diet was supplemented with pre- and probiotics during the last (1WG) and the last 4 pregnancy weeks (4WG). Up to 9 weeks, puppies were checked daily to identify first- or second- presentation gastroenteritis. Data were processed by χ ( < 0.05). First-presentation gastroenteritis was more frequent in CG than in 1WG than in 4WG. Second-presentation gastroenteritis was more frequent in CG than in 1 and 4WG. Puppies from pre- and probiotics supplemented bitches were less prone to gastroenteritis. 1 or 4WG equally reduced second-presentation gastroenteritis in puppies, but 4WG was better than 1WG on first-presentation gastroenteritis. By entero-mammary link, supplemented bitches produced higher immune quality colostrum, thus puppies faced immunitary challenges better; moreover, maternal microbiota, positively altered by supplementation, was transferred to newborns, becoming more resistant to gastroenteritis. This information can be useful in clinical practice with the goal of preventing gastroenteritis in puppies and reducing its prevalence and severity.
高达60%的新生儿可能会因特定病原体或非特异性微生物相互作用而患肠胃炎。本研究评估了孕期补充甘露寡糖(MOS)、低聚果糖(FOS)是否可以降低幼犬患肠胃炎的几率。15只大丹犬被分为3组。对照组(CG)食用标准饮食。在2个研究组中,母犬在妊娠最后1周(1WG)和最后4周(4WG)的饮食中添加了益生元和益生菌。在9周龄之前,每天对幼犬进行检查,以确定首次或第二次出现肠胃炎的情况。数据采用χ检验处理(<0.05)。首次出现肠胃炎的情况在CG组比1WG组更频繁,1WG组又比4WG组更频繁。第二次出现肠胃炎的情况在CG组比1WG组和4WG组更频繁。补充了益生元和益生菌的母犬所生的幼犬患肠胃炎的可能性较小。1WG组和4WG组在同等程度上降低了幼犬第二次出现肠胃炎的几率,但在降低幼犬首次出现肠胃炎的几率方面,4WG组比1WG组效果更好。通过肠-乳腺联系,补充了益生元和益生菌的母犬产生了免疫质量更高的初乳,因此幼犬能更好地应对免疫挑战;此外,因补充而产生积极变化的母源微生物群被传递给了新生幼犬,使其对肠胃炎更具抵抗力。这些信息在临床实践中可能有用,其目的是预防幼犬患肠胃炎并降低其发病率和严重程度。
