The aim of the present study was to evaluate the effects of Aloe arborescens on organic matter neflintw-r6mpw 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 read more 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.
