Description

<p>To determine changes in the intestinal microflora (fecal microflora and digestibility coefficients) of cats fed a meat diet, four adult castrated male cats were fed a control food (commercial dry food) and a test food that was a mixture of the control food and a commercial venison wet food for 30 days (a 25-day acclimation period and a 5-day fecal collection period). The control and test foods were termed dry and dry＋wet foods, respectively. The dry (commercial dry food) and wet (commercial venison wet food) foods were mixed in a ratio of 1 : 4 for preparing the dry＋wet food. The feeding trial was conducted in accordance with the experimental design of the cross-over design, in which two types of food were fed. At the family level, the percentages of Coriobacteriaceae, Peptostreptococcaceae, Fusobacteriaceae, and Sutterellaceae were higher in cats fed with the dry＋wet food than in cats fed with the dry food (P＜0.05). The percentage of Erysipelotrichaceae was lower in cats fed with the dry＋wet food (P＜0.05). The cats fed the dry＋wet food had higher percentages of Fusobacterium and Sutterella at the genus level (P＜0.05). Thus, these results indicate that feeding a meat diet to cats alters their intestinal microflora. As for digestibility coefficients, digestibility of crude protein was lower when cats were fed the dry＋wet food than cats fed with the dry food (P＜0.05). These results may be related to the fact that the dry＋ wet food is a high-protein food.</p>
