Faecal analysis for undigested/unabsorbed food particles and protease activity was performed on multiple samples obtained from four normal dogs each fed four different diets. All four diets, irrespective of the dog, produced a consistent faecal appearance and microscopic findings for undigested/unabsorbed food particles. Cooked and raw minced meat diets produced similar results: stools, which were small, green-brown, firm and glutinous, had little starch, occasional undigested short muscle fibres and moderate amounts of soap. Stools from the dogs on Pal were large, red-brown, solid to semi-solid, and moist; they contained little starch, occasional short undigested muscle fibres and little fat. The Loyal diet produced large, light yellow, dry, friable stools which had variable but usually low starch, no muscle fibres and no fat. Faecal protease activity for the different diets was analysed statistically. Differences in faecal protease activity due to different diets were evident but complicated by differences due to individual dogs.
对从四只正常犬获取的多个样本进行粪便分析，每只犬分别喂食四种不同的日粮，分析未消化/未吸收的食物颗粒和蛋白酶活性。所有四种日粮，无论涉及哪只犬，对于未消化/未吸收的食物颗粒均产生一致的粪便外观和微观检查结果。煮熟的碎肉日粮和生碎肉日粮产生相似的结果：粪便小，呈绿褐色，坚实且黏腻，几乎没有淀粉，偶尔有未消化的短肌纤维，并有适量皂质。喂食Pal日粮的犬的粪便大，呈红褐色，固体至半固体，且湿润；几乎没有淀粉，偶尔有短的未消化肌纤维，几乎没有脂肪。喂食Loyal日粮产生的粪便大，呈浅黄色，干燥且易碎，淀粉含量不定但通常较低，没有肌纤维，也没有脂肪。对不同日粮的粪便蛋白酶活性进行了统计分析。不同日粮导致的粪便蛋白酶活性差异明显，但因个体犬的差异而变得复杂。
