The influence of extruding vs pelleting of a feed mixture on nitrogen, dry matter, fat and ash digestibility was investigated in six mature dogs. Extrusion decreased nitrogen digestibility, increased ash absorption and had no effect on dry matter and fat digestibility. After feeding the extruded diet, the pH of faeces was lowered and the faecal water content increased, suggesting that this diet stimulated bacterial fermentation in the intestine.
