Abstract

Abstract The aim of the present study was to evaluate the effects of Aloe arborescens on organic matter digestibility (OMD), cumulative gas (OMCV) and short chain fatty acids (SCFA) production, using the in vitro gas production technique (IVGPT). Three adult cats were fed with a commercial diet (CP 31.21; EE 16.64% as fed) for 20 days before the collection of their faeces used as inoculum. The same diet, used as substrate, was incubated in vitro supplemented with different amounts (0, 0.7, 1.6 and 3.2%) of lyophilised Aloe arborescens. OMD, OMCV and SCFA significantly decreased with the increase of Aloe addition; an increase of l-lactic acid production was detected, even if pH was within physiological range. A potential prebiotic role of the Aloe arborescens carbohydrates was hypothesised in cats, but it needs further investigations. As a whole, our results show that IVGPT can represent a useful tool for nutritional evaluation of novel ingredient and/or additive also in cats.

猫粮中芦荟的补充:体外产气技术的效果评价

摘要本研究旨在利用体外产气技术(IVGPT)研究芦荟对有机物质消化率(OMD)、累积气体(OMCV)和短链脂肪酸(SCFA)产生的影响。3只成年猫饲喂商业饲粮(CP 31.21;EE(16.64%)饲养20 d，然后收集粪便作为接种物。以相同的饲料为底物，在体外培养中添加不同量(0,0.7,1.6和3.2%)的芦荟冻干。随着芦荟添加量的增加，OMD、OMCV和SCFA显著降低;即使pH在生理范围内，也能检测到l-乳酸产量的增加。假设芦荟碳水化合物在猫体内具有潜在的益生元作用，但还需要进一步的研究。总的来说，我们的结果表明，IVGPT可以作为一种有用的工具来评估猫的新成分和/或添加剂。
